4.1. AC/DC VOLTAGE MEASUREMENT
WARNING: Observe all safety precautions when working on live voltages.
CAUTION: Do not measure voltages if a motor on the circuit is being switched ON or OFF. Large voltage
surges may occur that can damage the meter.
„ Set the rotatory function switch to the VAC/DC position.
„ To select AC or DC voltage, press the MODE button until the
LCD display.
„ Insert the black test lead banana plug into the negative COM terminal; Insert the red test lead banana
plug into the + terminal.
„ Touch the black test probe tip to the negative side of the circuit; Touch the red test probe tip to the
positive side of the circuit.
„ Read the voltage on the LCD display.
„ Press the MODE button to indicate Hz.
„ Read the frequency in the display.
4.2. FREQUENCY MEASUREMENT
WARNING: Observe all safety precautions when working on live voltages.
„ Set the rotatory function switch to the Hz position.
„ Insert the black test lead banana plug into the negative COM terminal; Insert the red test lead banana
plug into the + terminal.
„ Touch the test probe tips to the circuit under test.
„ Read the frequency on the display.
4.3. AC/DC CURRENT MEASUREMENT
WARNING: Observe all safety precautions when working on live circuits. Measurements in the 10A
range should be limited to 30 seconds maximum every 15 minutes.
„ Insert the black test lead banana plug into the COM terminal.
„ For current measurements up to 10A AC/DC, set the rotary function switch to the 10A position and
Insert the red test lead into the 10A terminal.
„ For current measurements up to 400mA AC/DC, set the rotary function switch to the mA position
and Insert the red test lead into the + terminal.
„ For current measurements up to 4000µA AC/DC, set the rotary function switch to the µA position
and Insert the red test lead into the + terminal.
„ Press the MODE button to select AC or DC current, the
LCD display.
„ Remove power from the circuit under test, then open up the circuit at the point where you wish to
measure current.
„ Touch the black test probe tip to the neutral side of the circuit; Touch the red test probe tip to the
"hot" side of the circuit.
„ Apply power to the circuit, Read the current on the LCD display.
4.4. RESISTANCE MEASUREMENT
WARNING: Never test resistance on a live circuit.
„ Set the rotary function switch to the
„ Press the MODE button until the Ω symbol appears on the LCD display.
„ Insert the black test lead banana plug into the negative COM terminal; Insert the red test lead banana
plug into the + terminal.
