TEST
• Because of the time required for the PI and DAR tests, alligator clips are recommended.
• Use rotary selector dial to select desired test voltage.
• The display will show “----” until test starts.
• The High Voltage symbol will display if greater than 30V AC or DC is present.
• Press and release the Test Button on the Meter or Remote Probe to start the test.
Note:
When the resistance is higher than the maximum display range the tester displays the > symbol and the maximum
resistance for the range.
WARNING
NEVER measure resistance on a live circuit.
