slide-switch to the OFF position and then slide back on again. Always set the slide-switch to the
OFF position manually when the meter is not in use.
5) Maintenance
WARNING
To avoid electrical shock, disconnect the meter from any circuit, remove the test leads from the
input jacks and turn OFF the meter before opening the case. Do not operate with open case.
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 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 and Fuse replacement
The meters use standard 1.5V alkaline button batteries (IEC/JIS LR44, GAP76, or V13GA).
In models BM111 & BM112, 2 batteries are used.
In models BM125 & BM126s, 4 batteries are used. 2 batteries are used for the slide-switch
functions, and the other 2 batteries are used for the dual display ACA function separately.
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.
