Chapter 5 Maintenance
Replacement of Batteries
If symbol appears on the LCD screen during measurement, it indicates the total voltage of
batteries being lower than 6.8V. For ensuring measurement accuracy, it is necessary to replace the
batteries. Before the replacement, must take off the red and black testing lines from the measured
circuit and turn off the power of the meter. Loose the fixing screws of the cover by a standard
screwdriver, then remove the cover to take out all the old batteries, replacing them with the
7# batteries. Take care to put in the batteries as the polarity specified on the shell of the meter.
Put the cover as its origin. The meter must not be used until the cover of batteries being put
properly and locked in.
Replacement of Fuse
It must take off the red and black testing lines from the measured circuit and turn off the power of
the meter before replacement of fuse. It should only use fuse of the same model and the same
electric specifications. And the meter must not be used until the cover of fuses being put properly
and locked in.
Notes: generally, fuses will not be blown under the normal use of the meter. In case of blowing it is
necessary first to find out the reasons for the blowing and then take an account on the use of the
meter. Generally, blowing may attribute to:
●
Perform voltage measurement under the current measurement state.
●
Current exceeds range.
