Specifications:

• Accuracy: 1% ± 2 words

• Speed: 2 times per second

• Size: 54×80×64mm

• Installation: Din-Rail

• AC current: AC 0 -100.0A, the current resolution is 0.01A.

• Frequency: 45.0Hz – 65.0Hz

• Power factor: 0.00-1.00PF

• AC voltage: AC 40.0-300.0V or AC 250.0-450.0V

• Use:

• 1. Connect the measuring voltage to terminals 1 and 2.

• 2. The connection between the instrument and the internal current transformer is shown in Figure 1. Pass the wire through the hole on the instrument, and choose any direction.

• 3. The connection between the instrument and the external current transformer is shown in Figure 2. Pass the wires through the holes on the instrument and connect the two wires of the secondary transformer to terminals 3 and 4.

• 4. When turned on, the meter displays the measurement parameters.

• 5. When powered on, press and hold the SAM CK button for 5 seconds. After releasing the button, the power will return to zero and start accumulating. And when the power is turned off, the meter can save the electric energy value and continue to accumulate data when the power is next turned on.

Note: The meter can only be used to measure 45-65Hz AC.
