OPERATION
WARNING: Risk of electrocution. High-voltage circuits, both AC and DC, are very
dangerous and should be measured with great care.
If “1” appears in the display during a measurement, the value exceeds the range you have
selected. Change to a higher range.
WARNING: 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 stabilise and give a proper measurement when
connected to a circuit.
DATA HOLD BUTTON
The Data Hold function allows the Multimeter to “freeze” a measurement for later reference.
1. Press the DATA HOLD button to “freeze” the reading on the Multimeter. The indicators
“HOLD” will appear in the display.
2. Press the DATA HOLD button to return to normal operation.
BACK LIGHT BUTTON
The BACK LIGHT BUTTON is used to turn the back light on only. To extend the battery life, the
back light will turn off automatically within around 3 seconds.
°C/°F BUTTON
The ºC/ºF button is used to select °C or °F function when making temperature measurements.
Set the rotary switch at TEMP position and “°C” is displayed. Push the °C/°F SWITCH, “°F” will be
displayed.
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 Multimeter.
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.
