8.0 MAINTENANCE

8.1 Battery Replacement

When the battery low icon is on, the battery should be replaced as soon

as practical. The testing results will become unreliable when the battery

reaches about 5.0 volts. To replace the battery:

Be sure tester is off.

Remove rubber battery cap by pressing on edge of the cap with the

heel of the hand until the cap pops off.

Pull battery out of cavity and remove battery snap.

Connect a new Alkaline 9 volt battery to battery snaps within one

minute.

Slide battery into cavity and snap cap in place.

To preserve user set data, the unit must be off and the battery

disconnected for no more than one minute.

8.2 To Reset the processor

All user data will be lost.

Turn on tester in any mode.

Remove battery cap and disconnect battery.

Wait about 10 seconds and reattach battery leads. Length screen will

appear briey, than tester will shut down.

When installing a new battery or resetting the processor, disconnect

any cables connected to the tester. The length and single-ended test

modes will be improperly calibrated if a cable is present when the battery

is connected.
