9. Cleaning and storage
Tester does not need any special maintenance
if used according to user manual.
Remove tester from all test points before
cleaning.
Use a lightly damp cloth with neutral detergent
for cleaning the instrument. Do not use abrasives
or solvents.
Do not expose the instrument to direct
sun light, high temperature and humidity or
condensation.
Remove batteries when the instrument will not
be in use for a long period.
7. Battery replacement
Remove the probes from any testing point,
when opening the battery case.
Short the probe tips before any testing to
verify battery status.
Voltage level detection is possible without batteries
but the buzzer and the single pole LED will not
operate.
Follow the procedure below and replace
batteries with new ones (type IEC LR03 /
AAA 1.5V).
• Unscrew the battery case, with a screwdriver.
• Pull out the battery case and replace the
batteries. Insert new batteries according to the
engraving on the battery case.
• Re-assemble battery case.
Confirm that the battery case is properly
locked prior to measurements.
