<p style="margin-top:0;margin-bottom:0">We will have to check out these two load cells once we have better access to the solenoid. I'll speak to Denny.</p>

<p style="margin-top:0;margin-bottom:0">Would you mind logging all this info in the log book - if not already done - really useful trend data.</p>

Following up on the email sent in October 2018 on load cell trends for the Hall B Solenoid, attached are plots showing the Solenoid's load cell readings since January 1, 2019.</div>

As in October 2018, the plots are colored to indicate the power status of the Torus and Solenoid:</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Blue: Solenoid ON, Torus ON</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Green: Solenoid OFF, Torus OFF</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Pink: Solenoid ON, Torus OFF</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
Red: Solenoid OFF, Torus ON</div>

<div style="font-family:Calibri,Arial,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
All LC plots have areas from about April 24 - April 25, 2019 where the readings went to 555 lbsf that can be disregarded. This period was when the LV cRIO froze and stopped communicating with the PLC.<br>

In general, the LCs are stable. As expected, the biggest changes are seen when both magnets are ramped. This was also seen back in October 2018.<br>

When the magnets were both tested in negative polarity on April 18, 2019, there does not appear to be any difference in LC readings.<br>

There are two LCs (RS86103DS_BR_T and Z86108US_BL_B) that have read zero lbsf since my last email in October 2018. Have these LCs been verified to be working correctly?</div>
