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 300V position. “HV”sign will appear on the display to remind user of high voltage measurement. Special attention should be paid.

06

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 300V position , a “HV” 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.

07

Diode test

1. Set the function switch at Ω position .(note: the polarity of red lead is positive “+”)

2. Set the range switch at position.

3. Connect the red test lead to the anode of the diode to be tested and the black lead to the cathode of the diode.

4. The approx. forward voltage drop of the diode will be displayed in mv.if the connection is reversed. Only figure

“1”will be shown

Audible continuity test

1. Set the function switch at Ω position.

2. Set the range at position.

3. Connect test leads to two points of the circuit to be tested.

if the resistance is less than 50 Ω. Buzzer will sound.

Battery & Fuse Replacement

If the sign appears on the LCD display .it indicates that the battery should be replaced. Remove the screw on the back cover and open the case .replace the exhausted battery with a new one of the same type.

Fuse rarely need replacement and blow almost always as a result of operator's error. open the case and replace the blown fuse with the ratings specified: F 250 mA/300V.

WARNING

disconnected from the measured circuit before removing the rear cover. Make sure the rear cover is tightly screwed before using the instrument.

Replacing test leads

Replace test leads if leads become damaged or worn.

WARNING

If the test leads need to be replaced, you must use a new one which should meet EN 61010-031 standard, rated CAT III 300V, 0.4A or better.

Warning

Before attempting to open the case .always be sure that test

leads have been disconnected form measurement circuits.

close case and tighten screws completely before using the

meter to avoid electrical shock hazard.
