2)Verify whether the insulation of all test leads, probes and connectors is
intact prior to activating the device.
1. DC Voltage Measurements
1)Connect the red test lead to the "VΩmA" jack and the black lead to the
"COM" jack.
2)Place the RANGE switch in the appropriate VDC position. Set the switch to
the highest range and work your way down if the voltage range is
unknown beforehand.
3)Connect the test leads to the device or circuit to be measured.
4)Activate the device or circuit to be measured. Both the voltage value and
the polarity will be displayed.
2. AC Voltage Measurements
1)Connect the red test lead to the "VΩmA" jack and the black lead to the
"COM" jack.
2)Place the RANGE switch in the appropriate VAC position.
3)Connect the test leads to the device or circuit to be tested.
4)The voltage value will appear on the display.
3. DC Current Measurements
1)Connect the red test lead to the "VΩmA" jack and the black lead to the
"COM" jack. (Connect the red test lead to the "10A"-jack for
measurements between 200mA and 10A).
2)Place the RANGE switch in the appropriate ADC position.
3)Open the circuit to be measured and connect the test leads IN SERIES
with the load of which the current is to be measured.
4)Read the current value on the display.
4. Resistance Measurements
1)Connect the red test lead to the "VΩmA" jack and the black lead to the
"COM" jack.
2)Place the RANGE switch in the appropriate Ω position.
3)If the resistance being measured is connected to a circuit: disconnect the
power and discharge all capacitors prior to measurement.
4)Connect the test leads to the circuit to be measured.
5)Read the resistance value on the display.
5. Diode Measurements
1)Connect the red test lead to the "VΩmA" jack and the black lead to the
"COM" jack.
2)Set the RANGE switch to the
3)Connect the red test lead to the anode and the black test lead to the
cathode of the diode to be measured.
4)The forward voltage drop will be displayed in mV. "1" will be displayed if
the polarity of the diode is reversed.
