U1251B and U1252B Quick Start Guide

Charging the Battery

NOTE

For the battery charger, the mains supply voltage should not

fluctuate by plus or minus 10%.

CAUTIONCAUTION

• Do not rotate the rotary switch from position when

charging the battery.

• 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.

4 The primary display indicates “bAt” and

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%.
