AC Current (main display) + AC Voltage (secondary display) Measurement

The AC current ranges are: 40A, 100A, 400A and 1000A. The AC Voltage ranges are: 100V, 400V and 750V

To measure AC current + AC voltage, connect the Meter as follows:

1. Dial the Rotary to AAC to select AC Current + AC Voltage range.
2. Press the lever to open the transformer jaw.
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 tested is placed at the center of the transformer jaw, otherwise it will cause deviation. The Meter can only measure one conductor at a time, to measure more than one conductor at a time will cause deviation.
4. The double display shows the AC current True RMS value and AC voltage True RMS value.
5. Press MAXMIN, the LCD displays MAX, it starts recording the maximum AC current True RMS value.
6. Press MAXMIN, the LCD displays MIN, it starts recording the minimum AC current True RMS value.
   Press MAXMIN, again to show the present AC current True RMS value.
7. The display shows 0L when the current of the tested conductor is higher than 1000A rms.

Note: When the 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.

AC Voltage (main display) + Frequency (secondary display) Measurement

The AC Voltage ranges are: 100V, 400V and 750V. The frequency range is: 50Hz~60Hz.

To measure AC voltage + frequency, connect the Meter as follows:

1. Insert the red test lead into the L1, L2, L3 input terminal, and black test lead to the COM input terminal.
2. Dial the Rotary to VAC to select Voltage + Frequency range.
3. Connect the red test leads (L1, L2, L3 input terminal) to the corresponding three phases loaded live wire. Black test lead (COM input terminal) to the corresponding three phases loaded neutral wire.
4. Press SEL to select phase location, the display shows the corresponding phase symbol. L1 means the first phase Ø1, L2 means the second phase Ø2, L3 means the third phase Ø3.
5. The display shows the corresponding True RMS voltage value and frequency value of each phase.
6. Press MAXMIN, the LCD displays MAX, it starts recording the maximum AC voltage True RMS value.
7. Press MAXMIN the LCD displays MIN, it starts recording the minimum AC voltage True RMS value.
   Press MAXMIN again to show the current AC voltage True RMS value.
8. The display shows 0L when the input voltage is higher than 750V rms.

Note: When the measurement has been completed, disconnect the connection between the testing leads and the circuit under test and remove testing leads from the input terminals.

Active Energy (main display) + Time (secondary display) Measurement

Warning. To avoid damages to the Meter or harms to you, do you measure higher than AC voltage 750V rms and AC current 1000A rms.

To test for Active Energy (main display) + Time (secondary display), connect the Meter as follows:

1. Dial Rotary to ENERGY range.
2. Press the lever to open the transformer jaw, and clamp them to the corresponding phase of tested conductor.
3. Insert red test leads to L1 input terminal and connecting it.
4. Insert black test leads to COM input terminal and connect it.
5. MAXMIN are not valid when measuring active energy.

Note

• When there is no input signal, it cannot carry out active energy measurement.
• When testing has been completed, disconnect the connection between the testing leads and the circuit under test and remove testing leads from the input terminals.

True RMS Measurement and Average Value Measurement

The True RMS measurement method can measure accurately the effective value of non-sine wave input signal.

Average value measurement method can measure the mean value of one sine wave input signal, and then displays it as RMS value When the input waveform has distortion, measuring tolerance will be included. The total tolerance depends on the total distortion. Below table shows the waveform coefficient and the relationship and the requested changing factor of sine wave, square wave, pulse rectangle wave, saw tooth triangle wave, RMS value and average value. The clamp Meter software designing base on the following formula:
