Blew out DPR and DPL through the flags. DPR came up good. Seems a little off but we will see in flight.
Found one of the cotter pins had fallen out of the aft window. Replaced with suitible metal object.
A/D Auto cal stopped at 24% for some reason. We need to look at this since it has not worked since RF01.
60 Hz left voltage meter read low when powered up. A tap brought it back to 116V.
BO 1500
TO 1527
Long wait to get the runway.
1534 Dew pointers responding much better today.
1609 A/D cal was still on. Used A/D test to get it turned off. Reading good from this point. ALL A/D Channels were messed up and had a 0V input.
ALL ANALOG DATA PRIOR TO 1609 IS NO GOOD. ANYTHING THAT DEPENDS ON AN ANALOG CHANNEL IS NO GOOD ALSO UNLESS POST PROCESSED.
If an Auto Cal hangs up the Tech needs to got to the Test A/D pager and make sure that all channels are set to OFF. If not they will be hung at a value.

DPR and DPL both Flashing service mirror. Plane was cold soaked. Turned off until after takeoff. To hot an muggy
BO 2228
TO 2231
2235 DPL and DPR sensors back on.
Starting down

WIKI NOTE
Recommendation will be to use variable names for most sensors in logs that will make searching for comments easier.
