OPERATION
WARNING
: Risk of electrocution. High-voltage
circuits, both AC and DC, are very dangerous and
should be measured with great care.
1.
ALWAYS turn the function switch to the OFF
position when the meter is not in use. This meter
has Auto OFF that automatically shuts the meter
OFF if 15 minutes elapse between uses.
2.
If “OL” appears in the display during a
measurement, the value exceeds the range you have
selected. Change to a higher range.
NOTE
: On some low AC and DC voltage ranges, with the
test leads not connected to a device, the display may show a
random, changing reading. This is normal and is caused by
the high-input sensitivity. The reading will stabilize and give
a proper measurement when connected to a circuit.

DATA HOLD AND BACKLIGHT BUTTON
The Data Hold function allows the meter to "freeze" a
measurement for later reference.
1.
Press the DATA HOLD button to “freeze” the reading
on the indicator. The indicator “HOLD” will be appear in
the display.
2.
Press the DATA HOLD button to return to normal
operation.
3.
Press the HOLD button for 2 seconds to BACKLIGHT
button it will turn on or off)
RELATIVE BUTTON
The relative measurement feature allows you to make
measurements relative to a stored reference value. A
reference voltage, current, etc. can be stored and
measurements made in comparison to that value. The
displayed value is the difference between the reference value
and the measured value.
1.
Perform any measurement as described in the operating
instructions.
2.
Press the RELATIVE button to store the reading in the
display and the "
REL
" indicator will appear on the
display.
3.
The display will now indicate the difference between the
stored value and the measured value.
4.
Press the RELATIVE button to return to normal
operation.
DC VOLTAGE MEASUREMENTS
CAUTION:
Do not measure DC voltages if a motor
on the circuit is being switched ON or OFF. Large
voltage surges may occur that can damage the meter.
1.
Set the function switch to the V DC position (“mV” will
appear in the display).
2.
Insert the black test lead banana plug into the negative
(COM) jack and the red test lead banana plug into the
positive (V) jack.
3.
Touch the test probe tips to the circuit under test. Be sure
to observe the correct polarity (red lead to positive, black
lead to negative).
4.
Read the voltage in the display. The display will
indicate the proper decimal point and value. If the
polarity is reversed, the display will show (-) minus
before the value.
5.
Press the MODE button until “DC” appears in the
display.
