Daily maintenance
1) The high-voltage switch dynamic characteristic tester is a precise and valuable device. Please keep it in a safe place when using it to prevent heavy falls and impacts. When using outdoors, operate under shade as much as possible to avoid direct exposure of the LCD screen to the sun for a long time.
2) When the instrument is not in use, it should be stored in a ventilated room with no corrosive gas at a temperature of -10 to 40°C, a relative humidity of no more than 80%. In humid seasons, if it is not used for a long period of time, it is best to turn on the electricity once a month for about two hours each time.
important hint
1) Sensor and grating
· The sensor is a precision device, especially the 0.1mm sensor is equipped with precision optical glass. It should be prevented from falling from a height or impact during installation.
·The high-voltage switch dynamic characteristic tester stipulates that the grating moves from the bottom surface to the top surface of the sensor as the closing movement direction, and vice versa is the opening movement direction. During installation, it should be kept consistent with the direction of movement of the moving contact.
2) Power supply
· In order to ensure the normal operation of the rectifier power supply and the operation command sampling circuit, when using the internal DC operation power supply, make sure that the control terminal and negative terminal of the switch's opening and closing coil are completely disconnected from other secondary circuits.
