Hello
<div><br>
</div>
<div>we are looking at a pump exactly the same as the one you have in CONNIE.</div>
<div>The only way we can get the turbo pump to spin without turning ON the backing</div>
<div>pump is by disconnecting the AC power to the backing pump.</div>
<div><br>
</div>
<div>We can imagine two ways to do this.</div>
<div>1) loose ac plug to the backing pump. See the grey cord in the attached picture, it should have</div>
<div>a latch holding the plug in place.</div>
<div>2) the green I/O switch on the backing. This switch could be hard to see, look at the attached</div>
<div>picture.</div>
<div><br>
</div>
<div><br>
</div>
<div>Questions:</div>
<div>1) does the turbo pump get to full speed?</div>
<div>2) what is the vacuum gauge measuring?</div>
<div><br>
</div>
<div>Thanks,</div>
<div>Juan<br>
