The most common place to find this is at the tip of the thermocouple whereby the twisted pair junction needs to be re-made. Ideally the junction should also be welded using a…
Question: On occasion one of the channels on my Kaye Validator 2000 data logger reads “UNDER” or “OVER”, what’s the cause of this?
Answer: Typically a channel will read “UNDER” or “OVER” when water has entered the SIM of the Kaye Validator 2000 data logger and the cold junction has become wet. Check each thermocouple wire to ensure that you have added drip-cuts to each wire 1m from the SIM to allow the condensate to drain away from…
