Measuring Current
Warning
To avoid personal injury or damage to the meter :
• Never attempt to perform an in-circuit current measurement when the open circuit potential to earth is more than 600V.
• Use the proper terminals, switch position, and range for your measurement.
• Don't use the meter to measure currents above 400mA.
• Never place the probes in parallel with a circuit or component when the test leads are plugged into the current terminals.
• Check the meter's fuse before measuring.
1. Set the range switch to desired "
If you select manual range mode and don't know the magnitude of the current to be measured beforehand, select the highest range and
then reduce it range by range until satisfactory resolution is obtained.
2. Connect the black test lead to the "COM" jack and the red test lead to the "
3. Turn off power to the circuit which you will measured. Dicharge all capacitors.
4. Break the circuit path to be measured, connect the test leads in series with the circuit.
5. 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.
Measuring Resistance
1. Connect the black test lead to the "COM" jack and the red test lead to the "
2. Set the range switch to Ω range.
3. Connect test leads across the load to be measured.
4. Read the reading on the display.
Note :
1. For resistance above 1MΩ, the meter may take a few seconds to stabilize reading. This is normal for high resistance measuring.
2. When the input is not connected, i.e. at open circuit, "OL" will be displayed as overrange condition.
3. Before measuring in-circuit resistance, make sure that the circuit under test has all power removed and all capacitors are fully
discharged.
Continuity Test
1. Connect the black test lead to the "COM" jack and the red test lead to the "
2. Set the range switch to
3. Connect the test leads to the circuit to be measured.
4. If the circuit resistance is less than about 30Ω, the built-in buzzer will sound.
Note: Before performing in-circuit continuity test, make sure that the circuit under test has all power removed and all capacitors are
fully discharged.
Measuring Frequency
1. Connect the black test lead to the "COM" jack 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 measured.
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.
