Will this plug into my 869C? It has a circular female connection at the top with I think 4 or 5 pinholes.

Asked by: GabeF
Thank you for your inquiry. This RTD is supplied with no connector (stripped leads). The 869C handheld meter is supplied with the correct mating connector that you can solder to stripped leads in the field. All wiring instructions can be found in the 869C manual.

Two questions: 1.. Omega logger OM-DAQXL does not display calendar dates for 2023 or beyond. Is software update to help with this? 2.. To read the Air Temperature RTD-805, data logger pull-down RTD selection does not show RTD 805. Which selection?

Asked by: Dway
Thank you for your question. We will require more information to help on this question, please email the DAS team at DAS@OMEGA.COM
