Yesterday Nustinee and I installed the Hartmann Sensor RTDs that measure the temperature of the Hartmann plate. Temperature changes in the Hartmann plate couple directly to spurious spherical power signals. These sensors,
D1101935, will allow us to subtract this component.
When we plugged the sensor into the Plate Temperature port on
D1200934 we saw no signal on the HWS MEDM screen. We discovered later that this was because the MEDM screen was not showing the correct channel; the Plate Temperature port is working just fine. However, we have temporarily plugged the Hartmann plate sensors into the Air Lens Temperature port. We’ll fix this tomorrow morning.
The channels corresponding to the Hartmann plate temperature sensors are:
H1:TCS-ITMX_HWS_TEMPERATURESENSORPLATE
H1:TCS-ITMY_HWS_TEMPERATURESENSORPLATE
Everything has been plugged to the right port. The read out seems reasonable. The medm screen now have the right channel on HWS Plate Temp.
H1:TCS-ITMX_HWS_TEMPERATURESENSORPLATE has been reading a nonsence value of -200 since 2019-08-06 (alog 51087). When work on / move the table in the future, we should check this tempurature sensor is working.
