2. It is used to scale plate for various insulation resistance meters under production and repair.
3. It is used for calibration/check of megger.
4. It is standard resistance box of medium/high resistance.

Specifications
 

1. 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, resistance range is up to 1021111.1110MΩ, min. step value is 100Ω.
