MULTIMETER

The Multimeter function lets you quickly check a battery's voltage, and, with optional
amp probes, lets you test the electrical current for the ranges of 1 mV/Amp,
10 mV/Amp, and 100 mV/Amp.

4.1 - Pretest Steps
To prepare for multimeter testing, do the following:
1. Check the following:
If the battery being tested is frozen, let it warm up before testing.
Make sure that the terminals of the battery being tested are clean and dry;
brush and clean gently if necessary.
If the battery being tested was recently charged or used (is in a vehicle that
had the engine running), let the battery stabilize 3 minutes before testing.
Otherwise, let the battery stabilize 1 minute before testing.
If testing a battery installed in a vehicle, make sure the contact between the
battery terminals and cables is not oxidized or loose, which causes cranking
and charging problems and may falsify the test results.
If testing a battery installed in a vehicle, turn off all sources that may drain
current from the battery. For example, turn the vehicle's ignition key and all
accessories and other loads off, close the doors and trunk, and disconnect the
under-hood light.
NOTE:
For dual battery systems, test the batteries individually. First disconnect one and test
the other, then repeat for the other battery.
2. Install a 9-volt battery in the tester's battery compartment (to open the
compartment, slide the cover toward the bottom of the tester).
3. Connect the test lead (the one with the battery clamps) to the test lead port on the
top of the tester. Finger-tighten the connector's screws.
4. Insert the amp probe's lead pins into the jacks on the top of the tester; black pin
to black jack, red pin to red jack.
NOTE:
Use only the amp probes described in this manual; do not use the jacks for any other
leads.
