Sheila reported an issue with the PMC transmission monitor which had shown a bogus low power readout (see alog 9120).  Since I happened to be in the PSL room this morning, I unplugged and plugged the lemo cable of the PD to see what was going on. For some reason, it fixed after I plugged it back. It now reads the correct power of about 11 W. Also, I could not reproduce the low power state by wiggling or unplugging/plugging the lemo cable. This is exactly the same situation as before (see alog 8622).
