• Short the ends of the test leads together, press the
SELECT button
and wait until
ZERO
appears. The meter measures the
test leads resistance, stores the data/results in memory and subtracts it from the reading. The test lead resistance is saved
even after the meter is powered off.
• The display will show “----” until a valid resistance reading is detected.
• The High Voltage symbol will display if greater than 2V AC or DC is present. If the meter “chirps”when you press the
TEST button
, test is corrupted due to voltage being present.
• Press and hold the
TEST button
on the Meter or Remote Probe to start test. Test stops when the button is released.
