6940	2024-10-23	Lab none	Installed	Gilbert Tract Flowmeter ADCP	Installed in the GT channel after cable repair
6920	2024-10-16	Lab none	Adjusted	Lab none	The ADCP was complaining about too many files, so I downloaded the last 2 files and deleted all of the files by formatting the sensor. The configuration is not affected by the reformat, but I made 3 changes to the configuration so we don't have to "re-calculate flow" before exporting the data. Use SNR to adjust sample volume: Enabled --> Disabled Instrument z (m): -2.220 --> -2.280 Initialize volume: Continuous --> Reset
6919	2024-10-15	Lab none	Repair	Lab none	Joe repaired the break in the cable. He also re-repaired an old break that was previously soldered in the field. Both breaks are now covered with adhesive-lined heatshrink. The entire cable is now protected with flexible metal conduit.
