Product Description
GF112 handheld single-phase watt-hour meter site verification
(Accuracy class 0.2/0.3/0.5) Application It is used to power grid
corporation measuring and testing center, power supply company
power supply management and energy metering department, national
levels measuring and testing institutions, also suitable for large
industrial and mining enterprises and property companies, etc
Introduction GF112 handheld single-phase watt-hour meter for the
verification is the scene of single-phase watt-hour meter on-line
detection accuracy and design. But in constant electricity, don't
take out stitches measure the electrical energy, power, current,
voltage, frequency and power factor, Angle. The accuracy of the
instrument adjusting rejected traditional methods of the
potentiometer + screwdriver, internal by single chip microcomputer
control, can not open the equipment in the case, through the button
to complete precision adjustment, so as to enhance the reliability
and stability. This instrument has small light, the function is all
ready, use convenient, beautiful shape, and other features, is the
ideal of single-phase watt-hour meter online testing instruments.
Main functions Checking various inductive, electronic type of
single-phase watt-hour meter error on site; Having the cumulative
power function, checking the single-phase watt-hour meter and LED
value; measuring voltage, current, power, power factor, frequency,
and electric parameters etc; To save 1000 group of measurement
data, convenient inquires the calibration data; With RS232
communication interface, and connecting computer on line to data
management; Optional current clamp 5 A, 20 A, 50 A ,100 A; To
measure CT ratio, measurement device than the integrated error.
