Summary

CS9950DS type programmable grounding resistance tester, adopts microcomputer controller to control the size of the output current and output current frequency;Tester output is constant current source output. the output current is within the scope of the tester , the size of the output current does not change along with the change of external load resistance, the output current value is set current value;Having open alarm function, equipped with PLC for signal input and output interface, easy to integrated test system with PLC, can also be equipped with RS232 interface, can accurately measure its resistance value of between all kinds of motors, electrical appliances, instruments and meters, household appliances, and so on the power supply of electrical equipment enclosure accessible metal parts and the protective earthing terminal.

1.constant current output: the output current stability factor range within 1%, avoid the unstable input power supply voltage and load change and make the output voltage change, the measured results is not accurate.

2. open circuit alarm function.

3. four-terminal method is used to measure and eliminate the influence of contact resistance.

4.set low resistance deviation.

5.with resistance upper limit and lower limit alarm function, avoid to be measured by test line open circuit when a wrong result;

6. set parameters with functions of power lost memories.

7.With functions of keeping low test parameters.

8.preset: save the test parameters can be set up to 30 files, each file can be set up 99 test step.

9.With the keyboard lock, protect the test parameters by the operating personnel changes.

10.Front panel calibration software, without opening the parameter calibration can be made.

11.Interface PLC, optional RS232C, RS485, USB, GPIB interface.

1. Safety electric protection wall and safety protection system, can protect the safety of operator, ensure test pieces are not damaged.

2. standard sine wave generated by DDS, linear power amplifier drive output, output current waveform distortion degree, small pure, is better than 2%.

3. automatically keep the test results within the tester, making it easy for users to check test results;Can also be connected to the RS232 interface of the test results into EXCEL spreadsheet for data statistics, analysis (CS9950CX).

4.PLC interface test signal can be output 24 v level, can also be output contact (CS9950CX).

5.List function, when the test step is greater than 2, after testing, the tester can automatically display (CS9950CX) every step of the test result.

1. Household electrical appliances, television sets, refrigerators, air conditioners, washing machines, dehumidifiers, electric blanket, charger, etc

2.Instruments: oscilloscope, signal generator, dc power supply, switching power supply, etc

3.The low lighting, ballast, road lights, stage lights, lantern and other kinds of lamps and lanterns

4.Electric heating appliance: electric drill, ShouQiangZuan, cutting machine, grinding machine, grinding machine, welding machine, etc

5.electrical machine such as: . motor rotating motor and so on

6. office equipment: computer, counterfeit detector, printer, copier, etc
