VI. Product Calibration
1. Calibration environmental conditions
The calibration environmental conditions and requirements are as follows:
a) Environmental temperature: 20
℃
±5
℃
b) Relative humidity: 30-60%
c) There is no measurable electrical field, magnetic field as well as positive and negative irons around.
d) There is ground wire and the resistance of ground is
＜
100Ω.
2. Equipment for calibration
The instrument and equipment for calibration should be calibrated by the institution of metrological
technology, which should meet calibration use requirements within the validity period.
The main calibration equipment mainly consists of DC high voltage meter, DC high voltage power supply,
standard plate electrode and distance regulator, etc. The sensor is placed on the central line of the
calibration plate and the block diagram of the calibration device for the non-contact electrostaticvoltmeter
is shown as follows:
