D85-2058 Single-Phase Household Digital LCD AC Panel Meter Intelligent Voltage Current Frequency Power Monitor

Attention

1. The wiring of the voltage input (green) terminal and current transformer secondary input (blue) terminal cannot be connected wrongly, otherwise the meter will be damaged!
2. 200-450v specifications of this instrument can not be used for square wave, inverter output, and corrected sine wave circuit measurement, otherwise, the instrument will be damaged! 40-300v unrestricted use.
3. Remember not to squeeze the LCD screen during the installation of the meter, otherwise, the code will be messed up/broken!
4. If you buy more than one instrument to use, the transformer can not be used interchangeably! Because the instrument and the transformer is a pair of calibration] so as not to affect the measurement accuracy!

3. Measuring speed: 2 times per second

4. External Dimension: 70*40*39mm

5. Installation size: 68*38mm

6. Memory function: when the meter is used in the process of power outage the meter's power accumulated value will be self-storage (before the power data preservation).

Operating instructions for use

1. Connect the wiring according to the attached wiring diagram, connect the secondary end of the current transformer (green lead) with the instrument to the blue terminal of the instrument, and pass the measuring circuit lead through the middle hole of the current transformer.

2. Connect the voltage measurement lead to the green terminal of the instrument, then measure the voltage as above and start reading the measurement results.

3. Turn on the power and the instrument displays the measured value.

4. Press and hold the zero button on the front panel of the instrument for 5 seconds, the accumulated value of the power of the instrument will be cleared to zero.

5. 100A transformer hole diameter of 15mm can be through the national standard 21-25 square mm standard copper wire

6. Limit working conditions:
operating temperature: -10 ~ +50 ° C
Working humidity: 10 ~ 80% (no condensation) Working air pressure: 80 ~ 106kPa
