If the test leads are not shorted properly or become accidentally disconnected

during this process, auto-zero will fail and you should hear a long beep before the

display returns to the impedance measurement screen. In this case you will need

to repeat this process again.

Voltage Measurements

The presence of voltage on a ground is never desirable.

The 3M

Ground Pro Ground Integrity Meter can measure

™

both AC and DC voltages on a ground.

AC Voltage

Press the V button once. The Ground Pro

will switch to AC voltage measurement

mode and you should see a screen similar

to one on the right. You can adjust the

measurement scale using the Up and Down

arrow buttons.

DC Voltage

Press the V button again to switch to DC

voltage measurement mode. You should see a

screen similar to the one on the right. As in AC

mode, you can adjust the measurement scale

using the Up and Down arrow buttons.

Overload

If voltage on the ground is above the maximum

level on a particular scale, you should see an

overload indicator such as the one on the right.

In such a case, go to the next scale using the Up

arrow button.
