Programmable Grounding Resistance Tester

Specifications

Executive test in 40A/60A of UL60950-1
Test resistance range 0~510m ohm
Output current range 3.0~60.0A

Goal: check that all the touch accessible parts are properly connected to the protective earth connection.

Executive test in 40A/60A of UL60950-1

    The tester will first check whether the input power supply right connected to N, L,G automatically after power on and give the prompt information if any of misconnection            Constant current output with the stability of 1% prevents inaccurate test results induced by output supply voltage

     Waveform distortion is less than 1% with linear power amplifier.

      The tester satisfies the safety regulation criterion, which require the crest factor must be within the range between 1.3 and 1.5      

      Key lock, preventing operators from modifying test parameters

     Adopt 240*64 graphic dot matrix LCD ,displaying setting parameters and testing parameters strikingly, visually

        LCD contrast, buzzer volume, the retention time of PASS signal can be adjusted by keystrokes.

        50 memory groups, 30 steps per group

        Rectification circuit adopts RMS-DC converter, truly reflecting testers output current value

         Standard PLC interface, optional ports: RS232C, RS485, GPIB, USB

        Through PLC interface control eight memory groups. Level signal or contact signal can be selected as PLC test signal and if level signal selected, PLC high output level is 24V during the testing

        Calibration and prompt function. After 12 months use, tester can automatically give prompt information

n         Test results which maximum can be up to 9999 will be stored into the tester or sent to PC through RS232 interface
