CHAPTER 1
INTRODUCTION
WARNING
These safety warnings are provided to ensure the safety of person-
nel and proper operation of the instrument.
• Do not attempt to perform any tests with this instrument until you
have read the user manual.
• Tests are to be carried out on de-energized circuits only! Never
connect the unit to a live circuit.
• When the unit is measuring resistance showing a high inductive
component (transformers, motors, etc.) after ending the measure-
ment, the unit then discharges the inductive sample and the
warning icon
appears for the entire duration. Never disconnect
the connection wires before this icon disappears.
• The micro-ohmmeter should never be used in an explosive
environment (this includes poorly ventilated battery rooms and
enclosures).
• Make sure the internal battery is fully charged prior to testing. If the
instrument has been left unused for several months, recharge the
battery.
• We recommend recharging the micro-ohmmeter every month to
ensure a full battery charge when used.
• When replacing fuses, install only fuses which are direct replace-
ments.
• If the case needs cleaning, do not use any alcohol or oil based
cleaners. Preferably use soapy water with a damp cloth or
sponge.
• The test leads and measuring wires must be in good condition and
should be changed if there is any evidence of deterioration (insula-
tion split, burnt, etc.).
• Never exceed the safety values indicated in the specications.
