4.2 Maximum Value Measuring And Hold
At the range of voltage, you can put on "MAX.H"
button, it will hold the maximum value; if you put the
button again, the maximum value will not be held.
4.3 Function Transform
Put down the "FUNC." button when measuring the voltage.
Meter will be transformed between DC and AC range.
Put "FUNC." button when measuring the resistance,
diode and continuity, meter will transform among them.
4.4 Range Transform
The auto range is used when measuring the voltage and
resistance. Put down the "RANGE" button if the manual
range is needed. Each time you put down, range will go
upward; the minimum range is transformed if "RANGE"
is put down at the maximum range. If the "RANGE" button
is put down more than two seconds, auto range is used again.
4.5 Auto Power Off
If there's no any operation within fifteen minutes after
power is on, meter will auto power off with five short
sounds and a long sound in a minute.
After auto power off, if stir the transform switch or put
down any button of "FUNC.", "MAX.H", "RANGE",
meter will recover the working condition.
If presses the "DATA-H" button when power is on,
auto power off disable. In sleep mode, the auto power
off function will be cancelled if presses the "DATA-H"
button to wake the meter.
4.6 Preparation For Measurement
4.6.1 Set the transform switch to the right range. At the
manual range, when the value scale to be measured
is unknown beforehand, select the highest range.

4.6.2 When measuring, at first, connect to the public (COM)
testing line, then connect the probe tip of the meter to
the circuit under test.
4.6.3 If the battery voltage is less than 2.4V, display will show
"
", the battery should be changed at this time.
4.7
Measuring
DC Voltage
WARNING
Risk of Electrocution.
You can't input the voltage which is higher than
600V DC, it's possible to show higher voltage,
but it may damage the inner circuit or cause
electrical shock.
Pay attention to avoid getting an electric shock
when measuring high voltage.
4.7.1 Rotate the probe socket clockwise to spin out the
probe from the meter.
4.7.2 Insert the black test lead or test clip in the COM jack.
4.7.3 Set the transform switch at the V
4.7.4 Press the "FUNC." Button to transform to DC
measurement. Auto range and manual range can be
transformed by pressing the "RANGE" button.
