Three-phase energy meter field calibrator
TT
Support U disk: download calibration data through U disk, and serial port upgrading
software.
TT
Communicate with the PC, very easy to interface with the original database and
management system.
HDGC Meter Management System
software can be equipped to
realize paperless office.
TT
High-brightness, high-definition, high-resolution 5.7 "(320 * 240) TFT color LCD display.
TT
Chinese character input.
TT
Wide range of power supply AC 57.7 ~ 480V, and an internal battery can supply power (no
external battery charger for charging) double selection.
TT
The system uses a high-speed high-precision digital multiplier, which can measure active
(reactive) power, voltage, current, frequency, phase, and all other parameters at the same
time, and can correct all the parameters by software.
TT
The instrument has no potentiometer, which can completely prevent instrument error from
changing caused by transport and other outside factors, thus greatly improving the system
stability and reliability.
TT
The system uses domestic pioneering digital true reactive measurement technology.
Reactive measurement can be truly affected by the voltage and current, phase asymmetry,
frequency change and others, so the reactive accuracy is raised to 0.1% for the first time in
