View history entry 5035 for Campbell Sci. CS547A sn: 5688

Date: 2020-12-11
From: Lab - none
To: Lab - none
Title: Tested
Notes: Tested in the lab with both Campbell interface and homemade interface sn 547-01. In either case, the temperature read high, around 40 degC when it should've been around 20-25 degC. I unwrapped an old splice in the cable, but it looked perfectly fine, so I think the temperature sensor is just bad. We can still use this sensor in the future, but we'll need to be careful to do the temperature correction with another temperature sensor in the water (e.g., from water level sensor or a water thermocouple).
