My USB connect to a rev1.1 board appears to be failing.
It was working, and now its stop connecting to the PC, stops even causing an audible ding.
If I take the same USB C cable and plug it in to the USB C of a Rev1.0A3 it sometimes works. Usually causes an audible ding, but sometimes doesn’t appear as a com port.
I’ve rebooted my PC twice, and…[Read more]

The CTD does not allow an internal calibration, but we do a calibration in the lab with conductivity standards and apply the calibrated data as a calculated variable.
This is maybe semantics, but the Mayfly wouldn’t be a source of quality (or the lack thereof). That’s the sensor’s job. CTDs are usually pretty durable.

Hi,
Our Mayfly 0.5b has been redeployed after sitting in storage for more than a year. Yesterday I downloaded a week’s worth of data and I’m wondering how to tell if it is accurate and that the CTD probes are working as they should.
From a quick scan of the data I’ve noticed a few things.
