We're using LabView....but this was the fix. Setting that to 60Hz in Instacal and then restarting LabView. We saw good values while it was running (at least from what we could tell). Can you explain why "Data Rate" is a noise filter? Does it not say to the unit "Collect this fast"? Because the plan is to buy the extender and then connect around 30 sensors to this unit. Will that in any way prevent us from collecting at around 5hz (each channel) data collection? Can we set different DataRates for different channels (Thermocouples to 60 S/s and Voltage based sensors to probably 1000 S/s) and enables us to collect data faster.

Hi there, we went and tried out your suggestions. We still see the issue when the cartridges are engaged. I've attached a graph and instacal settings.

Greetings, I'm having an issue with this DAQ unit and properly reading measurements. I have 5 thermocouples connected to a hot plate, they are set correctly in instacal. The thermocouples are embedded at different depths of the plate to measure a gradient as the hotplate dries samples. These thermocouples are shielded except for the tip. The tip is in direct contact with the metal. When power is applied to ceramic cartridge heaters the thermocouple readings are bad...very bad. This isn't the first weird occurrence when using this DAQ unit. I have two other sensors that also read very wrong when they are in DIFFERENTIAL and not single ended. They measure fine in single ended (this is a setup for a different equipment set up, but mentioning it in case they're related). I have an older PDAQ-55 and I don't see any of these issues. It's stable and has amazing readings. This is an issue that we need to sort out as we plan on getting the extender for the 2416 and connecting a lot of sensors to it. And these need to be run in differential mode so we connect all of the sensors. It sounds like some sort of grounding issue. Any help would be greatly appreciated.
