Your Input on Advances in Diagnostic Testing Equipment

On May 11, 2016, Bill Spohn will be presenting to his local RSES group on the topic of “Understanding the Features and Limits of Your Diagnostic Testing Equipment” – a synopsis of the session is below.
Bill is looking for your input and opinions on the following statement:
“Lots of people are raving how they increase their productivity.”
Are you pro or con? Or could care less?
drop Bill an email and let him know what you think!

SYNOPSIS
“Understanding the Features and Limits of Your Diagnostic Testing Equipment”
Technology keeps on advancing and with it the technology that is in your tool kit.
Bill Spohn, President and Owner of TruTech Tools, LTD (and formerly with Bacharach and Testo for 10 years each) will give an overview of the changes in diagnostic test equipment technology that he has seen in the last 25 years.
Most notably we will discus the acceleration towards new wireless and smart device based products.
Lots of people are raving how they increase their productivity. Bill will share his opinion and some data on this.

  1. The prevalence of “digital manifolds” these days is making the process of measuring superheat and subcool easier than ever, which makes it more likely that these critical measurements will actually be taken. The ability to document measurements as taken on the instrument and share through email instantly is fantastic as well. One advantage of these features is that it is now possible for less experienced techs to take measurements and then share the readings with more experienced a more knowledgeable person for interpretation. In my opinion, this can help productivity in the short term, but may have a negative effect as junior techs may be less able to get the learning and understanding for themselves and never develop good diagnostic skills.

    When it comes to wireless meters and test instruments, these products help improve safety by allowing the technician to keep important personal items such as fingers, hands, and eyes away from the source of energy when taking electrical, pressure, or temperature measurements. They can also allow techs to “be in two places at once”. The extra advantage of something like monitoring compressor amp draw on one unit while you change filters on other units is a great time saving advantage.

    However, test instruments that send readings exclusively to a mobile device and do not have their own display have a built in weak point: Cell phones and tablets do not have the same durability as most test instruments. Every cell phone disaster I have ever had happened at work. Wireless instrument users must have reliable backups!

    One final note about digital refrigerant gauges: A digital gauge converts a pressure input into an electrical signal that then goes to a computer for analysis. The computer’s program interprets the signal and then makes a ‘decision’ about what to display on the screen. There are quite a few links in that chain!

    By contrast, a bourdon tube type gauge is directly connected to the pressure source. Any fluctuation in pressure will be directly indicated by the needle with no interpretation or possibility for confusion. Plus, no batteries!

    Once again, digital manifold users should also have good analog backups!
