Tester Operation
Turning The Tester On
Press the Power On/Off button for less than 1s to turn the tester On. The tester
will beep twice, and will light a steady Green LED in the tip of the tester to indicate
Power On. The High Voltage Sensing Mode will be activated (Default Range) and
indicated by lighting a steady Red Dual Voltage Range Indicator Light.
Steady Green LED in the tip
indicates power-on
Dual Voltage Range Sensing
Short presses on the power button toggles the voltage sensing range between 50
to 1000V AC and 12 to 1000V AC. The tester defaults to the High Voltage Sensing
Mode (50 to 1000V AC) when the unit is turned on and is indicated by a steady Red
Indicator Light. Pressing the Power button for less that 1s will switch the tester to
the Low Voltage Sensing Mode (12 to 1000V AC) and is indicated by a steady Blue
Indicator Light.
Turning The Tester Off
Press the Power On/Off button for more than 1s (>2s for the 61-657) to turn the
tester Off. Listen for a long steady beep (~.5s) and watch for LED in the tip to turn
off and for the Range Indicator Light to turn Off. The tester is now deactivated and
is not operational.
