D85-2058 digital display multi-function meter is to display the measured AC voltage, AC current, active power, power factor, frequency, and six electrical on the same screen at the same time. The instrument display part adopts color high-definition liquid crystal display.
Main Specifications
Measurement accuracy: 1% ± 2 digits
Measuring range: AC voltage: AC40.0-300.0V or AC200.0-450.0V, true RMS measurement.
AC current: AC0-99.99A, the current display resolution is 0.01A, when it exceeds 100A, it will display 100.0A
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 measurement range is 0-99999kwh, the minimum display resolution of 0-999.99kwh is 0.01kwh, the minimum display resolution of 10000.0-9999.9kwh is 0.1kwh, and the minimum display resolution of 10000.0-99999kwh is 1kwh
Power frequency: 45.0Hz-65.0Hz
Power factor: 0.00-1.00PF
Measuring speed: 2 times per second
Dimensions: 70*40*39mm
Installation size: 68*38mm
Memory function: When the meter is powered off during use, the accumulated power value of the meter will be stored by itself (the previous power data is saved).
Instructions for use
Connect the secondary terminal (green lead wire) of the current transformer attached to the meter to the blue terminal of the meter, and pass the wire of the measuring circuit through the middle hole of the current transformer.
Connect the voltage measurement lead to the green terminal of the instrument, then measure the voltage as above, and start to read the measurement results.
After the power is turned on, the meter will display the measured value.
Press and hold the reset button on the front panel of the meter for 5 seconds, and the accumulated power value of the meter will be reset to zero.
100A transformer hole diameter 15mm can meet the national standard 21-25mm2 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
Precautions
The wiring of the voltage input (green) terminal and the current transformer secondary input terminal (blue) must not be connected incorrectly, otherwise the instrument will be damaged!
The 200-450V specification of this meter cannot be used for square wave, inverter output and corrected sine wave circuits, otherwise the meter will be damaged! AC40-300V unlimited
Remember not to squeeze the LCD screen of the instrument during the installation of the instrument, otherwise there will be garbled/broken es!
If multiple meters are purchased for use, the transformers cannot be used interchangeably! [Because the instrument and the transformer are a pair of calibration] so as not to affect the measurement accuracy!
Please check 40-300V 100A to measure 110V 220V grid voltage and 200-450V to measure 380V voltage! If you check 200-450V to measure 220V voltage, the measurement is not allowed when the voltage is lower than 220V! Remember.
