Welcome The QuantiFit2® can be used standalone or with OHD Logic software. When testing without a computer, all reports and test data may be retrieved from the instrument. Data can be imported into Logic software. The instrument is not compatible with FitTrack Gold, which comes with the legacy Quantifit. - Page 4 Before and after fit test steps, when the test subject is wearing a respirator, his or her inhalation is coming through inlets in the OHD adapter kit, and most of the exhalation should travel through the exhalation valve and out of the respirator. There are many potential respirator and adapter configurations.

Page 5: How The Quantifit2 Works
How the QuantiFit2 Works The QuantiFit2 functions by creating and maintaining a negative pressure in the respirator. Once the adapter valve is closed, sealing the respirator, the QuantiFit2 removes air from the respirator until the challenge pressure is reached. When the challenge pressure is reached, if there isn’t a leak, the QuantiFit2 doesn’t remove any more air from the respirator. -

This includes running tests, adding people, adding respirators, viewing test statistics, and identifying those people who are due for testing. Each of the modules seen on the Home Page can be collapsed by clicking on the no- view icon. - Page 29 Home Screen Test Creator To perform a fit test, it must be launched from the Test Creator. The Test Creator is a simple guide to record pertinent test information and to initiate the test.

People The people list shows the people in the currently selected company who have not been made inactive. The All Companies box can be checked for a list of people throughout all companies. Users can be made inactive if they have left their position, or no longer require fit testing. Their records will not be deleted, but they will be hidden from view. -
Page 33: Company
Company Many QuantiFit2 users will have only one company, while others might have dozens, depending on the needs for testing. The purpose for a Company is to create a division within the database. The company name will appear on the top of the fit test reports. Company divisions are not necessary and are only for convenience. -
Page 34: Tests
The test screen is where any active test can be viewed. This may be one test, or it may be for an operator who is controlling multiple instruments. The QuantiFit2 allows users to run countless machines simultaneously through the OHD Logic software (as many machines as an operator is capable of overseeing), with flexibility on the start time for any test. - Page 35 Tests The testing sequence When initiating a test from Logic, the software will display the inhalation valve message reminder, and then display the tube connection instructions. These two screens can be turned off by checking the box next to "Hide these messages next time." The test subject will view a message that says, "Device is in remote mode.
