DCUU PM9911 single phase power meter 5kHz - All it secrets

[Kiriakos GR]

DCUU PM9911 this is a modern in design single phase power meter.
It has identical rich measuring features with PM9913 2A (low power model with precision resistor as a shunt).

PM9911 this has current range of 5mA up to 20A.
Current sensor type, by 99% this is PCB mounted precision current transformer.

PM9911 this is designed to handle small, medium and high loads.
Voltage range 5V up to 600V True RMS, it can operate at 230V and 380V applications.
Best accuracy 0.5 Class at 45-65Hz, and it can measure up to 400Hz (With loosen Class 0.8 )

Power (watts) 1.2 or higher at 230V and or Power (watts) 0.6 or higher at 120V

DCUU brand translates to:  Zhongshan Zhongxiang Instrument Co., Ltd, (This is a small factory at China mainland).
The company delivers one year warranty.

Its DCUU instrument, comes with:
1) Quality control inspection card
2) Calibration Certificate     
3) User manual
4) Power cord   
   
Note 1: This topic serves as quick information.
Note 2: Currently are unknown actual voltage and current ranges of it.
Note 3: Direct communication with the brand this is currently an issue, they are not prepared so to talk directly to westerns.
Note 4: PM9911 not compatible for Stand by Power / EU  COC Tier 2

F LED window functionality explained.

MAX V / measurement of peak voltage / Continuously maintain the maximum value
MAX I / measurement of the peak current / Continuously maintain the maximum value
VA     / Apparent power /  Continuously refreshed
Var   / Reactive power  / Continuously refreshed


Other supported functions:
Display Hold  / Lock the current measurement value and use it to display the value.
Programmable alarm,  Low / High limits (with beeper alarm, and visual alarm due flashing digits).
Beeper alarm with mute setting.

LED Indicators:
OK Alarm status indicator
When qualified, it flashes continuously

UPPER Alarm status indicator
When qualified, it flashes continuously if it exceeds the upper limit

LOWER Alarm status indicator
When unqualified, it flashes continuously if it exceeds the lower limit

DCUU, they need to print this topic and make it, their own user manual.   

Excellent work mate !
