I need to calibrate it ; of course I have the necessary calibrated DC and AC shunts
DCCalibrated at two output currents 0A and +10A, after that verified at -10A.
* 0V in, adjust R411 for 0A out
* +10V in, adjust R417 for +10A out
* Verify at -10V in / -10A out
ACCalibrated at 10A 5kHz.
* Compare DC and 5kHz AC at 10A by using a suitable shunt / thermal transfer standard. Adjust C424 for null on the thermal transfer standard.
