Operating instruction
DC Voltage measurement
1. Set the function switch at V position
2. Set the range switch at desired position. If the magnitude
of voltage to be measured is unknown beforehand .
set the range switch at the highest position and then
reduce until satisfactory reading is obtained.
3. Connect test leads across the source or load being
measured. The polarity of red lead connection will be
indicated at the same time as the voltage value.
4. When the range switch is set at position. “HV”sign 600V
will appear on the display to remind user of high voltage
measurement. Special attention should be paid.

AC Voltage measurement
1. Set the function switch at V~ position
2. Set the range switch at desired position .measurement
reading can be obtained at 2V and 20V positions, but
the accuracy is not guaranteed.
3. Connect test leads across the source or load being
measured and read the voltage value on the LCD display.
4. When the range switch is set at position , a “HV” 600V
sign will appear on the display to remind user of high
voltage measurement.
DC Current measurement
1. Set the function switch at A position.
2. Set the range switch at 200mA position .measurement
reading can be obtained at other positions. But the
decimal point will be at the incorrect place.
3. Open the circuit in which the current is to be measured.
And connect test leads in series with the circuit.
4. Read current value on the LCD display along with the
polarity of red lead connection.
Resistance measurement
1. Set the function switch at Ω position .(note: the polarity
of red lead is positive “+”)
2. Set the range switch at desired position
3. Connect test leads across the resistor to be measured
and read LCD display.
4. If the resistor was being measured is connected to a
circuit .turn off power and discharges all capacitors
before applying test leads.
