Test setup time

Test setup is arguably one of the most important and critical steps of your testing procedure. If a test is set up and prepared for correctly, you can minimize your uncertainty in data, reduce your test time, and be able to conduct repeatable, traceable measurements.

Test preparation includes setting the DUT to the units, gas type, correction mode and modes speci­fied within the manufacturer’s service manual. The analyzer must then be set up to match these set­tings, or face manual calculations, and can include: units, gas type, correction mode, flow-testing (bidi­rectional vs unidirectional), setting the threshold or trigger point, in addition to other settings.

In many analyzers on the market, you must set up the analyzer and every detail before each and every test, regardless if it is the same test on the same model of DUT. It may be easily done, or not, requiring searching through menu after menu. Regardless, as biomedical and service engineers, you know that saving even just 5 to 10 minutes on every test, adds up in the long run to huge pro­ductivity savings.

With the VT650 and VT900A Gas Flow Analyzers, you can prepare a test setup only once, and then save it as a profile. The analyzers can save up to 20 unique profiles.

What is a profile?

In the VT650 and VT900A, a profile is a customized configuration of the analyzer. Anything set up in the analyzer, from units, customized screens, cor­rection mode, etc., can then be saved as a profile. A profile can be created for every model of DUT you’re testing, type of testing, or user preference.

How do I create a Profile?

Creating a testing profile on the VT650 and VT900A is fast and easy:

Pro tip:

You can rename the profile to something that resonates with you— for example, the model name of a ventilator in your facility; or type of testing. This is highly recommended.

Pro tip:

If you are using one profile more frequently than the others, you can select “ Use this profile on power-up”. The VT650 and VT900A will automatically load that profile upon power-up, eliminating analyzer setup time and reducing your total test time.

Your profile will be shown on the left side of the title bar, so you always know what profile you’re on, helping reduce human error.

How to edit a profile

If you have a profile created, it is easy to update. To make your desired changes to the setup and con­figuration of the analyzer, go to “Profiles”, be sure the profile you want to highlight is updated, and click “SAVE.”

How to view details of a profile and load a profile

From the “Profile” screen, you will see a list of all the profiles saved on your analyzer. The first option, “00: FACTORY PROFILE” will always remain at the top and unchanged.

  1. To see the profile you are currently using and what its configuration is, press “View Current”.
  2. If you are deciding which of your profiles you want to use, highlight a profile and press “View Selection” to see that profile’s configuration to determine if it’s the one you want.
  3. To load a profile, simply use the arrows to high­light the profile you would like, and press “Load”.
  4. You cannot delete a profile, but you can change the name. Highlight the profile you want to change the name of using the arrows, and press “Edit Name”.

How much time can I save with profiles in the VT650 and VT900A?

And this is just the time saved from your test setup.
