Battery Test (Automatic)
CAUTION
Wear Safety Glasses, Do not break live circuits at the battery
terminals, Avoid ac ci den tal ly shorting the insulated battery
terminal to any ground metal. Never put a wrench on a live
battery wire terminal. Burns may be the result. Dis con nect
the battery chassis cable fi rst.
1. Be sure the Load Knob is turned to OFF.
2. Connect the analyzer Battery Clamps to the battery
ter mi nals; Red to positive, Black to negative.
3. With the Amp Probe jaws closed and not around any
wires, press the Zero Amps buttons until the Amps
Display shows “000”
4. Connect the Amp Probe around either analyzer load
lead.
5. Press the BATT button. The analyzer will measure the Open circuit voltage of the battery. When the analyzer
displays “LOAd” you should apply a load equal to 1/2 the Cold Cranking Amps rating.
6. Turn the Load Control Knob clockwise until the amps reading gradually reaches the required load.
7. When the Analyzer beeps, turn off the load. The analyzer will now measure battery recovery time and calculate
the Cold Cranking Amps rating of the battery.
8. At the conclusion of the test, a report will be printed.

Open Circuit Voltage Test
The open circuit (no load) stabilized voltage of the Battery.
An open circuit voltage of less than 12.4 volts indicates
the battery should be charged before testing.
Load On Time
The time, in seconds, that a load is being applied to a
battery.
Recovery Time
The time it takes the battery to recover from the loaded
voltage to 12.3 volts once the load is removed. Used to
calculate the CCA of the battery. If it takes more than
30 seconds to recover, the battery is weak.
CCA Estimate
The estimated Cold Cranking Amp rating of the
battery. Three readings are given based on the battery
temperature.
