Extruder Barrel Temperature Calibration

Hello Guys!

Need your expertise/advise here. Just want to know what is the correct way of
calibrating the extruder's barrel temperature, from zone 1 to 5.

Thanks in advance

Hello Mr. Lua,

First you need to purchase a portable, precision thermocouple type temperature monitor certified for accuracy by your government standards division or group and traced right back to the World SI standards. It should also have a sticker on it verifying same and showing when the next calibration date is due.

Then you go around to each extruder and, while hot, check the thermocouple output of each zone and other temperature indicators such as the melt temperature. The portable temperature monitor should fully agree with each temperature monitor or controller on the extruder. Then you place a calibration sticker on the face of each temperature controller or monitor on the extruder indicating that it has been calibrated, when and by who and also indicating that the calibration must be renewed say in one year's time.
