Model RLD2 冷却漏气检测器设施安装和操作说明说明书

Model RLD2 Refrigerant Leak DetectorSpecifications - Installation and Operating InstructionsBulletin TE-RLD2 The Model RLD2 Refrigerant Leak Detector is the most dependable negativecorona refrigerant leak detector. The responsive elements have a wide sensitivityrange. This unit utilizes a five level alarm system to detect excessive refrigerant inareas where there could be a potential leak. The dual-color LED indicator lightsprovide visual indication of the refrigerant gas concentration, various audio pitchesfacilitate detection, and its portable design is convenient for the user. The refrigerantleak detector can be utilized in residential and commercial refrigeration systems,automotive, air conditioning, and quality control testing environments.TECHNICAL FEATURESThis device consumes low power by utilizing an 8–bit microprocessor controller. Alsoequipped is dual-colored LED indicator light with progressive and real time display.The sensitivity is adjustable with seven level alarming indicated by the audio levels andLED display. The indicators are convenient for maintenance because of the modular sensor, battery voltage indication and auto rest testing when the detector is turned on. OPERATION KEYS• ON/OFF KeyPress it to turn on/off the detector.• SENS KeyIt is the sensitivity adjustment key, it can adjust the sensitivity level according to the detection demands (max level:7). LED light will indicate the level of sensitivity, meanwhile the frequency of audible alarm changes. The higher the sensitivity level, the faster the alarm frequency.• RESET KeyReset the background halogen level to “zero”, any leak sources higher than “zero”level is considered to be a leak and trigger the alarm.Before Operating the Leak Detector:In order to detect leaks in a refrigerant system, the system must have normal operating pressure, or at least reach a minimum of 50 PSI. Low environmental temperature (lower than 59°F or 15°C) may lower the system required pressure and may make the leak less likely to be detected. No leak detected does not mean the system does not have a refrigerant gas leak. Check the pressure before making the conclusion. Leaking areas are usually covered with contaminants such as a compressor oil or dirt, be careful not to let the sensor tip touch with these contaminants. This product’s function is to detect halogen’s relative change at the sensor tip. Pinpointing the leak source needs to be done manually by adjusting the sensitivity and resetting thedetector by the user.®Printed in U.S.A. 2/19FR# 444134-00 Rev. 2©Copyright 2019 Dwyer Instruments, Inc.OPERATION1. Turn the detector on by pressing the ON/OFF key. All LED indicator lights will be on for 3 seconds, and the detector will automatically reset. A rapid, steady beep will also be heard.2. After the auto-reset, only the first LED indicator light on the left will be on. This is the power indicator light (see battery voltage indication section for more information).3. Begin searching for leaks. When refrigerant is detected, an audible buzzer will sound with a different rate than the previous beeping sound. Also, the indicator lights will progressively turn on.4. The sensitivity cap can be adjusted at any time during operation by pressing the SENS key. This adjustment will not interrupt detection. The default sensitivity level is level5.5. If an alarm occurs before the sensing tip touches the leakage source, press the RESET key to reset the current to zero until there is no alarm, then continue detecting.6. When done using, press the ON/OFF key to turn off the detector.Detecting Method1. Visually examine the refrigeration system. The oily and dirty spots, node valves, coils, connectors, or pipelines are the areas most likely to leak gases.2. Start leak detecting at the joint at a distance of about 1 to 3 cm, moving at a speed of about 1 cm/s.3. When an alarm is triggered, it may indicate a leak is close by. Detect around that area again and see if the alarm is repeatable. If a leak is confirmed, pinpoint the leak source by moving slowly from the non-leaking to the leaking area from different directions. Another method to pinpoint the leak is to move the detector away from the leaking area, reset the unit, and repeat the above process. Once confirmed, mark around the leak and continue detecting the whole line of the system.4. Additional work may be needed to eliminate possible ambiguity, such as other contaminants in the area of the leak. Clean the leaking area with a dry cloth and blow with clean, dry air, and repeat step 3 to confirm the leak.Recommendations Based on EnvironmentDepending on the environment around the leak, different methods may need to be used to detect properly.1. In areas where the atmosphere is contaminated with the refrigerant, press the RESET key to make the detector ignore the leak in the background. Make sure not to move the sensor tip away from the contaminated background while resetting the detector.2. In windy areas, the leaked halogen refrigerant may be quickly diluted or removed from the leak source. The user may use a wind shield to isolate the leak area or temporarily turn off the fan.3. To avoid false alarm, prevent the sensor tip from touching any moisture or other solvent.Battery Voltage IndicationUsers can check the battery level in the standby mode from the battery level indicator light. The color of the power indicator light will change according to the battery level. The indication of the colors are:Green Meets requirement for normal work. Orange Low battery working voltage.Red Below the permitted working voltage. Please replace the batteries as soon as possible.Battery Replacement1. Push open the battery door located at the bottom of the detector, then remove the door.2. Install two AA batteries into the detector, paying attention to the polarity marking on the side of the case, and then place the battery door back.MAINTENANCEProper maintenance is important and may extend the service life and improve the performance of your detector.Keep the sensor tip clean: Use cotton cloth or dry air to clean the shield on the sensor tip if it gets contaminated. If the sensor tip itself is contaminated, soak the tip in absolute alcohol for a few minutes, and then use compressed air to blow it dry or dry it with cloth. Note: Never use strong solvents such as gasoline, mineral oil, or turpentine, as these solvents may coat the sensor with a thin film and reduce the sensitivity of the detector making the detector slow to respond to a leak. Put the detector and the tip in a dry and clean place; remove the batteries if the detector is not used for a long time. REPAIR/WARRANTYModel RLD2 is not field serviceable and should be returned if repair is needed. Field repair should not be attempted and may void warranty. Refer to “Terms and Conditions of Sale” in our catalog and on our website. Contact customer service to receive a Return Goods Authorization number before shipping the product back for repair. Be sure to include a brief description of the problem plus any additional application notes.To reduce the risk of igniting flammable gases in a closed atmosphere, batteries must only be replaced in an open area orclosed space without flammable gas.Turn the power off before replacing the sensor tip. Voltage across the tip may pose an electrical hazard.。

ButtonsTru Pointe® IR Refrigerant Leak Detector 2.3. LED IndicatorsFigure 5. LED Indicators2.4. Sensitivity SettingsThe Tru Pointe® IR has four sensitivity settings used to detect refrigerant leaks: Low, Medium, High (default at start-up), and Background.Use the high sensitivity setting to detect refrigerant leaks as small as 0.1 oz/yr (3 g/yr). Medium and low sensitivity settings can also be used for progressively larger leaks. Change this setting using the L/M/H button based on your preference, suspected leak type, and particular application. Consecutive presses of the L/M/H button will toggle the instrument through these three modes.NOTE! Generally, a retest is advisable when a leak is discovered usingthe most sensitive settings or if the probe was in a static position whenthe leak was discovered. In these cases, repeat the test ensuring theprobe moves past the suspected leak location while maintaining thesmallest possible gap between the suspected leak point and the tip ofthe probe. Also, consider using the Medium sensitivity position of thedetector after finding an apparent leak with the High sensitivity setting.A fourth sensitivity setting is Background Mode. Background Mode is the most sensitive operating mode of the Tru Pointe® IR.

Probe SelectionThe Tru Pointe®IR has a 15"(38.1 cm) flexible probe. For applications requiring additional reach, this probe may be extended using the 9" (22.9 cm) flexible probe extension. For targeted detection in confined locations, the 9"(22.9 cm) rigid “needle” probe extension may be used. Use an O-ring between probes, the probe tip, and any extensions (if used).Figure 6. Flexible and Rigid Probe Extensions2.6. Leak DetectionNOTE! The Tru Pointe® IR instrument detects changes in concentrationof refrigerant, not the absolute concentration of refrigerant. Thisallows the detection of leaks in locations that may have refrigerant inthe air, however, be sure to keep the probe tip moving during testing.NOTE! Some leaks may not be measurable if the pressure in the HVACsystem is too low. In such cases, you may need to charge the systemwith sufficient refrigerant to have a gauge pressure of at least 340 kPa(50 psi) with the system off.WARNING! The Tru Pointe® IR instrument is sensitive and can take upto 30 seconds to clear after detecting a small amount of contaminant.It will typically clear in 2 to 15 seconds.WARNING!Do not use cleaning agents or solvents on or near A/Clines. Wipe away any dirt or potential false-trigger chemicals using adry towel.To perform refrigerant leak detection, follow the instructions below.NOTE! Use shop air or compressed air to quickly clear a suspected area of refrigerant build-up, and then re-test. Do not use commercially available “canned” air to clear refrigerant build -up as it uses refrigerant as a propellant and will further contaminate the immediate area.Figure 7.

冷媒检漏仪的使用方法

冷媒检漏仪的使用方法冷媒检漏仪是一种专门用于检测冷却系统中冷媒泄漏的设备。

在冷却系统中，冷媒的泄漏问题是非常常见的，如果不及时发现和修复，不仅会导致制冷效果下降，还可能对环境造成污染。

因此，掌握冷媒检漏仪的使用方法是非常重要的。

使用冷媒检漏仪之前，需要确保设备已经接通电源并处于正常工作状态。

检漏仪通常会有一个开关按钮，将其打开即可开始使用。

在启动检漏仪之前，还需要检查设备是否已经连接到待检测的冷却系统上。

通常情况下，冷媒检漏仪会通过一个特定的接口与冷却系统连接，确保连接牢固可靠。

接下来，我们需要调整冷媒检漏仪的灵敏度。

不同的冷媒泄漏情况可能需要不同的灵敏度设置。

一般而言，灵敏度越高，检测到的泄漏量越小。

在冷媒检漏仪上，通常会有一个调节旋钮或按钮用于设置灵敏度。

根据实际情况，将灵敏度调整到适当的位置。

当冷媒检漏仪准备就绪后，我们可以开始进行泄漏检测了。

首先，需要选择一个检测点，通常是冷却系统的连接口或其他易泄漏的部位。

将冷媒检漏仪的探头放置在检测点上，并保持稳定。

然后，观察冷媒检漏仪的显示屏，通常会有一个数字或图表显示当前的泄漏量。

如果泄漏量超过了设定的灵敏度阈值，冷媒检漏仪会发出声音或光信号进行警示。

在检测过程中，需要注意一些细节。

首先，要确保检测环境的温度和湿度适宜。

过高或过低的温度都可能影响冷媒检漏仪的准确性。

此外，还要注意避免检测过程中的干扰。

比如，当附近有其他电子设备或强烈的电磁场时，可能会对冷媒检漏仪的工作产生干扰，导致误报或漏报。

除了以上的基本使用方法外，还有一些额外的使用技巧可以提高冷媒检漏仪的效果。

首先，可以使用氮气进行辅助检测。

将氮气注入冷却系统中，通过冷媒检漏仪检测氮气的泄漏情况，可以更准确地确定冷却系统的泄漏点。

此外，还可以利用冷却系统的压力变化情况来判断泄漏位置。

当冷却系统中的压力发生变化时，冷媒检漏仪会显示出相应的泄漏信号。

冷媒检漏仪是一种非常实用的设备，可以帮助我们及时发现和修复冷却系统中的冷媒泄漏问题。

This unit uses a newly developed semi-conductor sensor which is extremely sensitive to variety of general used Refrigerant • Microprocessor Control with advanced digitalsignal processing.• Multi color visual display.• High-median-Low leak sensitivity selector.• Low battery indication.• Semiconductor gas sensor.• Detection of R-134a, R-410A, R-407C, R22 Freon gas.• Carrying case included.• 15.5” (40 CM) flexible stainless probe.• Reference Leak source included.• Ambient concentration reset.• Long-life, DC brushless fan.• Automatic zero and background compensation.• AC Adapter:@3.3V 0.5AOPERATION1. The refrigerant leak detector unit is not equipped with anti-explosive designs and measures. Do not use this unit in the environment with the burnable gases.2. There are some environmental conditions that might cause error reading:• Pollutant places.• Large temperature variation.• Places with high wind velocity.• Organic solvent, adhesive vapor, fuel gas and vesicant will cause abnormal response from the sensor. Try to avoid the environment involved with this substance.• Places fill with too much to Freon Gas.LED Leak Indicator DefinitionPeriodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for periods of longer than 60 days, remove the battery and store separately.ConcentraionIndiction Concentraion IndictionAutomatic Ambient Reset FeatureThis Refrigerant leak detector features an Automatic Ambient Reset function that sets the unit to ignore ambient concentrations of refrigerant.• Automatic Ambient Setup - Upon initial poweron, the unit automatically sets itself to ignore thelevel of refrigerant present at the tip. Only a level,or concentration, greater than this will cause analarm.�CAUTION!Be aware that this feature will cause the unit toignore any refrigerant present at turn on. In otherwords, with the unit off if you place the tip up toa known leak and switch the unit on, no leak willbe indicated!• Ambient Reset Feature - Resetting the unit duringoperation performs a similar function it programsthe circuit to ignore the level of refrigerantpresent at the tip. This allows the user to ‘home-in’on the source of the leak (higher concentration).Similarly, the unit can be moved to fresh air andreset for maximum sensitivity. Resetting the unitwith no refrigerant present (fresh air) causes anylevel above zero to be detected.• After the unitis warmed up, the default sensitivity level is set at“Medium” and Auto Reset function is “ON”• Auto Reset function is best used initially whenuser is moving around trying to identify leakagesource. Once the leak source is determined, cancelthe Auto Detect function to proceed with leakagemeasurement.• Auto Reset function should be turned OFF whenuse in fixed position leakage detectionFeature Sensitivity AdjustmentThe Instrument provides three levels of sensitivity. When the unit is switched on, it is set to the Medium sensitivity level.• To change the sensitivity, press the “Lo” key.When the key is pressed, the visual display willmomentarily show the two bottoms LED’s (green)indicating Low Sensitivity level is selected.• To switch back to High Sensitivity, press the “Hi”key. The all LED’s (2 Green+2 Orange+3 Red) willlight momentarily indicating high Sensitivity levelis selected.Sensitivity level (Green LED)Sensitivity level(Orange LED)Sensitivity level(Red LED)How To Find Leaks?NOTE: A sudden whipping of the leak detector probeor “blowing” into the sensor tip will affect the air flow over the sensor and cause the instrument to alarm.(1) Power-Up keyThe + key turns the Refrigerant leak detectorinstrument ON or OFF function.Press it once to turn on the Refrigerant leakdetector, the display will illuminate with flash, for 45 seconds to heat up the sensor.Press and hold this button for 3 second to turn OFFthe power.(2) Auto Reset & Reset function keyWhen the Auto Reset function is turned ON, themeter will monitor background status and fine tune itself. When Reset LED light is on, it indicates it isin ON mode. Press “RESET” button and hold for 2seconds the Reset light will turn off and Auto Reset function is in OFF mode.When the Reset light is off, it indicates the Resetfunction is in manual mode. Press the “RESET”button once to enable manual Reset function.(3) Verify the condition of the unit and sensor• Set the sensitivity level to “Hi”.• Open the leak check bottle cover and slowlymove it closer to snake tube nozzle.• If the indication moves up to high from low thenwe should move the check bottle away and theLED should go off again. This shows that the unitis under working condition.• If the unit does not perform as we expect, bringthe unit for maintenance at your local salesoffice.(4) Enter the measuring mode• Place the tip of the leak-detector probe as closeas possible to the site of the suspected leak. Tryto position the probe within 1/4 inch (6 mm) ofthe possible leak source.• Slowly move the probe past each possibleleakage point.• When the instrument detects a leak source, theaudible tone will alarm. Additionally, the visualindicators will light from lower to higher; GreenLED then Orange LED then Red LED (highestconcentration) as increasing of level indicate thatthe location is close to the source.When the Instrument signals a leakage, pull the probe away from the leak for a moment, then bring it backto pinpoint the location. If the refrigerant leak is large, setting the sensitivity switch to LOW will make it easier to find the exact site of the leak.• Return the sensitivity switch to HIGH beforesearching for additional leaks.• When you’ve finished leak-testing, turn OFF theinstrument and store it in a clean place, protectthe leak detector from possible damage.SPECIFICATIONDetectable Gases : R-134a, R-404A, R-407C, R-410A, R-22 etcSensitivity :H M LR-22,134a 3g/year 15g/year 30g/yearR-404A, 407C, 410A 4g/year 20g/year 40g/yearAlarm Method : Buzzer, Tricolor LED bar Indicator Power Usage : 2 C size (3V DC) Alkaline BatteriesSnake Tube length : 40cm ( 15.5” )Dimension / Weight : 222 x 66 x 51 mm ( approximately 418g )Accessories : Alkaline batteries (C size) X 2 pcs User manual, leak check bottle, carry case, AC Adapter Battery Life : Approximately 16 hours normal use.Auto power OFF: 10 minutesDisable Auto Power Off : Press and Hold “Hi” button then power on the meter.Warm-Up Time : Approximately 45 secondsOperating Temperature & Humidity : 0 ~40 °C, < 80% RH Storage Temperature & Humidity : -10 ~60 °C, < 70% RH Altitude : < 2000M (6500’)� - EMC: Conforms to EN61326-1.This product complies with requirements of the following European Community Directives: 89/ 336/ EEC (Electromagnetic Compatibility) and 73/23/ EEC (Low Voltage) as amended by 93/ 68/ EEC (CE Marking).
