– Current control:
The current control provides a safer and more accurate control of the
furnace intensity.
• Set the jumper J2 to B1-B2.
• Connect a digital multi meter on TP1 (TP15 is GND).
Adjust only, while the furnace is active:
• Start the analysis, adjusting P2 until 6.3V DC is reached on TP1 (for copper
analysis adjust 1.2V DC).
The following diagrams show the relationship between the set value (adjustment
with P2 on the HF 42 board) and the generator parameters.
