The '''Tektronix A6901 Ground Isolation Monitor''' connects between mains power and test equipment
without connecting protective ground, in order to safely allow referencing measurements to a low voltage
instead of ground, or break ground loops.
 
It monitors the floating equipment ground voltage. If the voltage exceeds 40 V peak,
or ground current exceeds a selectable limit of 0.5, 3.5 or 5 mA, the A6901 disconnects
mains power and grounds the test equipment.

The Tektronix A6901 Ground Isolation Monitor connects between mains power and test equipment without connecting protective ground, in order to safely allow referencing measurements to a low voltage instead of ground, or break ground loops.

It monitors the floating equipment ground voltage. If the voltage exceeds 40 V peak, or ground current exceeds a selectable limit of 0.5, 3.5 or 5 mA, the A6901 disconnects mains power and grounds the test equipment.
