The Ground Man Plus monitors can be used to control the grounding impedance of workstations, tools and machines. The grounding impedance of up to 3 connectors against hard grounding can be monitored.
The Ground Man Plus monitor can also check the wrist strap grounding of a person with a twin connector wrist strap/grounding cable.
Control of the ground impedance
The ground impedance is continuously controlled on three separate channels connected with three instruments. The alarm threshold can be set between 1-20 ohm. It is the same for all 3 channels. The measurement is indicated by green (= OK) and red (= error) LEDs and an acoustic alarm signal. The acoustic signal can be turned off.
Output signal
It provides a logical 5V output for further processing. When all outputs are in the limit and power supply is existing, the output signal is logically 0 otherwise logically 1.
Monitoring of personnel grounding
The Ground Man Plus monitor provides an additional control of personnel grounding by a twin conductor wrist strap/grounding cable plug. The monitor measures the voltage of the person and the resistance of the wrist strap.
