Structural features of S50
To turn the clips are (terminals) on the back of the unit. Right clamp isolated from the inner electrostatic screen porcelain bushing and connected to the stationary electrode. The second terminal is connected to the movable electrode and the screen. Voltmeters S50 to limit e from 30V to 450V have a third terminal connected to the protective resistor connected to the second terminal. The device is protected from outside influences protective screen.
In front of the voltmeter S50 located: plug strip for power supply and plug the clarifier switch for switching power supply clarifier scale. On the cover of the device is the head of the corrector.
Voltmeter S50 is available in odnopredelnym to different final values of the working scale. All values in Table 1 is fed.
S50 electrostatic voltmeters have a low energy consumption. Devices on (30, 75, 150, 300, 450) are in the protective resistors, protecting the measuring equipment from being damaged by accidental circuit between the moving and fixed electrodes in the clean and jerk and overload.
S50 voltmeters are designed to work indoors at ambient temperatures from -15 ° C to +35 ° C, relative humidity of 80%. The instrument is sensitive to shocks and vibrations. When you work with devices up to 450V to 220V AC at a frequency of up to 300kHz measured voltage is recommended to include a protective resistor.
