Product description:
I. overview
Alternating current (voltage) is a transmitter can be measured AC current (voltage) into the instrument according to the linear ratio of the output DC voltage or DC current, widely used in electric power, telecommunications, petroleum, coal, metallurgy, railway, municipal and other departments of the electrical device, automatic control and scheduling system. AC current and voltage transmitter have single -, three - way combined structure:
1, high accuracy (typical: 0.2% best 0.05%).
2, the entire range has a very high linearity.
3, a high degree of integration, simple structure, excellent temperature characteristics and long-term stability of the work, so that the transmitter from the regular calibration.

Six, product debugging
1, YWD, YWE single AC current, voltage transmitter: to find corresponding to the transmitter panel corresponding to the ZERO and CAL two debugging holes
Inside the two potentiometers are zero and full adjustment potentiometer, adjust with a small screwdriver slowly rotating to the required accuracy can be.
2, YWD, YWE three AC current, voltage combination transmitter: find corresponding to the transmitter panel corresponding to ZEROA, CALA,
ZEROB, CALB, and ZEROC, CALC six debugging holes, the potentiometer in the A, B, C three, respectively, the zero and full adjustment potential
When the utility model is adjusted, the utility model can slowly rotate to the required precision with a small screwdriver.
