• Perform battery charging only with 7.2 V or 8.4 V NiMH
rechargeable battery, 9 V size.
• Disconnect test leads from all the terminals when charging
the battery.
• Ensure proper insertion of battery in the multimeter, and follow
the correct polarity.
Use the specified accessory, the 24 V DC
adaptor to charge the battery.
1 Remove and disconnect the test leads from
the meter.
2 Turn the rotary switch to the
position. Connect the power cord to the DC
adapter.
3 Plug the Red (+)/ Black (–) banana
terminals of the DC adapter to the
and the COM terminals respectively. The
DC adaptor can be replaced with a DC
power supply in order to set the 24 V DC
output and the over current limitation to a
value more than 0.5 A. Ensure that the
polarity of the connection is correct.

the ‘SbY” flashes on the secondary display
and a short tone sounds to remind you
whether to charge the battery or not. Press
to start charging the battery, or the
meter will automatically start the self-test
after the 24 V supply is applied. We
recommend not to charge the battery if its
capacity is over 90%.
