We start at the highest pressure and work downward for two reasons.
- It helps the fans reach the target pressures faster. The speed control algorithm works faster going from a higher pressure to a lower pressure.
- It helps you properly select your Range Ring for the test. By starting with the largest possible range (highest flow) to test at your highest pressure you ensure the minimum possible range changes while testing. Ideally, you don't want to change ranges in mid test because it wastes time.

You need to consider that there is a fundamental issue of uncertainty with using 4 Pa as a reference pressure. Just imagine, if there is even a 1 Pa fluctuation, due to so many possible sources that can cause pressure fluctuations as you know, the pressure measurement already has an uncertainty of +/- 25% error. Consider that for almost all airtightness testing standards across the world, the reference pressure for Flow results are either 50 Pa or 75 Pa.

Retrotec recommends you take the maximum number of test points to decrease the uncertainty in your test.
Yes, you can change this default and take only 5 readings according to the Standard but your uncertainty will often be too high and you might have to retest. Next, you might retest and find the result differs from the previous test by 10% or more making you lose confidence in the results. Retrotec defaults that include taking 10 test points and longer baselines will optimize your tests and give better results.
You might save a few minutes by testing to the minimum allowed by the Standards but in the long run, your test results will be poor. Officials look at high uncertainties and poor repeatabilities between your tests and wrongly conclude your equipment is faulty but the truth is that your test method is faulty. Please use our defaults as practical minimums and if anything take your tests over a longer time rather than shorter and your results will

This problem is often caused by anti-virus programs. In particular we have found that using Internet Explorer and a virus protection program from Microsoft called 'Windows Smartscreen'.
Disable your anti-virus program, uninstall the earlier version and download and install the new version from the website:

Uninstalling FanTestic will NOT remove any of your test files or reports, it will only uninstall the program files.
It is generally a good practice to regularly back your test and report data to a different location.
Uninstalling FanTestic will also NOT uninstall the DM-2 USB driver. You should still be able to see it listed as installed in your Control Panel after you restart the computer.

If you previously had to use the "ADMIN" shortcut to allow FanTestic to find your DM-2 then you need to make sure that the previous version of FanTestic and all shortcuts to it are removed from your computer.
Uninstall FanTestic completely from your computer using the Control Panel (choose the Remove from computer option, not the Revert to a previous version option if you are presented with a choice). Uninstalling FanTestic will NOT uninstall the DM-2 USB driver. You should still be able to see the Driver listed as installed in your Control Panel after you restart the computer.
Delete all FanTestic shortcuts on your desktop, including the one labeled ADMIN if it is present.
Restart your computer.
Install the latest version of FanTestic from the website.

In order to do both, you need to be sure you have version 5.8.30 of FanTestic or later.
In all versions of FanTestic before version 5.8.30, if you plugged a DM32 into a computer USB to give it power (instead of plugging into the wall adapter) FanTestic would assume you also wanted to use USB Serial connection for control. FanTestic made this assumption even if the gauge was also connected to the computer over Ethernet (via the Network cable or via WiFi).
In all versions starting with 5.8.30, FanTestic discovers gauges connected via Ethernet first, so it can ignore the same gauge also found on USB Serial.
This change allows users to have their DM32 connected for control via Ethernet but also connect the DM32 to the computer USB port for power (if it is more convenient than connecting to a wall outlet). Retrotec recommends that users use Ethernet connection rather than USB for controlling the DM32.
