Ensure the terminal connections are correct for that
particular measurement selection before starting any
measurement. To avoid damage to the device, do not
exceed the input limit.

Charging Battery
It is strongly recommended that you use the
specified 24-volt DC adapter included as an
accessory to charge the rechargeable battery.
1 Remove the test leads from the multimeter
and turn the rotary switch to
.
2 Plug the DC adapter into a power outlet.
3 Insert 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.
4 The 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%.
NO TE
For the battery charger, the main supply voltage fluctuations
must not exceed ±10%.

• 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).
U1253B Quick Start Guide
CAU TI O N
• 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.

Frequency and Frequency Counter
Measurements
Frequency Measurement
During AC/DC voltage or AC/DC current
measurements, you can measure the signal
frequency by pressing
at any time.
Frequency Counter Measurement
1 Set the rotary switch to
2 Press
.
to select the frequency
counter (
) function. The default input
signal frequency is divided by 1. This
allows signals up to a maximum frequency
of 985 kHz to be measured.
3 Connect the red and black test leads to
input terminals V (red) and COM (black)
respectively.
4 Probe the test points and read the display.
5 If the reading is unstable or zero, press
to select division of input signal
frequency by 100 (
will be shown on
the display). This accommodates a higher
frequency range of up to 20 MHz.
6 The signal is out of the U1253B frequency
measurement range of 20 MHz if the
reading is still unstable after step 5.
WA RN ING
• 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.
