<div>Good morning Peter,<br>
<br>
Could you please let me know when the new 30V power supply will be installed on the IGH? We are now prep the dilution refrigerator for the coming run, and need to use IGH to control the fridge.
<br>
<br>
Thanks,<br>
<br>
Xiangdong<br>

Just to keep everyone in the loop we checked the power supply voltages, everything looked okay.<br>
<br>
The stepper motor that drives the proportional valve was spinning as well.<br>
<br>
We'll have to wait until Wei returns to do anything else since I'm not really sure what he wanted to do with the 30 VDC supply as nothing in the schematics calls for that voltage.<br>

> Before he went on vacation, Wei requested that I ask you to measure the voltage going to a proportional valve prior to the installation of this power supply. He'd like to see if it matches your previous measurements (taken before the installation of the
other new power supply). If you're not sure which valve this is, I can show you.<br>
