MAINTENANCE
1
Battery replacement
If the symbol appears on the display, it is necessary to replace all batteries by
new ones of the same type (6 x 1.5 V AA, alkaline).
Proceed as following:
• Turn the impedance tester off (FUNCTION selector set to OFF) e take off the test
leads from the unit.
• Unscrew the four central screws of the rear cover (but not the four screws on the
corners) by using a screwdriver, remove the rear cover and replace the batteries
(note: pay attention to the polarity).
• Re-mount the rear cover and fix it with the four screws.

Cleaning and storage
Periodically wipe the impedance tester by using a soft dry cloth; do not use solvents
or abrasive substances to clean it.
After ending all impedance tests, always store the tester in its bag.
If the tester is not to be used for a period longer than 30 days, remove all batteries
and store them separately.
Keep this instrument far from dusty environments and water, which may damage
the tester or cause a short-circuit or be dangerous for the user.
