Residual voltage test device
This device is designed and manufactured according to the test requirements of Section 22.5 of the GB 4706.1 standard for the measurement of the residual voltage of the appliance plug. The equipment adopts an aluminum alloy case with a timer, which can set how long it takes to measure the residual voltage after the power is disconnected. The oscilloscope required for the measurement of residual voltage needs to be provided separately by the customer.
