* I think there is a hydraulics fault. The Live page keeps saying to and keep getting command 'previous source in sched not reached before new source was commanded' (Lucas). | * I think there is a hydraulics fault.

- | * 22:11 UT - Tsys values all over-flowing due to cal not running. Some confusion during setup as Lucas did half and Jamie did half. (Ellen) | + | * Hydraulics fault was caused by circuit break as the motor wasn't covered and water got in. Collaborative effort of Eric and Brett solved the problem. (Lucas). |
+ | * GPIB device continues to time-out, however delay difference is still stable and < 0.3. Counters are being monitored on rack camera to make sure that severe drifts don't occur whilst Eric investigates. (Lucas). | ||
+ | * 23:50 UT - schedule resumed, lost about 500 GB. First scan 295-2351. GPIB still a problem though, reporting massive delay differences every scan. Clkoff value looks reasonable. (Ellen) | ||
+ | * 01:04 UT - Eric has reset the GPIB device and it is still a problem. (Ellen) | ||
+ | * 01:11 UT - Tsys values all overflowing again, restarted CAL again and everything is fine. The CAL has dropped out like this halfway through an experiment before. (Ellen) | ||
+ | * 01:22 UT - Jamie has turned the GPIB off so that we are no longer measuring a delay difference because it's wrong anyway. Keeping an eye on dbbc=pps_delay instead. (Ellen) | ||
