Resistance Box

Resistance Box 

Gelsonlab HSPE-105 High Precision Variable Decade Resistor Resistance Box Knob Switch for lab 0.1R to 99.9999KR

When the proper use of resistance box to rotate the knob in each group, so that the contact resistance is stable and reliable
The maximum allowable current value of the resistance box in use should never exceed the specified
When only a small change in resistance, then wire to the "0" and another small indication terminal, can reduce the resistance inside the lead resistance
The resistance box should be placed in shelter room, the air temperature from + 10 Degree~ 40 Degree relative humidity below 80% should not contain harmful impurities can cause corrosion
