View history entry 4629 for Vaisala HMP60 sn: L1740395

Date: 2020-07-23
From: Lab - none
To: Lab - none
Title: Tested
Notes: 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.
