10. RE PLACING THE BATTERY
To avoid e lectrical s hock or per so nal injur y,
remove th e te st leads an d any input sig nals
before re pl acing the b attery. Re place onl y
with same t yp e of batter y.
When the electrical tester displays the “ ” mark or
the backlight be not very lit, the battery must be
replaced to maintain proper operation. Use the
following procedure to replacing the battery:
1.T he Rotary Switch is used to select OFF. Disconnect
test leads from any live source and remove the test
leads from the input terminals.
2.R emove screws on the battery cover and open the cover.
3.R emove the exhausted battery and replace with a new
9-voltage battery (IEC 6F22 JIS 006P NEDA 1604 type).
4.N ever use the multimeter unless the battery cover is
in place and fastened fully.
