6413	2023-09-18	Lab none	Loaned	Loaned none	There are a sticky note claiming this one was sn 243? Loaned to Gracie Pearsall at UCSC for a informational display at Elkhorn Reserve
4540	2014-12-10	Twitchell Rice Heat Flux Plate A	Removed	Lab none	Removed from TW and brought back to the lab for troubleshooting
1630	2014-11-25	Lab none	Installed	Twitchell Rice Heat Flux Plate A	Installed in multiplexer on channel 16. The heat flux plate was reading INF, so this needs to be looked at next time—I couldn’t diagnose the problem.
1631	2014-11-21	Lab none	Repair	Lab none	There was a break in the insulation and glue near the plate where it had been repaired before. I cleaned up the plate, re-spliced the wire near the plate and sealed the connection with black silicon. It seemed to be functional using a voltmeter and heat.
1629	2014-11-16	Twitchell Rice Heat Flux Plate A	Removed	Lab none	SHFP1 was removed from rice since reading INF. Joe will diagnose in lab.
1341	2013-06-07	Lab none	Installed	Twitchell Rice Heat Flux Plate A	Installed to replace the one cut off by a tractor (sn 00244). Installed in AM25T channel 16 (SHF1).
1340	2011-10-27	Twitchell Rice Heat Flux Plate B	Removed	Lab none	Joe checked the wires on the SHF plates and found that they were rotting away. Brought back to the lab to fix.
1339	2009-04-03	Lab none	Installed	Twitchell Rice Heat Flux Plate B	Installed at the rice as SHF2 in channel 17 on the multiplexer. It's calibration coefficient is: 62.1 micrV/(W m-2)
