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.
Residual resistance <0.1Ω, variation <0.01Ω
Referential ambient temperature is 23℃, relative humidity 40%~60%; nominal operation temperature is 23±5℃, relative humidity 25％~75%
The insulation resistance between line and the enclosure>1×1012Ω
The withstand voltage (AC sine wave, 50Hz) between line and the enclosure is 8kV for 1 minutes.
