| Abstract: |
Are Your Standards Enough? • Are you using a PRT or SPRT “standard” for your primary standard? What is the difference and why does it matter? • How do you know that your standard is in tolerance after returning from the vendor? • What to do when the data only states report on value. • How to check if your standard is in tolerance by drift of previous to current data. I will show you: • How some vendors calculate drift values. • Methods you can use to do a drift check. • Determine the best method - Triple Point of Water vs. Ice Bath. • Decide what equipment is needed to read your standard. • Choose between Ohm Meter vs. Resistance Bridge. Improving Quality Using RTD vs. Thermocouples • Learn what thermometer to use portable and bench top. • Understand portable issues with some thermometers IEC mode / ITS90 mode. • Learn how we came up with Coefficients off of multiple .385 tables. • Use a Data Acquisition Switch Unit for profiling chambers using custom made probes . How using a "Smart Connector" can increase your capabilities and improve quality. • Using Surface temperature probe, RTD’s, and thermistors. This “Back to Basics” paper was inspired by my search for an outside calibration lab to calibrate/verify my overflow items. Through my search, I found that three calibration labs didn’t check tolerance conditions of their primary standard although they did file the cert and data. One of the labs quoted me better uncertainty then NIST using a thermocouple and handheld thermometer We need to get back to the basics and this means starting with the primary standard. By educating smaller calibration labs how to verify their standards, we can rely on them for overflow/verification work. |
