The Tektronix A6901 Ground Isolation Monitor. | [[File:A6901.jpg | thumb | 350px | right]] | ||
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. | |||
