Replacing the Battery
Replacing the Battery
CAUTION
• Before replacing the battery, always disconnect the tester from the
measurable conductor under test because there is a risk of electri-
cal shock. After replacement, close the battery cover securely and
conduct measurements.
• Use the specified lithium battery (CR2032).
To replace the battery:
a) Press the POWER switch to turn off the power.
b) Turn the battery cover on the backside of the instrument in the direction
of the arrow using a coin, etc.
c) Remove the cover and the battery.
d) Insert a new battery, making sure that the polarities are correct.
e) Close the cover back in place by turning it in the reverse direction of the
arrow.

Close the battery cover, aligning
the arrow's tail with the dot and
then turn clockwise.
Insert the battery being careful
that the polarities are correct.
