CT-2000型涡流测厚仪

一、概述

CT－2000 型涡流测厚仪(膜厚仪，涂层测厚仪，镀层测厚仪)是一种小型便携式仪器，用于测量有色金属基体上的非导电涂层的厚度，如铜、铝、锌等基体上的油漆、塑料、橡胶等涂层，或者是铝基体上的阳极氧化膜厚度等。该仪器采用涡电流测量原理，符合国际标准ISO2360和国家标准GB4957。

该仪器设计时曾参照国外的同类仪器，与国外仪器性能相同，功能相似。

采用红宝石耐磨触点的恒压导套式探头，可在各种坚硬、粗糙表面上得到稳定的输出。

该仪器具备以下几种重要功能：

1、校准数据关机保留功能：即开机时不必重新校准，关机后，校准数据仍可保留。

2、数据统计功能：可输出5种统计参数。

3、节电功能：停止测试3分种，仪器自动关机。

4、电池欠压指示功能：电池电压过低自动关机。

5、蜂鸣音提示功能：蜂鸣音提示有效测量、故障及误操作。.

三. Keyboard instruction

1. ON/OFF---

2.RES—Statistics Output key. Press this key five times, will get a group of measure

statistics result in sequence.

3.DEL—delete. It could delete the last one measured value.

4. CAL/ENTER—calibration key. Used in adjust instrument.

5.▽－Show value downward adjust.. It used in turn down the show value when operating adjustment. And it could cooperate with DEL to cancel the buzzer sound and recover the buzzer sound.

6.△－Show value up adjust key. It used in turn up the show value when operation adjustment.

四.Measurement operation

1. Press On/OFF. Connect instrument power. Instrument will begin to operate

self-check program. All the character in the displayer will appear at the same time and flashing one time, then send out buzzer sound, display 0. It means the instrument operating normally and in measurement status. For the instrument which had calibrated and calibrated recently, now it could going on measure operation. For the instrument which didn’t calibration for a long time, We could check the instrument precision by the standard Matrix.

2. Measuring method as follow: Put the probe steadily and vertical to the clean, dry, and flat test sample, instrument will buzzer, in the same time, it will show out coating thickness. It means once measurement finish. Uplift the probe, drop down again, and go on the next measurement. It could finish one group measurement after repeat 5-10 times.

3. Press RES 5 times and it could get one group of statistics data in sequence.

MEAN－平均值mean value

MAX－最大值maximum

MIN－最小值minimum

N－测量次数measure times

S－标准偏差standard deviation

Above English sign will showing on the right of displayer in sequence.

During the Statistic displaying, it could measure next group at any time, the new measurement will delete the ex-measure statistical result.

4.During measuring process, it will display an obvious wrong result if the probe laying unstable. We could press DEL to delete this value in order to avoid it effect the result veracity.

5. Measurement end, press ON/OFF, close the power for save electricity. This instrument has auto power-off function. It will auto power-off after stop operation 3 mins.

6. The instrument has battery voltage instruction function. When the battery voltage is insufficient, it will show "LOBAT" character. In the mean time, we should finish measure in 30 minute and change battery.The instrument has battery storehouse, open positions, replace the battery is ok.
