Pen type multimeter
Auto Power Off
The meter has an auto power off
feature that will turn the meter off
automatically if left on. After approx.
14 minutes of non-use, the meter
will sound 5 short beeps and then 1
minute later the meter will sound 1
long beep and turn itself off.
After auto power off has occurred,
either move the rotary switch or
press
FUNC , MAX or RAN buttons to
turn the meter back on.
If you hold down the
HOLD button
when turning on the meter, this will
disable the auto power off function.
The auto power off function will re-
enable after the meter is turned off
again.
Preparing for
measurement
Select the desired function using the
rotary switch. If in manual mode,
select the highest range first if the
value to be measured is unknown
beforehand and lower as needed.
When connecting the meter to a
circuit, connect the common lead
first then the meter’s test probe.
lf the battery voltage becomes <2.4V,
the
symbol appears on the
display. Replace the batteries before
making measurements.
