8. MAINTENANCE
Before replacing batteries completely disconnect the device from all external
power circuits. For transportation and maintenance purposes it is recommended
that the Range Selector switch be set to the OFF/ V position, in order to prevent
unintentional activation.
8.1 Batteries
Batteries should be checked. Discharged or corroded batteries must be removed
from battery compartment. If leakage occurs at batteries, battery electrolyte must
be completely removed and batteries replaced.
Batteries must be replaced when:
• pointer no longer points within battery symbol range of dial when Range
• green LED for selected test voltage does not light.
Replace batteries as described in paragraph 4.1.
8.2 Housing
No special maintenance is required for the housing. Keep outer surfaces clean
and dry. Use a damp cloth for cleaning. Avoid use of cleansers, abrasives or
solvents. Make sure housing is thoroughly dry before using tester.
8.3 Measurement Cables
Damaged or buckled measurement cables may not be used under any circum-
!
Selector switch is set to battery test position.
