Vsense test
This test is for U1192A, U1193A, and U1194A models only. Use the following
procedure to verify that Vsense is functional.
NOTE
– Keep the clamp meter away from electrical noise sources (that include
fluorescent lights, dimmable lights, motors, and so on) during the tests.
These sources can trigger the Vsense alert and invalidate the test.
– It may be necessary to slightly adjust the clamp meter’s position for
maximum signal strength, in order to get the clamp meter’s beeper to sound
continuously.
CAUTION
Do not touch the dual banana plug with your hand while the calibrator
output is turned on.
