HOW OFTEN SHOULD YOU CALIBRATE?

Plants can improve their efficiency and reduce costs by performing calibration history trend analysis. By doing it, a plant is able to define which instruments can be calibrated less frequently and which should be calibrated more frequently. Calibration history trend analysis is only possible with calibration software that provides this functionality. Download this whitepaper to learn how to use calibration history trend analysis to adjust calibration intervals of plant instrumentation. The whitepaper is free, but registration is required.

IMPROVE LOOP CALIBRATIONS
Significant performance improvement can realized by optimizing the loop calibration measurement system to better accommodate the unique characteristics of the temperature sensing element. This four-page PDF walks you through the necessary steps to get the most from your temperature sensing equipment. The direct link is at  http://tinyurl.com/k4lv7f6.

MAINTAINING YOUR pH SENSORS
All pH readings are supposed to be taken and accepted only when the pH sensor is clean, so one must make sure the sensor is clean before doing a calibration. Once a pH sensor is installed in the process and operating, how do you determine when it is time to take the sensor out of the process, and do a cleaning or calibration? Does one perform both a cleaning and a calibration or just a cleaning, or just a calibration? This paper will address knowing when to do a pH sensor calibration versus a calibration check; how to properly clean a pH sensor; how to perform a pH sensor calibration; and a decision tree for step-by-step guidance.

CALIBRATING SMART INSTRUMENTS
In the early days of smart transmitters, the concept of remote range setting ("remote calibration”) and re-ranging without applying input was revolutionary. It took years of education to be accepted and understood. Calibration can be carried out using a handheld communicator in the field, a laptop in the workshop, or from intelligent device management software as part of an asset management solution. Electronic Device Description Language (EDDL) is the technology used by device manufacturers to define how the system shall display the device information and functions to the technician. This document  covers how EDDL works with sensor trim, range setting, position feedback sensor trim, device integration and other issues.

CALIBRATION TUTORIAL
This free tutorial covers calibration basics: instrument system models, instrument errors, range, accuracy, repeatability, stability, time-lag error, reliability, drift, proper procedures and calibration errors. Each section contains diagrams, basic equations and self-assessment tests. On completion of this tutorial, you should be able to explain the model of a basic instrument system, calculate the relationship between input and output for a complete system, explain and identify the main errors that occur in instrument systems, explain the basic principles of calibration, and explain primary and secondary standards. The link to the tutorial is www.freestudy.co.uk/instrumentation/tutorial4.pdf.
