1000 hrs. local CP5 dewar vapor pressure now 30 psig and heading toward normal. Mechanical level gauge for CP5 in agreement with current CDS indicated level, 60-65% full. LLCV needle valve strokes normally with presence and absence of instrument air. Oberserved needle %open in agreement with current CDS PID output %open -> Manipulated PID parameters to result in a PID output required to gain control of current CP5 level and returned control from manual to PID. Staged replacement part and tools needed to replace differential pressure transducer for CP5 but elected not to replace unit until work week. Will monitor from home periodically until then.
