Overview
UT12B is intended to check for the presence of
AC voltage, signaling the user with a beep and a
flashing LED.
Do not use the unit if it is wet, damaged or
cannot operate correctly.
Do not apply more than the rated voltage
between the probe tip and earth ground.
When the unit working at voltage over 30V in
AC, special care should be taken for there is
danger of electric shock.
Follow the local countries safety requirements
and standards.
Warning
This unit is only designed for the specialist
who has certain technical knowledge to use.
This unit is intended to check for the presence
of AC voltage, the voltage range is 90~1000V.
Make sure the tested inductor possible
voltage range before carrying out checking.
When you cannot sure the tested inductor
voltage range, the unit does not have any
response. It does not mean the tested inductor
does not have dangerous voltage, do not use
any part of the body to touch the tested
inductor.
When carrying out checking, keep your fingers
behind the probe tip finger guards.

Turn the unit on by pressing the power button
once, the unit beeps and LED flashes two times.
When the unit is under standby mode, the LED
keeps flashing two times in every 1.5 seconds.
Place the probe tip on or near the circuit or unit
to be tested. Beep and flashing LED indicate
the presence of voltage (90VAC to 1000VAC).
To turn off the beeper, you could press the
power button once after turning on the unit,
then you will hear a beep sound indicating the
beeper is off. After the beeper is off, only LED
will flash during checking. This way could save
