High Accuracy And Quality Watt-Hour Meter Calibraotr,New Product And Hot Sale
INTRODUCTION
The device is equipped with thigh resolution TFT color LCD. The Reference Standard is used to test single and three phase meters, instrument transformers and installations on site.The unit can be used with various types of clamp-on CTs and current and voltage sensors. Therefore, it is possible to easily and accurately test both CT/PT and direct connected meters.The GF312V2 electronic working standard is a precision measurement unit for all AC values that are used in the measurement of energy. It impressive trough its small dimensions and light weight. The wide measurement range, high precision and excellent immunity to interference are the outstanding features of this instrument.
