I've bought a 9 pin on/on switch for my RTD sensors to add on to my panel, but will the added resistance in the wire I add plus the switch mess up the readings of the sensor?
The K type I'm using is for the wire only not the sensor. I wired it up last night but unfortunately the readings are out. I've determined it's the switch itself that's the issue, or possibly the grounding of it to the box? The reading goes way up or down when you touch the switch at all, yet along actually switching. When left alone, for the most part it was reading 10°F lower than the actual temperature. I do have another switch on hand to replace that one if needed
