Measurement Operation

DC Voltage Measurement

DC Voltage Ranges: 200mV, 2000mV, 20V, 200V, 500V
Input Impedance: 10M ohms

1. Plug the red test lead into the V ohm mA terminal, then plug the black test lead into the COM terminal.
2. Set the rotary switch to the appropriate measurement in V range.
3. Connect the test leads to the object of measurement. Hold them in place until the results on the display stabilize.
4. When measurement is completed, disconnect the test leads from the object of measurement.

NOTE

• If the value of voltage is unknown, use the maximum measurement position (500V) and reduce the range until proper readings are obtained.
• The LCD will display “OL” if there in an overload within the selected range. Select a higher range to obtain a correct reading.
• If the circuit impedance is less than or equal to 10k ohm, the error is negligible (0.1% or less).

AC Voltage Measurement
(See Figure 2)
AC Voltage Ranges: 200V, 500V
Input Impedance: 5M ohms

1. Plug the red test lead into the V ohm mA terminal, then plug the black test lead into the COM terminal.
2. Set the rotary switch to the appropriate measurement in V~ range.
3. Connect the test leads to the object of measurement. Hold them in place until the results on the display stabilize. The displayed measured value is the value of sine wave (mean value response).
4. When measurement is completed, disconnect the test leads from the object of measurement.

NOTE

• If the value of voltage is unknown, use the maximum measurement position (500V) and reduce the range until proper readings are obtained.
• The LCD will display “OL” if there in an overload within the selected range. Select a higher range to obtain a correct reading.
• If the circuit impedance is less than or equal to 10k ohm, the error is negligible (0.1% or less).

DC Current Measurement
WARNING
Never attempt an in-circuit current measurement where the voltage between the terminals and ground is greater than 60V. If the fuse burns out during
measurement, this may cause harm to the user and/or damage to the device. Use proper terminals, functions, and range for measurement.
When the testing leads are connected to the current terminals, do not parallel them across any circuit.

DC Current Ranges: 2000μA, 20mA, 200mA, 10A

1. Turn off the power to the circuit and discharge all high voltage capacitors.
2. Plug the red test lead into the V ohm mA or 10A terminal, then plug the black test lead into the COM terminal.
3. Set the rotary switch to the appropriate measurement in A range.
4. Break the current path to be tested.
5. Connect the red test lead to the most positive side of the break and the black test lead to the most negative side of the break.
6. Turn on the circuit power.
7. When measurement is completed, disconnect the test leads from the object of measurement.

NOTE
If the value of voltage is unknown, use the maximum measurement position (10A) and reduce the range until proper readings are obtained.

Resistance Measurement

Resistance Ranges: 200 ohm, 2000 ohm , 20k ohm, 200k ohm, 20M ohm, 200M ohm

1. Plug the red test lead into the V ohm mA terminal, then plug the black test lead into the COM terminal.
2. Set the rotary switch to the appropriate measurement in ohm range.
3. Connect the test leads to the object of measurement, the measured value will appear on the display.
4. When measurement is completed, disconnect the test leads from the object of measurement.

NOTE

• The test leads can add 0.1 ohm to 0.3 ohm of error to the resistance measurement. To obtain precise readings in low resistance measurement (200 ohm), short-circuit the input terminals beforehand and record the reading obtained (reading X). This is the additional resistance from the test lead. Then use the equation: Measured resistance value (Y) – (X) = resistance result
• For high-resistance measurements (>1M ohm), it may take a few seconds for the reading result to stabilize.

Diode Measurement

WARNING
To avoid damage to the meter and/or the object of measurement, disconnect the circuit power and discharge all the high-voltage capacitors before diodes.
Test to check diodes, transistors, and other semiconductor devices. The diode test sends a current through the semiconductor junction, then measures the voltage drop across the junction. A good silicon junction drops between 0.5V and 0.8V.

1. Plug the red test lead into the V ohm mA terminal, then plug the black test lead into the COM terminal.
2. Set the rotary switch to the setting.
3. For forward voltage drop readings on any semiconductor component, place the red test lead on the component’s anode and place the black test lead on the component’s cathode. Hold them in place until the results on the display stabilize.
4. When measurement is completed, disconnect the test leads from the object of measurement.

NOTE

• In a circuit, a good diode should still produce a forward voltage drop reading of 0.5V to 0.8V; however, the reverse voltage drop reading can vary depending on the resistance of other pathways between the probe tips.
• The LCD will display “OL” if the open circuit is incorrectly connected.
• The unit of diode is volt (V), displaying the positive connection voltage-drop value.

Continuity Measurement

1. Plug the red test lead into the V ohm mA terminal, then plug the black test lead into the COM terminal.
2. Set the rotary switch to the setting.
3. Connect the test leads across with the object of measurement.
4. The buzzer will sound if the resistance of the circuit is under 70 ohms.

NOTE
The LCD will display “OL” if the circuit is open

Square Wave Output

WARNING
To avoid damage to the meter and/or the object of measurement, do not allow output terminals (red test lead) to surpass 10V.

1. Plug the red test lead into the V ohm mA terminal, then plug the black test lead into the COM terminal.
2. Set the rotary switch to the OUT setting.
3. Connect the test leads across with the object of measurement. Hold them in place until the results on the display stabilize.
4. When measurement is completed, disconnect the test leads from the object of measurement.

NOTE

• The frequency is approximately 50Hz.
• When loaded to 1M ohm, the output scope will be higher than 3Vpp.
