Run Number	Date (time)	LED voltage	High voltage	Events
130200..... 1 means with amp display	Jan-14, 12:04	8 V	1040 V	120 k

Fixed most channels: (-11,-17) bad cable, (-11,17) unstable amplitude (replace divider), (18,17) and related (replace flash adc, rocecal1, slot18), (-16,2) and (-16, 4) replaced dividers and reconnect PMT, (-14,2) secure divider connection

This is a reference run, when all waveform look Ok
