The following safety information must be observed to ensure maximum personal safety during the
operation of this tester.
To avoid electric shock when replacing the batteries first disconnect the leads from the object
to be measured.
When replacing the batteries, do not install old batteries with new ones and do not mix
different types of batteries.
Check the battery polarity carefully when inserting the batteries.
Do not short circuit used batteries, disassemble them, or throw them in a fire. Doing so may
cause the batteries to explode.
Be sure to dispose of used batteries properly:
•Remove the battery cover
•Insert the batteries into the battery compartment
WARNING!
Do not attempt to measure DC voltage exceeding 60V. Do not attempt to measure AC voltages.
This could result in injury or damage to the unit.
Do not attempt to measure the voltage of a generator. This would result in an AC voltage being
applied to the voltage generating output terminals, which is dangerous.
After measuring a high voltage battery, before continuing to measure a low voltage battery first
short the measurement leads together. This will discharge the DC elimination capacitor which is
connected across the leads. Otherwise an excess voltage may applied to the load voltage battery.
