HPAL IAI B
7.6.18
This procedure calibrates the IAI Board for High Power Active Load.
This procedure requires maximum voltage 5.0 V and maximum current 30
Amps.
Power supply connected to IAI board needs voltage rating of 0 to 10.0 V.
1. Connect the shunt and the DC current meter between the active
2. Connect the second power supply to the IAI board. Also connect a
3. Set the input voltage to 5V (First power Supply connected to the
4. Turn the active load unit
5. Set the mode of the active load to external input mode or IAI mode
6. Set the second power supply (Power supply connected to IAI Board)
7. After the DMM voltage stabilizes enter the voltage of the DMM
Note: This voltage should be equal to 0Volts.
