Is it the correct type of thermocouple? If it is designed for a K type and you put a J or T the reading will be lower. Also a bad connection can give a lower reading.

Thank you all. It was a bad connection. Everything is running fine. Happy new year to everyone! Emil

We use SMD glue to fix our thermocouples to the PCB, pretty destructive method (although boards will stil work), but there is nothing worse then making a measurement, waiting for everything to cool down, to then find an bad thermocouple connection wh

Wow, 15 degrees C is too much. Is this a new problem or new oven? If it's a new problem several things you can check out. Thermocouple placement may have got knocked into the wrong spot, or it could be dirty. I've seen this happen after a PM and

Can you please contact me? We may have work for you related to Conceptronics HVA102 oven. Our oven is not showing any readings from thermocouples. We suspect bad special function card? My number is 774-553-6644, ask for Greg.

We never really use to calibrate the thermocouples on our reflow oven or wave solder systems, but we did disconnect the T/C's and input a calibration standard to check that the computer cards were correctly reading the proper temperature for a given

Hi all, I will be looking into ovens shortly for our conversion to lead free. I hear and understand why our Heller 1088 oven wont make the cut for lead free (4 zones isnt enough). Can anyone recommend a good mid range oven? We have been very happy

Good day all, we have a Heller Reflow oven here that has been in service for about 2 1/2 years now. Aside from 2 thermocouples going bad it hasn't had any problems. My question is, how often should it be serviced for preventative maint. and does an

I have seen bad transistors on the expansion boards cause no display of temperatures from the thermocouples. Jerry

Typical problems with our heller 1707 EXL would be blower issues. We have almost replaced every blower on the top sense purchase. Fortunately Heller is very good about honoring there warranty on the blowers which is quite long, Might be lifetime not
