Buttons will do.
is the reverse ADC sampling value, SWR is the current standing wave.
When testing the minimum starting power of QRP radio, please pay attention to the FWD ADC sampling value in the bottom row.
After entering the function test interface, the program will detect the relay switch from left to right in turn, and manually observe the battery voltage.
The voltage value or judge whether there is a fault according to the sound of the relay pulling in.
In the state of automatically switching the relay, the current switching state of the relay is continuously monitored. Please press and hold the button to realize the temporary
After entering the function test interface, the program will be displayed in real time according to the correction value set by the user.
Among them, BAT is the current voltage and the remaining battery percentage, FWD is the positive ADC sampling value and power value, REF
Stop and enter the next relay test, and realize the continuous current relay pull-in test. If you want to continue to test the next one, press and hold
This function is mainly used to detect the status of the relay and troubleshoot the relay.
