DCUU PM9913 this is single phase power meter 5kHz Bandwidth, and the most modern and advanced in electronic design instrument at it class.
DCUU PM9913, PM9911, PM9912, background and history:
DCUU brand translates to: Zhongshan Zhongxiang Instrument Co., Ltd, (This is a small factory at China mainland).
This brand, its actually a team of very young people, and Mr. Deng Changgui this is the general manager.
DCUU this is focused at 100% at the domestic market of China, their primary business focus, quality control testing systems for LED lamps.
In their own portfolio, is the development of digital power meter, mainly for production line testing.
PM991x series this were introduced at the beginning of 2017.
This has six active windows, and update rate of 5 measurements per second.
DCUU PM9913 True-RMS AC model 0.5mA ~ 2A (according to User manual)
DCUU PM9911 True-RMS AC model 5mA ~ 20A
DCUU PM9912 this is AC/DC 5mA ~ 20A.
Both 9913 & 9911, they offer identical number of measured electrical parameters.
The named as F LED window, this is a host able to display another four electrical parameter.
In total a number of nine electrical parameters they are measured simultaneously.

DCUU PM9913 this become my choice, as I wanted to be able to measure Low-Power, Stand-By power.
DCUU its does offer data logging software, for all three models, but under a peculiar requirement.
They are selling (as option) their own communication interface for a connection with a PC.
This communication interface, has a VGA type DB15 as input, and the output it might be RS232 or USB, or RS485.
The converter to USB, this uses CH340 chip and a USB to serial port Windows driver required.
The name of data logging software, this is Electrical measurement system and it operates with the RS232 and USB options.
And in conclusion, at the price of the communication interface, they supply also and their software within a CD media.
Its DCUU instrument, comes with:
1) Quality control inspection card.
2) Calibration Certificate
3) User manual
4) Power cord
And here ends the quick presentation of these instruments.
