Main technical indicators
Measurement accuracy: 1% ± 2 words
Measurement range: AC voltage: AC40.0-300.0V or AC200.0-450.0V, true RMS measurement.
AC current: AC0-99.99A, current display resolution is 0.01A, and 100.0A is displayed when it exceeds 100A
Active power: 40-300V display range 0-30000W, 200-450V display range 0-45000W, display resolution between 0-9999.9W is 0.1W, [the rest is 1W]
Electric energy: the measuring range is 0-99999kwh, 0-999.99kwh, the minimum display resolution is 0.01kwh, 10000.0-9999.9kwh, the minimum display resolution is 0.1kwh, 10000.0-99999kwh, the minimum resolution is 1kwh
Power frequency: 45.0Hz-65.0Hz
Power factor: 0.00-1.00PF
Measurement speed: 2 times per second
Boundary dimension: 70 * 40 * 39mm
Installation dimension: 68 * 38mm
Memory function: When the instrument is powered off during use, the accumulated value of the instrument's power will be stored automatically (the previous electric energy data will be saved).
Operating instructions
-
Connect the secondary end (green lead) of the current transformer attached to the instrument to the blue terminal of the instrument, and pass the wire of the measuring circuit through the middle round hole of the current transformer.
-
Connect the voltage measuring lead to the green terminal of the instrument, and then measure the voltage as above, and start to read the measurement results.
-
After the power is turned on, the instrument displays the measured value.
-
Press and hold the reset button on the front panel of the instrument for 5 seconds, and the accumulated value of the instrument will be reset.
-
100A transformer hole diameter 15mm can meet the national standard 21-25 square mm standard copper wire through
-
Extreme working conditions:
Working temperature: - 10~+50 ℃
Working humidity: 10~80% (no condensation)
Working pressure: 80~106kPa
Sunlight exposure: no direct exposure
Matters needing attention
-
The wiring of voltage input (green) terminal and current transformer secondary input terminal (blue) terminal cannot be connected incorrectly, otherwise the instrument will be damaged!
-
The 200-450V specification of this instrument cannot be used for measurement on square wave, inverter output and corrected positive and negative wave circuit, otherwise the instrument will be damaged! AC40-300V unlimited
-
During the installation of the instrument, remember not to squeeze the LCD screen of the instrument, otherwise there will be garbled/broken code!
-
If more than one instrument is purchased for use, the mutual inductor cannot be used interchangeably! [Because the instrument and transformer are calibrated in a pair] to avoid affecting the measurement accuracy!
-
Please check 40-300V 100A to measure 110V 220V grid voltage and check 200-450V to measure 380V voltage! If 200-450V is checked to measure 220V voltage, it is not allowed to measure when the voltage is lower than 220V! Remember.
