4.2 DCV MEASUREMENT
1.Insert the black test lead to “COM” jack, the red one to V/Ωjack.
2.Set the range knob to a proper DCV range, connect the test leads across to the circuit under tested,
the polarity and voltage of the point which red lead connect will display on LCD.
NOTE:
1.If the measured voltage is unsure beforehand, should set the range knob to the highest range, then,
switch to a proper range according to the displayed value.
2.If LCD displays “1”, it means over range, should set the range knob to a higher range.
4.3 ACV MEASUREMENT
1.Insert the black test lead to “COM” jack, the red one to V/Ωjack.
2. Set the range knob to a properACV range, connect the test leads across to the circuit under tested.
NOTE:
1.If the measured voltage is unsure beforehand, should set the range knob to the highest range, then,
switch to a proper range according to the displayed value.
2.If LCD displays “1”, it means over range, should set the range knob to a higher range.
4.4 DCA MEASUREMENT
1.Insert the black test lead to “COM” jack and the red one to“mA” jack（max. 200mA），or insert the
red one to “20A” jack（max. 20A）.
2.Set the range knob to a proper DCA range, connect the test leads across to the circuit under tested,
the current value and polarity of the point which red lead connect will display on LCD.
NOTE:
1.If the measured current is unsure beforehand, should set the range knob to a higher range, then,
switch to a proper range according to the displayed value.
2.If LCD displays “1” , it means overrange, should set the range knob to a higher range.
3. Pay attention to measure 20A.. Continuously measuring large current may heat the circuit, affect the
accuracy, eve damage the meter.
