Panel Description
Tester panel schematic
1. Pulse method indicator: green diode, green light on after power on, the working state in the pulse method test state.
2. Flashover method indicator: red diode, when the working state is in the high pressure flash sampling state, the red light.
3. Multiple times method indicator: red diode, when the working state is in the state of multiple pulse sampling, the red light is on.
4. Charging socket: Please use the dedicated DC12V3A power adapter.
5. Output amplitude: Used to adjust the input and output pulse amplitudes. When in use, adjust according to the waveform displayed on the screen. If the adjustment is too small, the pulse reflection is very small, or even cannot be sampled, as shown in the figure below (left). If the adjustment is too large, the reflected pulse is connected to the baseline without intersection, and the baseline may even become a slash, as shown in the figure below (right). Generally, before sampling, the input amplitude knob is rotated about 1/3, and then adjusted according to the size of the sampled waveform and resampled.
6. Output socket: The instrument uses a 9-hole aviation socket, which is the communication control port between the tester host and the trolley.
