| miniDOT 1220 | 2019-06-13 | Lab none | Tested | Lab none | Tested but we probably can't use this sensor any more. We put in new AA lithium batteries, and the miniDOT was able to power up, but the LED light continuously blinks 2x, "card error." We tried re-formatting the card, using another 2GB card previously used in a miniDOT (could have been a bad card), and then with a good SD card at EE. In all cases, the LED status light still indicated a "card error." |
| miniDOT 1220 | 2019-05-23 | Mayberry DO Sensor E | Removed | Lab none | Brought back to the lab for testing. The o-ring was warped and it was damp inside. There was some corrosion on the board and the batteries were dead. |
| PTB110 E1330045 | 2019-05-23 | Mayberry Barrometer | Removed | Lab none | Reading dropped down to 50, so removed and brought back to the lab for inspection. |

| LI-7550 AIU-1866 | 2019-05-31 | Factory | Received | Lab none | Received back from Licor. They replaced the RF chip in the power supply. |
| HMP45AC T2130005 | 2019-05-22 | Lab none | Tested | Lab none | I removed the power cord and soldered on an extension cord. Tested in the lab with radiation shields and fans, and compared well with two HMP60s sn L1740398 (Campbell has OK'd this one) and sn G4540023. This sensor is probably ok, but maybe we can test it with a reference AirT/RH sensor from AMP. |
| CS451 70011234 | 2018-12-10 | Lab none | Tested | Lab none | Tested in both air and water in the lab and saw an offset of about +0.975 cm. See RT report "Pressure transducer comparison 12-2018." |
| CS451 70011229 | 2018-12-10 | Lab none | Tested | Lab none | Tested in both air and water in the lab, but saw diurnal fluctuations of only 0.1 cm, not the 5-6 cm we saw in the field. See RT report "Pressure transducer comparison 12-2018." |
| CR1000 47108 | 2019-05-28 | Sherman Barn Data Logger Met | Notes | Sherman Barn Data Logger Met | VX2 may be unreliable. NR01 PRT was drifting constantly until it was re-wired from VX2 to VX3, but that could also have been a wiring issue with another channel. |
| AM16/32B 11662 | 2019-05-28 | Sherman Barn Multiplexer Met | Notes | Sherman Barn Multiplexer Met | Channel 28 and 32 are probably bad (see field notes from SB 2019-04-11). |
