MEWOI-ZUHL Micro Ohm Meter 100A 200A Contact Loop Resistance Tester Contact Resistance for Testing HV Breaker switchgear

INTRODUCTION

MEWOI-ZUHL Series Intelligent Loop Resistance Tester is made and contained of advanced high-power switching power supply technology and advanced electronic circuit. It is the dedicated tester for the resistance of high and low switch, cable wire and welding joint. Its current uses national standard GB736 recommended standard DC, can measure the resistance value of being tested object under standard current status. The tester is small dimension, light weight, strong anti-interference, high precision, easy operation and perfect function protection and so on.

MAIN FEATURES

1. Color Touch Screen: 800*480 high resolution color 7’’ touch screen, user interactive interface, high-speed thermal printer.

2. Large-range current output: Adopt the latest power supply technology, long time continuously output big current, large-range current output. Can set 1 to 3 different current ranges for testing, and automatically calculate average value.

3. Digital displaying data information: Resistance, voltage, current, electrical resistivity, resistance values at converted standard temperatures.

4. Auto-alarm of over limit: Set resistance up-limit value of pass / over limit / invalid, automatically generate testing status.

5. Long-time testing: Can set test time from 0-9999s and support long-time working. Inside cold-wind heat dissipation, switch power automatically protection.

6. High-precision measurement: Use Operational amplifiers from precision instruments and High precision quadruple integral A/D converter.

7. Latest System IC: Use High performance 32-bit latest ARM chips, System automatically switch magnification times based on signal, ensure testing precision.

8. Inside Calendar & Clock: provide accurate time of testing and printing.

9. DC constant current source function: Can output current from 0 to infinite value, built-in current step-by-step up-flow test, equal to another powerful DC constant current source for test.

10. Large-volume testing record storage: Build-in large capacity storage for look up; also have data protection function while power shut down suddenly.

11. Removable USB flash drive data access: Expert excels file data record.

12. Standard Modbus-RTU: Build-in RS232 port (customized convert to RS485), communication protocol Modbus-RTU.

13. Computer control and upload test data: Build-in RS232 port for the data control, upload, generate word/excel file.

14. Blue tooth control and upload data: Standard configuration blue tooth function, build-in android BT APP for data control / upload / generate word file.

15. Convenient cable operating: Cable control mode (customized), set cable control switch to regulate open / touch, test / interruption, light-alarm for resistance output over limit.

16. Quick and convenient wireless remote controller: it is customized, with one button operation of testing and interruption, customized controller can show the test progress.

17. Temperature offset automatically calculates resistance: Can preset temperature, automatically calculate resistance in standard temperature. Also use temperature sensor (customized) to measure.

18. Background color change: Set background color to blue and graphic black, brightness, standby brightness and time.

19. Build-in training material: Document shows the cable connecting method for onsite guidance.

20. Chinese input test information: Key in test spot, equipment, person, remark etc, convenient to remark and store test data and printing.

21. Big current cable quick connection: Use latest big current cable port, insert and turn lock up.

22. Multiple-phase selection: Normal is single-phase, customized to be two-phase test and three-phase test simultaneously.
