Why Thermal Profiler Calibration Is Important and When

Posted on Jul 26, 2010

Calibration of electronic measurement instruments is a necessary process, even though most electronic equipment is very stable and somewhat “resistant” to the effects of environment and changes due to aging.

Q: So why calibrate if my MOLE is "in spec" every time I send it in for calibration?

Because calibration is not so much an adjustment process but rather a proofing process that shows, over time, that your MOLE has been in calibration and thus should remain in calibration, because you have a track record to prove it. Documented history of a MOLE’s performance is the only way to claim your MOLE is in calibration at any given instant.

Most good labs will tell you that when your MOLE is calibrated, it is compared to standards , typically standards that have traceability to NIST, and if it is shown to be measuring within its specified accuracy they will not make any attempt to "adjust" it. Only if it is "on the edge," which usually means it is getting to the last 10% to 20% of the specified accuracy limit, will they make any adjustments. Your MOLE may still be "in spec" and thus "in calibration," when the lab received it, but getting close, so they will adjust it closer to the middle of the spec. range.

If it is out-of-spec when received by the lab, then a red flag goes up and calls into question every measurement made since the last calibration! The lab will tell you how far out of spec it is, and you can decide if its measurements during that time affect the quality of the measurements made more than can be tolerated, or if they are "close enough" to still be acceptable.

Q: So, when should the MOLE be calibrated?

The number one best time to calibrate the MOLE is on a regular time-based interval, which is recommended once a year. However, there are other events which may cause you to want to seek calibration at other times of the year, such as:

  1. When the MOLE is subjected to rough treatment like a fall to the floor,
  2. When your MOLE is accidently "over heated",
  3. When you are starting a new product introduction and you are characterizing an oven and new assembly to find the right recipe,
  4. When a new customer's contract stipulates you use equipment that has been recently calibrated,
  5. When your in-house quality program requires a calibration interval.

Getting your MOLE calibrated is easy and we want to make sure you are always making the highest quality temperature measurements.
