Came in a little early to run ETM Charge Measurements before Maintenance & followed the usual procedure. 

Log:  (Times in PDT)

• 7:20 Begin prep work for measurement
• 7:40 Began measurement (& went out to transition LVEA to SAFE)
• 8:22 Canceled out of measurements due to conflicting Maintenance activity.  So basically acquired 3-full data files (and a 4th data file was bad because I canceled out of it.)

Notes on the procedure/measurements:

• Step 1c: (HV values)  For both ETMs, the HV values remained less than 5V (vs the ~200V mentioned in procedure).  This is with multiple toggles of the HV ON/OFF button.  (NOTE:  ETMx actually did eventually get up to ~175V.)
• General Prep Note:  ETMx & ETMy look different.  ETMx ESD Coil outputs all have values, on order of 50k (vs. ETMy whose similar channels are all zero).  I don't look at these screens enough, but maybe this is due to how we use the ESD on ETMx and how ETMy continues to have a bad ESD (i.e. the LR).  I've attached a screenshot of both ETMs to show what I observe.   Again, this just may be normal, but for someone who doesn't put an eye on these screens often, it was just something I noticed.
• For ETMx measurement (see attached), the 2nd data file had errors, so I only had (2)  good measurements. 
• For ETMy measurement (see attached), had 3 good measurements (all with a "flat" LR which is due to our ill ESD).
• Matlab note:  Since I run this from my account, whenever I run the ESD_Analyse measurement, I select to "Change Folder" vs "Add to Path" when Matlab asks.
• Long Tred Plot (see attached) note:  made stop time:  2018,12,04,18,00,0
  • This gave me only plots for ETMx (see attached).
  • ETMx ESD Charge Eff Bias Trend showed only the Mean data point for my measurement.
  • ETMX ESD Actuatioon Strength Trend showed all the data points at 0.

Here are the original Slider Values (which I returned to after the measurement):

ETMx:

• Pit:  102.2
• Yaw:  -128.4

ETMy:

• Pit:  136.3
• Yaw:  -124.0
