VERIFYING THE TOOL CIRCUIT
15. Disconnect the monitor's tool cord from its metal
tool.
16. Clip the red test lead's mini grabber to the tool cord.

17. Wait for the monitor's tool LED to illuminate red and
sound its audible alarm.
18. Press and hold the Verification Tester's METAL
GROUND PASS test switch. The monitor's tool LED
will illuminate green, and its audible alarm will stop.
This verifies the tool circuit's impedance limit.

switch
19. Press and hold the Verification Tester's METAL
GROUND FAIL test switch. The monitor's tool LED
will illuminate red, and its audible alarm will sound.
This verifies the tool circuit's impedance limit.
20. Press and hold the Verification Tester's METAL
GROUND PASS test switch. Simultaneously, press
and hold the Verification Tester's EMI LOW test
switch. The monitor's tool LED will remain green,
and no audible alarm will sound. This verifies the
operator circuit's low EMI voltage limit.

EMI LOW test switches simultaneously
21. Press and hold the Verification Tester's METAL
GROUND PASS test switch. Simultaneously, press
and hold the Verification Tester's EMI HIGH test
switch. The monitor's tool LED will blink red, and its
audible alarm will sound. This verifies the operator
circuit's high EMI voltage limit.

22. Disconnect the red test lead from the monitor's tool
cord.
