Product Description
HVHIPOT GDZX-79F DC Decade Resistance Box Megger Calibrator
GDZX-79F Standard Resistance Box for Megger is 1 million MΩ rotary resistor, designed to calibrate megger, with the features of wide adjustment range, easy to use.


Features
Specifications
This resistor is composed of two parts: First part: 9pcs decimal electrical resistance panels in series, that is, 11×10KMΩ+10×(1000M+100M+10M+1M+100K+10K+1K+100)Ω
Second part: 9pcs 100KMΩ fixed resistor in series.
If two parts are in series, the resistance range is up to 1021111.1110MΩ, min. step value is 100Ω.
Max. Voltage/current (referential voltage/current) and class of every decimal electrical resistance panel is shown below:
