In this blog post, I want to share with you a two-part webinar series titled “How to calibrate pressure instruments” we did together with our partner ISA (International Society of Automation).

In this blog post, I will discuss the most common data integrity pitfalls in the calibration process.

Whether the calibration process is fully paper-based, or partially utilizing documenting calibrators, or even fully paperless, there are places in calibration processes where data integrity most commonly is jeopardized and needs special attention.

How often should instruments be calibrated? That is a question we get asked often. It would be nice to give a simple answer to that question, but unfortunately, that is not possible. Instead, there are several considerations that affect the answer of a correct calibration period. In this post, I will discuss these considerations.

In this post, I would like to talk you about the Ohm’s law. Why? Because it is helpful in many practical every-day situations, especially if you are an instrument technician. We often get questions that can be answered with an answer derived from the Ohm’s law.

This post includes the recordings of the two-part webinar series titled “How to avoid the most common mistakes in field calibration” we recently did together with our partner ISA (International Society of Automation).

This post discusses calibration in hazardous area in the process industry. 

In this blog post, I will take a short look on thermocouples and especially on the cold junction and the different cold junction compensation methods.

In this blog post, I explain how a resistance or RTD meter works and the difference between the 2, 3, and 4 wire connections.

We regularly get asked, “what is barometric pressure?” So I decided to make a short blog post to answer this. 

If I had to summarize the content of this post into one sentence, it would be:

Using a mA meter with an internal impedance that is too high to measure current over the transmitter’s test connection will result in erroneous measurement results!
