SERVICE AND
TROUBLESHOOTING
Service
There are only two service procedures that may be accomplished by the user: replacing the clock battery and replacing
the cable set. There are no other user serviceable items in the tester. The service can be accomplished in minutes and
the only tool required is a Philips head screwdriver.
Replacing the Clock Battery
The AA1000 and AA360 each contain a small battery to run the internal date and time clock. This internal battery has a
service life of 4 to 5 years. When this battery becomes low, the
(Internal battery low) icon will appear on the
screen whenever the display is active. The internal battery should be replaced. The battery is type: CR-2032 and is
commonly available.
To replace the internal battery:
1. Disconnect the tester from any external battery.
2. Remove the 4 screws on the back of the tester. The screws are located under the rubber feet.
3. Carefully lift and separate the back cover from the tester. The back cover will remain connected to the tester by a
short wire harness.
4. Using the tip of the screwdriver, remove the coin battery from the holder and install the new battery in the same
orientation, plus side (+) facing up.
5. Replace the back cover and re-install the 4 screws (do not over tighten) and reinstall the rubber feet.
The internal date and time must be re-set after replacing the battery.

To replace the cable set:
1. Disconnect the tester from any external battery.
2. Remove the 4 screws on the back of the tester. The screws are located under the rubber feet.
