Description

technical field

[0001] The invention relates to a multi-channel DC high-voltage microammeter. Background technique

[0002] Most of the existing DC high-voltage microammeters are single-channel, that is, one microammeter can only measure one current at a time. With the change of use scenarios, the diversity of use requirements and tests, this single-channel microammeter is increasingly unable to meet the current test needs. At present, when using a single-channel microammeter to perform complex experiments, several microammeters need to be used at the same time, and several microammeters are required for several measurement points. In this way, the display positions of the microammeters are many and scattered, and it is inconvenient to observe and record, which affects The overall progress of the trial trial.

Embodiment Construction

[0019] like figure 1 and figure 2 As shown, preferred embodiment one: a kind of multi-channel DC high-voltage microammeter of the present invention includes at least two measuring modules 1 for measuring current respectively, a display module 3 for collectively displaying the measured current, The processor 2 and the power supply module 4 are used to read the measurement data of the measurement module 1 and transmit the measurement data to the display module 3 after processing. The output terminal of the processor 2 is connected with the input terminal of the display module 3 . The power supply module 4 is electrically connected to the processor 2 . This embodiment uses eight measurement modules. Each measurement module 1 forms a communication channel with the processor 2, that is, eight measurement modules 1 and the processor 2 form eight communication channels. The processor 2 performs data communication with the corresponding measurement module 1 through the communicat...
