Lakeshore Temperature and Heater Settings

The Lakeshore temperature controllers must be reset after a power failure or power down of the instrument.

The default setting on power-up is to display the temperatures being read, but the heaters will not reset and must be reprogrammed.

The labels on the Lakeshore are correctly labeled, and version 1.801 of the HKP is also correct.

DET H: The H-band detector is on Channel A and should have a setpoint of 65.2K. Heater power should be set to MED.

2ND Cold Head: The first cold head is the warmer of the two stages, is shown on Channel B, and has no heater or setpoint. Should say OFF.
