3. FUNCTION DESCRIPTION
3.1 General Functions
3.1.1 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.
2. A second short press returns the meter to normal mode.
3.1.2 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 200.0mV, 2.000V,
20.00V, 200.0V and 1000V；AC voltage ranges are 2.000V,
20.00V, 200.0V and 7500V.

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
discharge all high-voltage capacitors before
measuring resistance.
Resistance is an opposition to current flow.
The unit of resistance is the ohm (Ω).
The Meter's resistance ranges are 200.0Ω, 2.000kΩ,
20.00kΩ, 200.0kΩ, 2.000MΩ, 20.00MΩ and 200.0MΩ.
To measure resistance:
1. Set the rotary switch to proper range.
2. Connect the black and red test leads to the COM and
Ω terminals respectively.
3. Connect the test leads to the circuit being measured
and read the displayed value.
