DG started the topic Mayfly data logger -9999 in the forum Mayfly Data Logger 1 months, 2 weeks ago

CDT sensor reading on Mayfly monitor reads -9999. Unable to find any issues with sensor, wires. Can’t figure out how to disconnect Grove cable in order to disconnect and reconnect, as per instructional video. Don’t know what a “headphone jack” looks like!

HELP!
