TROUBLESHOOTING
DISPLAY PROBLEMS
If the display does not turn on:
•
Check the connection to the vehicle battery or pack.
•
The vehicle battery may be too low to power the analyzer (below
1 volt). Fully charge the battery and retest.
•
The analyzer’s 9-volt battery may need to be replaced. Follow
the directions in “Replacing the Micro700 Battery” and replace
the 9-volt battery (alkaline recommended).
•
If the analyzer detects computer or ignition noise, it will display
SYSTEM NOISE
. Verify that all vehicle accessory loads are off
and the ignition switch is in the OFF position. The analyzer will
automatically retest when the system noise is no longer
detected. If the
SYSTEM NOISE
message continues after
several retest attempts, disconnect the battery cables and retest.
•
Batteries that are very weak or that have just been charged may
have enough electrical activity to affect test results. Should this
occur, the analyzer will display
UNSTABLE BATTERY
and retest
when the battery has stabilized. Fully charged batteries should
stabilize quickly. Weak batteries should be fully charged, then
retested.
•
If troubleshooting does not solve the problem, call 800-776-1995
to obtain service. See “Patents, Limited Warranty, Service” for
more information.
•
If the analyzer does not power on when you press and hold the
MENU button, replace the 9-volt battery.
