Measuring DC or AC Current
Warning
1. Set the range switch to desired "
2. Select ac current measurement ( "
3. Select autorange mode or manual range mode with the "RANGE" button.
4. Connect the black test lead to the "COM" terminal and the red test lead to the "A°C°F°" terminal.
5. Turn off power to the circuit which you will test. Then discharge all capacitors.
6. Break the circuit path to be tested, and connect the test leads in series with the circuit.
7. Turn on power to the circuit, then read the display. For dc current measurements, the polarity of the red test lead connection will be
indicated as well.
Note: If you don't knowthe magnitude of the current to be measured beforehand, select the highest range and then reduce it range
by range until satisfactory resolution is obtained.

Measuring Resistance

1. Connect the black test lead to the "COM" terminal and the red test lead to the "
2. Set the range switch to
appear on the display.
4. Read the reading on the display.
Note :
, the meter may take a fewseconds to stabilize reading. This is normal for high resistance measurements.
2. When the input is not connected, i.e. at open circuit, "OL" will be displayed as overrange indication.
3. Before measurement, disconnect all power to the circuit to be tested and discharge all capacitors thoroughly.

Continuity Test

1. Connect the black test lead to the "COM" terminal and the red test lead to the "
2. Set the range switch to
3. Connect the test leads across the circuit to be tested.
4. If the resistance is less than about 30 , the built-in buzzer will sound.
Note: Before test, disconnect all power to the circuit to be tested and discharge all capacitors thoroughly.

Measuring Frequency

1. Connect the black test lead to the "COM" terminal and the red test lead to the "
2. Set the range switch to Hz position.
3. Connect the test leads across the source or load to be tested.
4. Read the reading.
Note* The voltage of the input signal should be between 500mV rms and 20V rms. If the voltage exceeds 20V rms, the accuracy of
reading may be out of the specified accuracy range.
