<br>
The EEL/108 setup will be idle tomorrow, so that is a good time to run<br>
some tests.<br>
<br>
Right now there is only one LV cable plugged into the MPOD crate<br>
(top-left location in the EEL/108 racks). I turned the LV off for all<br>
channels just now, so you are welcome to just unplug the cable from the<br>
front panel and proceed with your tests.<br>
<br>
NOTE: The channels are configured use use the sense lines for voltage<br>
regulation so you will likely have to toggle the setting to use the<br>
'internal sense' lines so it regulates against the terminal voltage<br>
or it will just throw errors with the cable unplugged.<br>
<br>
I should be on-site after 10am tomorrow (Wed) and should be free to drop<br>
by if you run into any hardware issues. You can reach me via Teams or<br>
on my cell 757-344-2494.<br>
