HZJZ-III Arrester Monitor Calibrator

HZJZ-III Arrester Monitor Calibrator

With the continuous development of science and technology, the function of the arrester discharge counter is not only used to record the number of lightning strikes, but also to monitor the leakage current of the arrester online. Our newly developed lightning arrester online monitor calibrator is an instrument with both impact test and ammeter calibration.

II. HZJZ-III Arrester Monitor Calibration Device Ammeter Calibration

When the instrument is turned off, the wiring method forms a loop like the impact test. After connecting the wire, press the current-voltage switch before it can be turned on! At this time, the instrument is in the current output state.

During calibration, adjust the current adjustment potentiometer and compare the indicator on the dial of the instrument with the display on the dial of the sample to determine whether the current indicator of the sample is correct or not!

Suggestion: Perform rough calibration first, compare the accuracy of the large scale, and then adjust the current to within 2mA, perform accurate calibration, and determine the reliability of the test product!
