Calibration Information

Because the M.O.L.E.® Thermal Profiler is made with precision components with high temperature stability and tight tolerances, the analog-to-digital converter remains stable for years. High quality components together with software algorithms based on the IPTS-90* standard for Type K thermocouples have been provided to yield the specified accuracy and long-term stability. Each unit has been tested at the factory before it is shipped.

ECD recommends the M.O.L.E.® Thermal Profiler is factory re-calibrated every 6 months when it is being used constantly. If the use is occasional, a period of no greater than 12 months between calibrations is recommended.

Good thermal quality programs require periodic calibration to show the Thermal Profiler continues to remain in calibration using a temperature standard. Any observed inaccuracies are probably not caused by calibration error but by any one of a number of other sources, primarily the following:

1.Poor thermocouple connections or open thermocouples.
2.Using a standard that is inaccurate or one not traceable to the National Institute of Standards and Technology.
Check the accuracy of your standard and that it is traceable to NIST. Be sure that you're using Type K special limits of error wire connected to the standard. Be sure that your standard is cold-junction compensated, or use an ice-point reference.
Make sure that IPTS-90 tables are being used.
3.Extremely low Power Pack charge.
Recharge the Power Pack. Refer to M.O.L.E.® MAP User Help System for details.
4.Sudden changes in ambient temperature.
Allow the M.O.L.E.® Thermal Profiler to stabilize for 1/2 hour before calibration.

If after checking these possible sources of inaccuracy and the M.O.L.E.® Thermal Profiler still needs to be calibrated, proceed as directed.

Do not attempt to calibrate the M.O.L.E. Profiler if you have never used a thermocouple simulator, or you are unsure of the accuracy of your Thermocouple Simulator. (Contact ECD for further assistance).
