April 13th 2017: Tcal Version 3.00 is Released
I hope you enjoy reading this blog post. My website has organised content about lots of different topics that are easily found from the homepage. This blog is a more informal area of my website.
I'm really excited to announce the publication of Tcal version 3.00. Version 2 was a robust, simplified way to produce a calibration certificate for a data logger. The same layout is retained. You simply follow the clear instructions in the spreadsheets that guide you through the whole process. There are two key improvements.
Firstly, version 3 adds new report pages describing the errors the instrument will produce. Practical information is presented for the non-technical and technical end-user. You can now easily add error bars to the results of any measurements you make. These report pages are all automated and in fact require no additional work by the operator compared to the previous version.
Secondly, version 3 also adds customised adjustments (offset and multipliers) for every channel/range combination. This is is a lot of information and you do not have to print it. The new print-management page will make deciding what to print and then printing it much easier.
These new adjustment figures help make sending an instrument away for adjustment by the manufacturer less important. Many instruments allow you to input adjustments in their user menus. Or, you may add these adjustments to your data processing. The difference in quality between a "calibration" and a "calibration with adjustment" (typically much more expensive) is now even more reduced with this version of Tcal. And remember that for many applications paying for an adjustment to reduce a 0.4% error down to a 0.1% error is unnecessary anyway: this extra detail in the calibration report can help add detail to an audit trail justifying your approach to error-tracking and management and potentially save you a lot of money and time.
The big-picture for many of the applications of data loggers is that you have to achieve a base-line quality and then do your best to go beyond that. (This might be a legal requirement or about being competitive against other businesses in your sector.) Tcal is now a very effective tool to achieve both of these things. Traditional calibration techniques often only help you achieve a base-line quality but do not help you push beyond it.
I believe that research and development time on Tcal is largely over now. I have one additional improvement that I am looking to release within the next year but otherwise my time efficiency working on Tcal is better than it was. I am passing this saving on. I estimate that existing customers will save approximately 10-15% on what I have previously charged. And for new customers the price is now even more competitive.
