keyword=IA slope calibrationI have done a IA scan before the polarisation measurement :
run#.................volt................Aq
1182 5 -192+-27
1183 9 350+-26
1184 7 84+-18
1185 3 -462+-19
1186 1 -71+-21
The slope is ~130 ppm/volt (see figure below).
It is almost 0 for 6.5 volt setting. MCC has set to 6. ( that's the readback I have)
Anyway it is enough to start the feedback loop.
1187 6 -40+- 25
Waiting now for higher current to start the feedback loop.
