  • High efficiency design, low power consumption.
  • All test leads included.
  • Calibrated to NIST standards.
  • 1 year warranty
Options:
  • HTT-1 Hipot Operation Checker
  • Option HAN: Carrying Handle


  Description

The GFM-40AC is designed to meet the latest requirements of UL 60950 third addition for Protective Earthing and Protective Bonding Conductors where up to 40 amps may be required. Ideal for Product Safety and Design Engineers. The front panel allows adjustment of the AC current up to 40 amps. The meter displays both current output through, and voltage across, the grounding circuit of the unit under test.

The V=IRtual voltage sense circuit compensates for any resistance in both the test leads and AC power cord, eliminating the need for special cables.

Provided with cables, manual, and calibration certificate.

  Specifications

Electrical
Output 5-40 Amps AC into NEMA 5-15R receptacle for loads between 0 and 100mO.
6V Maximum Open-Circuit Voltage
Current is developed between the Grounding Pin of the NEMA Receptacle and the RETURN jack on the front panel of the GFM-30ac.
Meter Ranges Amperage (Top band): 0-40A
Voltage (Bottom band): 0-4V
Meter Range Selection Via front-panel switch.
