Troubleshooting the Display
If the display does not turn on:
• Check the connection to the vehicle battery.
• The vehicle battery may be too low (below 1 volt) to power the ana-
lyzer. Fully charge the battery and retest.
• The analyzer’s 9-volt battery may need to be replaced. Follow
the directions in “Replacing the 9-Volt Battery” and replace the
9-volt battery (alkaline recommended).
• If the analyzer does not power on when you press and hold the
MENU button, replace the 9-volt battery.
Replacing the 9-Volt Battery
The tester uses a 9-volt battery (alkaline recommended) that allows test-
ing of 12-volt batteries discharged down to 1 volt in addition to supply-
ing power while the option menu is active. The tester can test down to
5.5 volts when the internal 9-volt battery is not functioning.
NOTE: The tester retains setup information while you change the 9-volt
battery.
1. Turn the tester face down.
2. Remove the screw securing the battery compartment cover using a
small Phillips screwdriver.
