Product Description：
Description:
ZX21 series rotary resistance box for the DC circuit for use adjustable resistance, has a lower value of zero resistance, are all the most commonly used laboratory instruments for schools, factories and research units for electrical measurements and other experiments. ZX21 series rotary resistance box is suitable for ambient air temperature + 10 Degree~ + 35 Degree and relative humidity when using 30 to 80%
Parameter:
Use for precision resistance experiment: 0.1R to 99.9999KR
Zero value of the resistance: 30 ± 5mΩ
Dielectric strength of the resistance box circuit between the shell, withstand a frequency of 50 Hz, 2000 VAC's role, which lasted one minute
Resistance box circuit and the insulation resistance between the shell less than 1000 megohms
Size: 200*150*110mm
Net Weight: 1.3kg
Note:
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
Package includes:
1 x Set of ZX21 DC Resistance Box
