I am encountering inconsistencies when collecting data sets with thermocouples.
I am using Omega K-type thermocouples, and allowing the 45 minute warm up, with DAQami to collect.
I have bundled the thermocouples together (without contact) with another datalogger's thermocouples(onset HOBO 4-channel thermocouple datalogger - this matches our EXTECH INSTRUMENTS EasyView 10 sensor). This was suspended in a sealed metal box with a heat lamp facing it (the temp increases)
This is an image of the temperature plotted over time. These datasets were collected at the same time in the same place.
The temperature over time of the USB-2416 is not accurate. Even after switching the thermocouple types between the two loggers (the different types were accounted for in the software), the USB-2416 will fluctuate and not be correct.
Any suggestions on how to troubleshoot or correct this issue?

Hello,
I have a datalogger (USB-2416 SN: 107817) that was recently checked for calibration by a third party (cirtificate attached).
