I observe that the lumi scaler rates drops below offset(V-to-F has an offset of 200kHz) with beam. All the lumi signals seem to respond to the beam current and HV changes, which is good.
The I-to-V amplifier have a inverted/non-inverted switch on it. Earlier I had all of them to be non-inverted. Now I changed channel 7 and 8 to be inverted, just to see if the scaler rate goes above 200kHz offset with beam.
