Three-phase energy meter field calibrator
Introduction
TTThank you for using Our company HDGC energy meter field calibrator product.
TTThe handheld three-phase energy meter field calibrator is a series of Our company’s products,
and is a product integrated with low-voltage energy meter calibrator and low-voltage metering
device calibrator. It can not only measure high-voltage energy meter and wiring, but also measure
the integrated error of low-voltage measuring devices, as well as TA transformation ratio, TV and
TA secondary load. Such an instrument is equivalent to several instruments.
TTBefore this product is used for the first time, please be sure to carefully read all the
information accompanied with the instrument, which will help you make better use of the product.
If you fail to operate this product according to the instructions and requirements of this manual, or
