3.1.2 DATA HOLD mode
Data Hold mode makes the meter stop updating the
display. Data Hold function can be cancelled by
changing the measurement mode, or push HOLD
key again.
To enter and exit the Data Hold mode:
1. Press HOLD key. Fixes the display on the current
value,
is displayed.
H
2. A second short press returns the meter to normal
mode.
3.1.3 Battery Saver
Turn on the meter. And then The Meter will be turned
off automatic after approx. 30 minutes.
3.2 Measurement Functions
3.2.1 AC and DC Voltage measurement
To avoid electrical shock and/or damage to the
instrument, do not attempt to take any voltage
measurement that might exceeds 1000Vdc or
750Vac rms.
To avoid electrical shock and/or damage to the
instrument, do not apply more than 1000Vdc or
750Vac rms between the common terminal and
the earth ground.

Voltage is the difference in electrical potential between
two points. The polarity of ac (alternating current)
voltage varies over time; the polarity of dc (direct
current) voltage is constant.
The Meter's DC voltage ranges are 200.00mV, 2.0000V,
20.000V, 200.00V and 1000.0V；AC voltage ranges
are 2.0000V, 20.000V, 200.00V and 750.0V.
To measure ac or dc voltage:
1. Set rotary switch to the proper range.
2. Connect the black and red test leads to the COM
and V terminals respectively.
3. Connect the test leads to the circuit being measured
4. Read the displayed value. The polarity of red test
lead connection will be indicated when making a
DCV measurement.
Note:
Unstable display may occur especially at DC200mV
and AC2V ranges, even though you do not put test
leads into input terminals, in this case, if an erroneous
reading is suspected, short the V terminal and the
COM terminal, and make sure the zero display.
3.2.2 Resistance measurement
To avoid electrical shock and/or damage to the
instrument, disconnect circuit power and
discharge all high-voltage capacitors before
measuring resistance.
