Recommended minimum span will hold noise within accuracy specificationwith damping at zero seconds.(2)Digital accuracy: digital output can be accessed by the Field Communicator.(3)Enhanced accuracy can be ordered using the P8 Model Code.(4)Total Analog accuracy is the sum of digital and D/A accuracies.(5)Applies to HART/4–20 mA devices.(6)Total digital accuracy for thermocouple measurement: sum of digital accuracy +0.25 °C (0.45 °F) (cold junction accuracy)(7)Digital accuracy for NIST Type B is ±3.0 °C (±5.4 °F) from 100 to 300 °C (212 to 572 °F).(8)Digital accuracy for NIST Type K is ±0.50 °C (±0.9 °F) from –180 to –90 °C (–292 to –130 °F).Reference accuracy example (HART Protocol only)When using a Pt 100 (α = 0.00385) sensor input with a zero to 100 °C span: Digital Accuracy would be ±0.10 °C, D/A accuracy would be ±0.02% of 100 °C or ±0.02 °C, Total = ±0.12 °C.Differential capability exists between any two sensor types (dual-sensor option)For all differential configurations, the input range is X to Y where:■X = Sensor 1 minimum – Sensor 2 maximum and■Y = Sensor 1 maximum – Sensor 2 minimumDigital accuracy for differential configurations (dual-sensor option, HART Protocol only)■Sensor types are similar (e.g., both RTDs or both T/Cs): Digital Accuracy = 1.5 times worst case accuracy of either sensor type ■Sensor types are dissimilar (e.g., one RTD, one T/C): Digital accuracy = Sensor 1 accuracy + Sensor 2 accuracyAmbient temperature effectTransmitters may be installed in locations where the ambient temperature is between –40 and 85 °C (–40 and 185 °F). To maintain excellent accuracy performance, each transmitter is individually characterized over this ambient temperature range at the factory.

These values can also be configured in the field using a Field Communicator.Transient protection (option code T1)The transient protector helps to prevent damage to the transmitter from transients induced on the loop wiring by lightning, welding, heavy electrical equipment, or switch gears. The transient protection electronics are contained in an add-on assembly that attaches to the standard transmitter terminal block. The external ground lug assembly (code G1) is included with the transient protector. The transient protector has been tested per the following standard:■IEEE C62.41-1991 (IEEE 587)/location categories B3. 6 kV/3 kA peak (1.2 x 50 μS Wave 8 x 20 μS combination wave) 6 kV/0.5 kA peak (100 kHz ring wave) EFT, 4 kV peak, 2.5 kHz, 5 x 50 nS■Loop resistance added by protector: 22 ohmsmax.■Nominal clamping voltages: 90 V (common mode), 77 V (normal mode)Local displayOptional five-digit LCD display includes 0–100% bar graph.

An independent circuit is designed to provide backup alarm output if the microprocessor hardware or software fails.The alarm level is user-selectable using the failure mode switch. If failure occurs, the position of the hardware switch determines the direction in which the output is driven (HIGH or LOW). The switch feeds into the digital-to-analog (D/A) converter, which drives the proper alarm output even if the microprocessor fails. The values at which the transmitter drives its output in failure mode depends on whether it is configured to standard, or NAMUR-compliant (NAMUR recommendation NE 43) operation. The values for standard and NAMUR-compliant operation are as follows:Table 9: Operation Parameters(1)Measured in milliamperes.Load limitationsMaximum load = 40.8 x (Supply voltage - 12.0) without transient protection (optional).1.HART® and analog operating range2.Analog only operating rangeNoteHART Communication requires a loop resistance between 250 and 1100 ohms.

SPM technology calculates the mean and standard deviation of the process variable and makes them available to the user. This may be used to detect abnormal process situations. The thermocouple diagnostic enables the transmitter to measure and monitor the resistance of thermocouple loops in order to detect drift or changing wiring connections.Sensor drift alert allows the user to monitor the difference in measurement between two sensors installed in one process point. A change in this differential value may indicate drifting sensors.Local displayDisplays all DS_65 measurements in the Transducer and Function Blocks including Sensor 1, Sensor 2, differential, and terminal temperatures. The display alternates up to four selected items. The meter can display up to five digits in engineering units (°F, °C,°R, K, Ω, and millivolts). Display settings are configured at the factory according to the transmitter configuration (standard or custom). These settings can be reconfigured in the field using a Field Communicator or DeltaV. In addition, the LCD display provides the ability to display DS_65 parameters from other devices. In addition to the configuration of the meter, sensor diagnostic data is displayed. If the measurement status is Good, the measured value is shown. If the measurement status is Uncertain, the status indicating uncertain is shown in addition to the measured value. If the measurement status is Bad, the reason for the bad measurement is shown.NoteWhen ordering a spare electronics module assembly, the LCD display transducer block will display the default parameter.Turn-on timePerformance within specifications is achieved less than 20 seconds after power is applied to the transmitter when the damping value is set to zero seconds.StatusThe device is compliant to NAMUR NE 107, ensuring consistent, reliable and standardized device diagnostic information.The new standard is designed to improve the way device status and diagnostic information is communicated to operators and maintenance personnel in order to increase productivity and reduce costs.If self-diagnostics detect a sensor burnout or a transmitter failure, the status of the measurement will be updated accordingly.

7.6 进行回路测试Loop Test （回路测试）检验变送器输出、回路完整性、回路中安装的记录器或相似设备的运行情况。
启动回路测试：a、将外部安培表与变送器回路串联（这样变送器的电源电流才能在回路中的某一点通过安培表）。
b、在Home screen （主屏幕）中，选择1 Device Setup （1 设备设置）、2 Diag/Serv （2 诊断/ 维修）、1 Test Device （测试设备）、1 Loop Test （1 回路测试）。
通信器显示回路测试菜单。
c、为变送器输出选择一个合理的毫安级。
在Choose Analog Output （选择模拟输出）中选择1 4mA、2 20mA 或选择4 Other（其它），手动输入 4 和 20 mA 之间的一个值。
