keyword=HAND N3-3R ADC & TDC low for Run 21878The N3-3R PMT is giving a low signal for both the ADC and TDC as shown below. I checked the HV and it looks good (readback -1512.5 V, -536.1 A). Not sure what happened with it. This is the first run this morning where it happened. Keeping an eye on it to see if this continues.
