1.Home check: 80-300V~100A's.

2.AC200-450V~0.00-100.0A
Note: if you want to simultaneously measure ABC/ three-phase voltage, current must be purchased3 meters, three-phase 4 wire, check 80-300V/, three-phase 3 wire, tick 200-450V

D69-2049 type digital display multi-function table

 

Patent counterfeiting products! Instrument patent number:201630467779.8


Instructions and parameters are as follows

The D69-2049 digital display multi-function meter displays the measured AC voltage, AC current and active power at the same time on an instrument,Electricity quantity.The instrument display section is adoptedColor LCD HDMonitor.

1.Measuring accuracy: 1%± 2 words

2. measuring range:AC voltage: AC80.0-300.0V or AC200.0-450.0V,True RMS measurement,CustomerSelect an appropriate range according to requirements when placing an order.

AC current: AC0-99.99A, current display resolution of 0.01A, more than 100A display 100.0A

Active power: display range 0-10000W display 0-9999.9W, 10000W above, show 10000-22000W

Power: measuring range is 0-9999999kwh

0-9999.999kwh display resolution of 0.001kwh

10000.00-99999.99kwh display resolution of 0.01kwh

The 100000.0-999999.9kwh display is resolved as 0.1kwh,

The rest is 1kwh

3. measuring speed: 2 times per second

4. size: 79*43*48mm

LCD screen size: 52*26mm

Font height: 6mm

5. installation size: 76*39mm

6. storage / memory function: when the instrument is in power failure, the cumulative value of the meter will be stored.

(7.100A transformer hole diameter 15.5mm) can meet GB 21-25 square (mm) standard copper wire through

Use and wiring methods

1. according to the wiring diagram wiring drawings, with the two end of the instrument current transformer (green wire), blue terminal received instrument, the middle hole wire will measure the circuit through the current transformer.

2. connect the voltage measuring lead to the green terminal of the instrument, then measure the voltage as above and start reading the measurement result.

3. after the power supply, the meter shows the measured value.

4. press the reset button on the front panel of the instrument for 5 seconds, and the total value of the instrument's power will be cleared.

5.Extreme working condition:

 

Operating temperature:-10~+50C
Operating humidity:10~80%(without gel)
Working pressure:80~106kPa
Sun exposure: no direct radiation

Matters needing attention

1. voltage input (green) terminals and current transformers, the two input terminals (blue) wiring terminals can not be connected wrong, otherwise the instrument will be damaged!!!

2. this meter is only suitable for pure AC 50-60HZ power supply. It can not be used for square wave, inverter output and corrected positive wave circuit. Otherwise, the instrument will be damaged!!!

3. installed instrument process, remember not to squeeze the instrument LCD screen, otherwise it will appear garbled / broken code situation!!!

4.Many buyers respond: "what's wrong with my test data? Voltage = current = power. The actual test power is less than the voltage * current."
Answer: This shows that many buyers of electrician basic knowledge is very lacking. This simple popularity below, hope don't say the table there is a problem: power is divided into three types: active power (P / W) and reactive power (Q / Var) and apparent power (S / VA). Here only the active power, other buyers please Baidu. The calculation formula of active power: P=U*I*cosφ cosφ, on behalf of the power factor, the pure resistance load (such as incandescent lamp, heater, etc.) the power factor is close to 1, inductive and capacitive load power factor between 0-1; so when testing the pure resistance load, P is substantially equal to or close to the U*I test; inductive or capacitive load (such as a refrigerator, washing machine, TV, computer etc.) when P < U*I, as for how much to relate to the power factor, power factor of each appliance.
