Trouble Shooting

If the instrument fails to operate, check batteries and test leads etc., and replace as

necessary. Double check operating procedure as described in this user's manual.

If the instrument voltage-resistance input terminal has been subjected to high voltage

transient (caused by lightning or switching surge to the system) by accident or abnormal

conditions of operation, the series fusible resistors will be blown off (become high

impedance) like fuses to protect the user and the instrument. Most measuring functions

through this terminal will then be open circuit. The series fusible resistors and the spark

gaps should then be replaced by qualified technician. Refer to the LIMITED WARRANTY

section for obtaining warranty or repairing service.

Cleaning and Storage

Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or

solvents. If the meter is not to be used for periods of longer than 60 days, remove the

batteries and store them separately.

Battery replacement

The meters use standard 3V alkaline button battery (ANSI/NEDA-5004LC, IEC-CR2032).

In models ACD-10 PRO & ACD-10 TRMS PRO, one battery are used.

Loosen the two screws from the case bottom and remove the bottom case. Slide the

battery out the side of the holder and replace with a new battery (observe polarity).

Replace the bottom case. Re-fasten the screws.
