Charging the Battery
It is strongly recommended that you use the
specified 24-volt DC adapter included as an
accessory to charge the rechargeable battery.
1Remove the test leads from the multimeter
and turn the rotary switch to .
2Plug the DC adapter into a power outlet.
3Insert the red (+) and black (–) banana plugs
(4 mm plugs) of the DC adapter to the
and terminals respectively. Ensure that
the polarity of the connection is correct.
4The display will show a countdown timer of
10 seconds for the self-test to start. The
multimeter will output short single-tone
sounds to remind you to charge the battery.
Press to start charging the battery, or
the multimeter will automatically start

charging after 10 seconds. It is recommended
not to charge the battery if the battery
capacity is over 90%.
NOTE
For the battery charger, the main supply voltage
fluctuations must not exceed ±10%.
CAUTION
– 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.
– A new rechargeable battery comes in a
discharged condition and must be charged
before use (refer to the U1253B User's and
Service Guide for charging instructions).
– Upon initial use (or after a prolonged storage
period), the rechargeable battery may require
three to four charge/discharge cycles before
achieving maximum capacity. To discharge,
simply run the multimeter under the
rechargeable battery's power until it shuts
down or the low battery warning appears.
– The multimeter may indicate that charging is
complete after ten minutes when charging a
new rechargeable battery. This is a normal
phenomenon with rechargeable batteries.
Remove the rechargeable battery from the
device, reinsert it, and repeat the charging
procedure.

measurement range of 20 MHz if the reading
is still unstable after step 5.
WARNING
– Use the frequency counter for low voltage
applications. Never use the frequency counter on
AC power line systems.
– For input more than 30 Vpp, you are required to
use frequency measurement mode available under
the current or voltage measurement instead of
frequency counter.
