4. MAINTENANCE
4.1 Battery Replacement
To avoid shock or injury, disconnect the electrical tester from
any external circuits and remove the test leads before proceeding.
The battery compartment is underneath the unit.
To gain access, undo the 2 screws securing the battery
compartment cover, then lift off the cover.
Fit a new 9V, PP3 alkaline battery (IEC 6LR61, NEDA 1604A).
Replace the battery cover and the 2 screws.
4.2 Test Lead Replacement
If the test leads become damaged they should be replaced.
The replacement test leads must have the same (or better)
overvoltage category rating as the TL17 leads supplied.

To maintain the integrity of measurements made using your
instrument, Martindale Electric recommends that it is returned
at least once a year to an approved Calibration Laboratory for
recalibration and certification.
