Frequently Asked Questions

What is the difference between operating software, test files, and the PC App?

All three types of programming are necessary for the proper use of a TTi® Colorimeter. The operating software, or “firmware,” is already installed. This code provides the basic functionality of your meter. In the event the firmware is updated at some point in the future, you will be notified through the PC App and you can install the update at no further cost to you. Test files contain specific instructions to run water analyses; the analytes that can be determined, and their ranges, depend upon the TTi model you purchased. When new tests are released for your model you will be notified through the PC App, and at your option you can install the files on your meter for free. (For the most current list of tests that can be performed with your model, go to “Helpful Links/See test chemistries” in the dropdown menu under the Support button, above.) You are given access to the TTi Colorimeter Series PC App when you register as the owner of record. A one-time installation allows you to:

  • Read the latest edition of the TTi Colorimeter Series User’s Manual online, download it to your computer, or print it out for your files
  • Transfer test results from your meter to the customer database you maintain on your PC or laptop
  • Create proprietary (i.e., user-developed) test files
  • Keep the meter’s operating software (i.e., firmware) up to date
  • Receive notification of newly available test files, as well as any improvements to existing test files, so you can add them to your meter’s capabilities
  • Keep the PC App itself up to date

What are the minimum system requirements for use of the TTi Colorimeter Series PC App?

The minimum system requirements are as follows:

  • CPU: Pentium® III or better
  • RAM: 500 megabytes
  • Available Hard Disk Storage: 30 megabytes
  • Operating System: Windows® XP, Windows® Vista, or Windows® 7 (compatible with 32-bit and 64-bit systems)

I don't see tests for some of the treatment products we sell/use among the meter’s preprogrammed tests. Can I add these tests myself?

Yes, you can create as many as eight user-developed test files. Once you have installed the PC App, you have access to the TTi Colorimeter Series User’s Manual which contains complete instructions for creating your proprietary tests.
