Operating Features
Audible Notification Disable (61-637 Only)
The tester can be operated with a visual only indication of voltage when working in
noise sensitive/noise restricted areas. With the tester On, press the Speaker button
for less than 1s. The tester will beep once to indicate the audible warning is muted
and only a visual indication will be provided. To restore the audible warning, press
the speaker button for less than 1s. The tester will beep twice to indicate the audible
warning is active and both a visual and audible indication will be provided. The
tester is set to Audible Notification On as the default setting.
Flashlight (61-637 Only)
An LED Flashlight in the tip operates independently of the tester functions and can
be used to illuminate the work area. Press the Flashlight Button to turn it On/Off.
The tester is set to Flashlight Off. The Flashlight will Auto Power Off after 5 minutes
of no voltage detection. Further voltage detection will reset the APO function to 5
minutes again.
Note: Use of the flashlight will decrease battery life.
Auto Power Off
After 10 minutes of inactivity (no button pressed and no signals detected), the
tester will emit one long beep (~0.5s) and then shut off. Note: if the flashlight is on,
it will be also shut off.
Low Battery Indication
If battery voltage is less than around 2.4V, the green led in the tip will flash 3 times
and the buzzer will send out one long beep, then turn off the device.
