3.9 Front Panel mounted Digital Meter
The Digital Meter provides real-time Voltage and Current (switchable) output readings.
The front panel meter can be switched into two modes by pressing the black mode button:
1. Output Voltage of the welder in real-time.
2. Output Current of the welder.
During welding, the meter shows the current that is being delivered.
When welding stops, the meter will show the last Current that was delivered for a
period of 3 seconds, and then revert back to real time.
