According to the instructions, it seems that the sensor type has not been determined; in other words, there is an issue with the parameter settings. What do you usually do in such situations? Note: 5 points are added for each post.
If it does not affect the measurement, then simply eliminate it or confirm the alarm! It’s a bit like covering one’s ears while stealing! But sometimes, maintaining instruments is nothing but putting a bandage on a wound! ……If it has already affected the measurements, for this characterization setting, especially the K1 value, you should contact the manufacturer! ……Are the parameters indicated on the nameplate? Set them again! ……You can also try turning off the power and then turning it back on! ……
The problem now is that there’s nothing left except for one temperature!
You may still need to consult the manufacturer regarding the parameter settings; hopefully they can assist you online, or else you’ll have to send it back
