4656 2020-08-04 Factory none Disposed Disposed none The sensor was unrepairable and Campbell Sci disposed of it. Note from Campbell: "Sensor is shorted on the 12V input. Sensor is completely potted except for RH and Temperature components. Sensor cannot be repaired."
4647 2020-07-28 Lab none Shipped Factory none Sent back to Campbell for repair on RMA # 32280.
4629 2020-07-23 Lab none Tested Lab none Tested in the lab. I used a cable in the lab to power the sensor and measure its temperature signal with a volt meter. The reading was wrong and the base of the sensor definitely got warm. I same cable with another HMP60 and got a much more reasonable temperature reading and did not notice the sensor getting warm. The sensor needs to go back to Campbell for evaluation.
