HFP01 000138 2024-03-07 Tonzi Heat Flux Plate A Maintenance Tonzi Heat Flux Plate A We dug this plate up to replace its cable that had all its insulation rotted off. The plate was 2-5cm below the surface – it was tilted and ground surface was not very flat. We put it back flat at 3cm and the new cable in conduit.

HFP01SC 00068 2024-02-16 Tonzi Heat Flux Plate D Maintenance Tonzi Heat Flux Plate D I dug this plate up. It was at about -10cm with voids below the plate. I soldered on a new cable amd cut off the calibration cable because the insulation on both was completely rotten. I put it back at -2cm.
EXO2 22C103416 2024-03-06 Factory none Received Lab none Received wiper sn 13A100277 (firmware 1.0.86) from YSI after repair and calibration. Came with an extra brush and a small allen key for installing the brush. The factory inspection reported that water had leaked into the probe housing and all internal components were corroded. They replaced the wiper under warranty. YSI recommends sending the wiper back to the factory every year to have wiper motor o-rings replaced and lubed to prevent water leakage.

He sprayed the bolts and bolt holes with a anti-corrosion spray before I installed it again. The 7550 temperature sensor was bad. I replaced with a repaired homemade temperature sensor. The HMP fan was not spinning, but it seemed to work fine after I removed a bit of fluff.

This was not previously recorded in the equipment entry, and Campbell did not have any record of it either. Incontrovertible proof that we should never throw anything away.

HMP155 T2820180 2024-01-25 Factory none Disposed Disposed none Campbell's evaluation:
Inspected. Cap filter is dirty and sticker labels started to peel off suggesting sensor has been deployed in a very humid environment. After tests sensor showed problems to provide correct RH and Temp data. Unfortunately sensor can't be repaired or calibrated. Warranty expired o 08-27-2022. NOTE: We suggest to acquire a new unit such as the HygroVUE10, which offers advantages worth look up, as a replacement for the damaged one.

Dead unit will be returned so that I can take it apart!
HMP155 T2820180 2024-01-17 Lab none Shipped Factory none Sent to Campbell on RMA 37957. RH and AirT are reading zero.
EXO2 22C103416 2024-01-23 Lab none Tested Lab none The wiper hasn't worked properly since being installed in mid-December. When we pulled the sonde last week, the brush was parked over the pH sensor and all the sensors were dirty. I brought the sonde back to the lab for routine calibration and tested the brush. The brush did work smoothly as first, but then it became intermittent. Sometimes it didn't work at all and sometimes it worked only in spurts (and the EXO would disconnect from the laptop right before the brush moved). The wiper did not show up under the Sensors or Calibration tab. Nothing changed when I tried plugging the wiper into a different port. I talked to Matt at YSI who thinks something is messed up electronically inside the wiper--it can receive commands (to wipe) but is not talking back to the sonde. I will send the wiper back to YSI for repair.
