Measurement Operation

To avoid harms to you or damages to the Meter from eletric shock, do not attempt to measure voltages higher than 600V AC/DC, although readings may be obtained.
The AC Voltage ranges are: 2.000V, 20.00V, 200.0V and 600V

To measure AC voltage, connect the Meter as follows:

1. Insert the red test lead into the terminal and the black test lead into the COM terminal.
2. Set the rotary switch to
3. Connect the test leads across with the object being measured. The measured value shows on the display.

Note

• In each range, the Meter has an input impedance of 10M. This loading effect can cause measurement errors in high impedance circuits. If the circuit impedance is less than or equal to 10kQ, the error is negligible (0.1 or less).
• When AC voltage measurement has been completed, disconnect the connection between the testing leads and the circuit under test and remove testing leads from the input terminals.

Measuring Resistance

(See Figure 5)

To avoid harms to you, donot attempt to input voltages higher than 60V DC or 30V rms AC.
To avoid damages to the Meter or to the devices under test, disconnect circuit power and discharge all the high-voltage capacitors before measuring resistance.

The resistance ranges are:
200.09, 2.000kQ, 20.00k2,200kQ,2.000MQ and 20.00MQ.
To measure resistance, connect the Meter as follows:

1. Insert the red test lead into the terminal and the black test lead into the COM terminal.
2. Set the rotary switch to .
3. Connect the test leads across with the object being measured.
   The measured value shows on the display.

To avoid damages to the Meter or to the devices under test, disconnect circuit power and discharge all the high-voltage capacitors before testing diodes.
Use the diode test to check diodes, transistors, and other semiconductor devices. The diode test sends a current through the semicondutor junction, then measure the voltage drop across the junction. A good silicon junction drops between 0.5V and 0.8V.

To test the diode out of a circuit, connect the Meter as follows:

Note

• In a circuit, a good diode should still produce a forward voltage drop reading of 0.5V to 0.8; however, the reverse voltage drop reading can vary depending on the resistance of other pathways between the probe tips.
• Connect the test leads to the proper terminals as said above to avoid error display.
• The LCD will display OL indicating either open circuit or wrong polarity connection.
• The unit of diode is volt (V), displaying the forward voltage drop readings.
• Measuring the tested object that is already removed from the in-line circuit can help to obtain a more accurate reading.
• When diode testing has been completed, disconnect the connection between the testing leads and the circuit under test and remove testing leads from the input terminals.

Testing for Continuty

(See Figure 7)

To avoid damages to the Meter or to the devices under test, disconnect circuit
power and discharge all the high-voltage capacitors before measuring continuity.

To test for continuity, connect the Meter as follows:

1. Insert the red test lead into the «VO terminal and the black test lead into the COM terminal.
2. Set the rotary switch to =)-+ and press SELECT button to select +) measurement mode.
3. The buzzer sounds if the resistance of a circuit under test is less than 50Q.
4. The buzzer may or may not sounds if the resistance of a circuit under test is between 502to 1202.
5. The buzzer does not sound if the resistance of a circuit under test is higher than 1200.

Note

• The buzzer beeps 5 times continuously on around 1 minute before entering the sleep mode. When it is just before entering the sleep mode, it will have one long beep to warn you.
• The LCD displays OL indicating the circuit being tested is open.
• When continuity testing has been completed, disconnect the connection between the testing leads and the circuit under test and remove testing leads from the input terminals.

To avoid electric shock, never measure current while the test leads are inserted into the input terminals and disconnect test leads and tested circuit connection.
Never attempt an in-circuit current measuremnet where the open-circuit voltage between the circuit and the ground is greater than 600V
Use proper function and range for the measurement.

The measuremnet ranges of current are: 2.000A, 20.00A, 200.0A and 400A.

To measure current, do the following:

1. Set the rotary switch to 2/20A~or 200/400 A~
2. Press the trigger to open the transformer jaws.
3. Center the conductor within the transformer jaw. then release the Meter slowly until the transformer jaw is completely closed, Make sure the conductor to be to be tested is placed at the center of the transformer jaw, otherwise it will casue deviation.
4. The measured value shows on the display, it is a effective value of sine wave (mean value response)

Note:

• To obtain accurate reading, measure only one conductor at each time.
• When current measurement has been completed, disconnect the connection between the conductor under test and the jaw, and remove the conductor away from the transformer jaw of the Meter.

Sleep Mode

To preserve battery life, the Meter automatically turns off if you do not turn the rotary switch or press any button for around 15 minutes. The Meter can be activated by turning the rotary switch or pressing any button with the following conditions:
The Hold function will be cancelled if the Meter is activated by pressing the HOLD button. To disable the Sleep Mode function, press and hold HOLD button while turning on the Meter.
