• Default =
TEST
• The display will show “----” until test button is pressed.
• The High Voltage symbol will display if greater than 30V AC or DC is present.
• Press and hold the
TEST button
on the Meter or Remote Probe to start the test. Test stops when
TEST button
is released.
• Keep test leads on test points after
TEST button
is released. The circuit under test will then discharge.

Note
:
When the resistance is higher than the maximum display range the tester displays the > symbol and the maximum
resistance for the range.
WARNING
Do not measure resistance on a live circuit.
