Decade Resistor Resistance Box DC Resistance Box ZX21E
The ZX21E rotary resistance box which has low zero resistance ,is used to adjust resistance in DC circuit. This equipment is commonly used in laboratories for schools, factories and scientific research units. The temperature of the air around should be +10℃~+35℃ and the relative humidity 30~80% when it is used .

The allowable current of each group resistance are shown in Table 1
The dielectric strength between resistance box circuit and shell can withstand 50Hz frequency,2000V AC, which lasts 1 minute.
The insulation resistance between resistance box circuit and shell is not less than 1000MΩ
Weight: 1.3 kg
Size : 200×150×110mm
Points for attention:
Please rotate each button first when you use the resistance box to confirm the contacting of the internal resistance is stability and reliability.
The current in the resistance box should not be more than the largest allowed current.
Please connect the wire with “0” and another small indication terminal when needing low resistance
The resistance should be placed in shadowing room. The temperature of the air should be +10℃~40℃, the relative humidity less than 80%,and there is no harmful impurities which can cause corrosion.
Packing list:
1 x ZX21EDC Resistance Box
