Because the SuperM.O.L.E.™ Gold 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-68* standard for Type K thermocouples have been provided to yield 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. 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 connectors or open thermocouples. |
| 2) | Using a temperature standard that is inaccurate or is not traceable to the National Institute of Standards and Technology (NIST, formerly the Nation Bureau of Standards). |
•Check the accuracy of your temperature standard and that it is traceable to NIST. Be sure that you’re using Type K wire connected to the standard. Be sure that your temperature standard is cold-junction compensated, or use an ice point reference.
| 3) | Extremely low Power Pack charge. |
•Recharge the Power Pack. Refer to topic Charging the Power Pack Battery.
| 4) | Sudden changes or excessive ambient temperatures. |
•Allow M.O.L.E. Profiler temperature to stabilize for 1/2 hour before calibration.
If after checking these possible sources of inaccuracy the M.O.L.E. Profiler still needs to be calibrated, there are two calibration methods: Using a thermocouple simulator and another using a voltage reference and an ice point.
|
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 the proper calibration procedure P/N A31-0900-05). |
If you need to return the M.O.L.E. Profiler for re-calibration, contact ECD and request an RMA (Return Materials Authorization). Refer to the Service and Troubleshooting>How to Get Additional Help topic for your M.O.L.E. Profiler for contact information.
