The voltage being read back by the cRIO is ~4V which is being converted correctly to ~400 torr.</div>

Can you get the full model number of PT334 so I can better give some suggestions on what you guys could measure to help troubleshoot?</div>

Off-hand some of the things that could be wrong is: the sensor not getting proper supply voltage, a loose connection of the output to the cRIO as it is getting some voltage back, or a bad sensor (let's hope it isn't that as that was the only one we had in that
range).</div>

<div class="">Hello Brian,</div>
<div class=""><br class="">
</div>
<div class="">RTPC abs. Pressure transducer seems not working properly. This should show around 760 torr (~ 1 atm), but showing about 400 torr only. What could be the reason?</div>
