Q1: When HFP-800 sets parameters, the window display content is not related to the content marked on the front panel of the device
A1: The four windows on the front panel of the device are as follows:

Four Windows On The Front Panel

During the test, the contents displayed in the window are consistent with those marked on the front panel. During the test, the window display definition (from left to right): output voltage, lamp voltage, lamp current, lamp power/output frequency.
The HFP-800 hardware has been improved, and the test parameter settings are slightly different. The old device is set as follows:
When setting parameters, the window display content is not related to the content marked on the front panel. When setting parameters, the window display definition (from left to right): no meaning, lamp open circuit voltage or starting voltage, no meaning, lamp rated voltage or working voltage.
The new device settings are displayed as follows:
