impedance of measured circuit was smaller than 10MΩ, the measurement error
would be so tiny that could be neglected (0.1% or even smaller).
AC voltage measurement
1. Connect the red test lead to the
“VΩmA”
jack and the black test lead to the
“COM”
jack.
2. Set the range switch to the desired AC voltage range (V~).
3. Connect the test leads across the device or circuit to be measured. Read the
voltage value on the LCD display along with the polarity.

information are both the same as DC voltage
measurement.
DC current measurement
1. Connect the red test lead to the
“VΩmA”
jack or
“10A”
jack, and the black test
lead to the
“COM”
jack.
2. Set the range switch to the desired DC current range (A
).
3. Open the circuit in which the current is to be measured, and connect the test
leads in series with the circuit.
4. Read the current value on the LCD display along with the polarity.
