AC/DC VOLTAGE MEASUREMENT
On some low AC and DC voltage ranges - when test leads are not connected to a
device - the display on the screen may show a random, changing reading. This is
normal and caused by high-input sensitivity of the multimeter. When connected
to a circuit, the multimeter will display a stabilised, accurate measurement.
1) Set the function switch to the VAC or VDC position.
2) Insert the black test lead banana plug into the negative COM jack.
3) Insert the red test lead banana plug into the positive VΩCAP jack.
4) Use the Mode button to select AC or DC voltage.
5) Connect the test leads in parallel to the circuit under test.
6) Read the voltage in the display.
DC CURRENT MEASUREMENT
Do not measure 20A currents for longer than 30 seconds. Exceeding 30 seconds
may cause damage to the meter and/or test leads.
1) Insert the black test lead banana plug into the negative COM jack.
• For current measurements up to 4000μA DC, set the function switch to the μA
position and insert the red test lead banana plug into the μA jack.
• For current measurements up to 400mA DC, set the function switch to the mA
position and insert the red test lead banana plug into the mA jack.
• For current measurements up to 10A DC, set the function switch to the 10A
position and insert the red test lead banana plug into the 10A jack.
2) Press the MODE button to show “DC” on the screen.
3) Remove power from the circuit under test, then open up the circuit at the point
where you wish to measure current.
4) Touch the black test probe tip to the negative side of the circuit.
5) Touch the red test probe tip to the positive side of the circuit.
6) Apply power to the circuit.
7) Read the current displayed on the screen.
AC CURRENT MEASUREMENT
Do not measure 20A currents for longer than 30 seconds. Exceeding 30 seconds
may cause damage to the meter and/or test leads.
1) Insert the black test lead banana plug into the negative COM jack.
• For current measurements up to 10A, set the function switch to the 10A
position and insert the red test lead banana plug into the 10A jack.
