... this is the essential point to bear in mind when comparing the Datrend approach with others (especially Ansur). It's a practical (real world) consideration.

In short, vPad (Datrend) uses Android tablets to "drive the device" (test equipment), with "apps" to be installed depending upon which test equipment in being used (and which, if any, CMMS is to be linked to). In fact, you could say that the tablet is part of the test equipment (a situation that becomes obvious when you glance at the latest Datrend test equipment).

Whereas Ansur needs (uses) a "plug-in" (dedicated software) for each item of test equipment (electrical safety tester, NIBP tester etc.), vPad uses an "app".

I believe there is merit in both approaches. For instance, I like the "drag and drop" style of the Ansur template building "screen" - it's (what they call) "intuitive" (and has been that way from the very first Metron versions).

From the little I've seen so far of OneQA, it seems to be very PC - or large laptop - centric, and what we might call "document based".

Yes; wise words.

This is an interesting one, Peter; have you had any joy with it yet?

My first guess would be a "bad" connection at the endoscope (front panel). Do you have more than one endoscope to try (swap over)?

Re: Testing of therapeutic ultrasound Geoff Hannis 09/05/21 6:52 PM
Where budgets allowed, the instrument of choice used to be either the Bio-tek UW-3 (see image below) or the Ohmic UPM-DT 100AV. Similar test kit was available from others (BC Biomed USP-100SP, Fluke UW-5, Netech UPM-2000 et al ... all working on the same principle).

This .pdf gives an idea about the current Ohmic range (as does this link).

Failing that, if money is tight, and you only have just one or two units to check out, you could (do as we once did and ...) make your own "ultrasound output indicator" out of a glass jar (we found a square one - some sort of tank) and fashion a "deflection vane" dangling on a wire frame. The vane to be under degassed water, of course. Trial and error is then required before marking output levels on the glass, as pointed to by the er, pointer. If I remember rightly, we were looking for Watts per square centimetre.

When it comes to frequency, I should imagine that waving a probe (or wire hook) from a frequency counter in front of the transducer should do the trick. We're usually looking for 1 and (or) 3 MHz. Remember not to run the unit for too long without a load (that is, bung some coupling gel on the transducer surface).

Meanwhile, here is an "learned article".
