Rotating resistance box manufacturer

1Rotating resistance boxPrecautions for use:

1. When using a resistor box correctly, the knobs of each group should be rotated first to ensure stable and reliable contact of the internal resistance.
2. The resistance box should never exceed the maximum allowable current value specified during use.
3. When only a small change in resistance value is required, connecting the wire to the "0" and another small indication terminal can reduce the lead resistance inside the resistance box.
4. The resistance box should be placed in a shielded room, with air temperature ranging from+10 ℃ to 40 ℃ and relative humidity below 80%. It should not contain harmful impurities that can cause corrosion.

2. Under reference conditions, if the temperature and relative humidity exceed the reference power range, but within the nominal power range, the additional error caused by power changes should not exceed the corresponding level index value.

The insulation resistance between the circuit of the resistor and the metal shell should be greater than 500M Ω.

4. The circuit of the resistor and the metal casing should be able to withstand an AC voltage of 2000V at 45-65HZ for one minute without breakdown.
