Naoki, Daniel, Sheila, Camilla
Naoki found the OPO would not lock like usual. After he locked it on green there was no CLF_REFL_RF6 signal. After checking settings, we followed 73801 instructions to measure the NLG (17.8). In doing so, found we needed to adjust the OPO temperature by 0.15degrees. After this OPO temperature adjustment, it locked fine. Daniel swapped thermistor readouts today that effected this even though the requested and measured OPO temperature were the same before and after, 74188.
Note that now the OPO LOCKED_SEED_NLG guardian state goes though LOCKED_CLF_DUAL (needs a locking OPO), we first dropped the CLF RF threshold in half (via SQZ Overview > HAM7 > OPO IR > OPO PZT1 > H1:SQZ-OPO_IR_RESONANCE_CLF_NOM), now reverted.
Since we doubled up terminals, the terminal for the OPO thermistor physically changed. The resistance reported by the OPO thermistor changed by about 45Ω, whereas the EL3692 measurement error for the 10KΩ range is 50Ω. This seems within the expectation.
