7.9 Data Hold

Under data hold mode, The LCD screen will only show the last saved measured voltage
value. No auto refresh of LCD screen reading under Data Hold mode whether the voltage
tester is connected to energized or non-energized circuit. The LED voltage indicators will
always show the actual voltage of the circuit under measurement.
•
After pressing the Torch Light push button for more than 2 seconds, the data hold function
is activated and replies with a short sound. The LCD screen shows "the last measured
value" and symbol "HOLD". The hold function can be deactivated manually by pressing the
Torch Light push button again. Function deactivation will be announced with a short sound.

8. Battery Replacement

Remove the probes from any testing point, when opening the Battery case. Batteries are
empty when the continuity test with both test probes connected cannot be done anymore. A
battery symbol in the LCD indicates low battery.
Follow the procedure below and replace batteries with new ones (type IEC LLR03 1.5V).
•
Unscrew the battery door using Philips type screwdriver.
•
Pull out the Battery door and replace the batteries. Insert new batteries according to the
engraving on the Battery door.
•
Re-assemble battery door.
Confirm that the Battery door case is properly locked prior to measurements.
