GDZX79D+ standard resistance box megger calibrator resistance tester calibration device

I. General information

GDZX79D+ standard resistance box is mainly used to calibrate various megohmmeters with a rated voltage of 5000V and repoint the dial during the production or maintenance of various insulation resistance meters. It is also suitable for the verification of insulation high-resistance meters and can be used as a standard high-resistance box for other circuits.

two. feature

l Metal film resistors are all produced by joint ventures. This type of resistor has the characteristics of low voltage coefficient, small temperature coefficient and good stability.

l Using the latest designed high-voltage resistant, high-insulation optical switch, the instrument has the characteristics of clear shifting and easy use.

l The resistance box adopts high insulation material and light pressure structure, so it has the advantages of small contact pressure, long life, small contact resistance degradation, and high insulation resistance.

l It adopts metal shell and has good electrostatic shielding effect.

three,.Specification

l Adjustment range: 0-121111.110MΩ, minimum step 100Ω.

l The maximum working voltage/current (reference voltage/current) and level of each decimal resistor board are as follows:

l When the maximum operating voltage or current becomes 1/5 of the maximum operating voltage or current, the resistance change caused by the change in voltage or current should not be greater than the corresponding grade index.

l Reference ambient temperature 23℃, relative humidity 40%~60%; nominal operating temperature 23±5℃, relative humidity 25%~75%

l Insulation resistance between line and shell ≥1×10¹²Ω

l The withstand voltage between the line and the shell (AC sine wave, 50Hz) is 8000V for 1 minute.

l Size: 490mm*249mm*171mm

l Weight: <15kg
