Basic Operation
Preparation
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.
Check the battery polarity carefully when inserting the batteries.
Be sure to dispose of used batteries properly.
1. Remove the battery cover.
2. Insert the batteries into the battery compartment.
WARNING
Do not attempt to measure DC voltage exceeding 50V. 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 be applied to the low voltage battery, which is
dangerous.
Test Leads
Two sets of test leads are supplied with the meter. Both sets provide 4 terminal Kelvin
connections which eliminates lead resistance and probe contact resistance from the
measurement. Use of either the alligator or press-probe is determined by the measurement
application.
