6. Replacing the battery
When the electrical tester displays the “ ”
mark, the battery must be replaced to avoid incorrect
measuring data. Use the following procedure to
replacing the battery:
1. The power key is used to select “O” ( OFF ).
2. Opening the battery cover by a piece coin.
3. Remove the exhausted battery and replace with
two new 1.5V AAA batteries.
4. Place battery cover and secure.
WARNING
To avoid electric shock, make sure that the test
leads have been clearly move away from the
circuit under measurement before opening the
battery cover of the meter.
WARNING
Do not mix old and new batteries. Do not mix
alkaline, standard (carbon-zinc), or rechargeable
(ni-cad, ni-mh, etc) batteries.
