This Quick Start Guide is designed to expedite the basic setup and
powering up of the MITA. Upon completion of the following steps the MITA
will be ready to proceed with the Self Check or Test Masks functions. Refer
to the Operators Manual for additional and more detailed information.

The TSI Mask Integrity Test Accessory (MITA) works in tandem with the
PortaCount® Respirator Fit Tester to test for leaks or other defects in
CBRN gas masks and full-face respirators.

The MITA has been designed for ease-of-use and ease-of-transport. The
top half of the carrying case holds the instrument while the bottom half
forms the accessory compartment.

The display on the MITA guides the first time operator through step-by-step
prompts. The display also provides detailed guidance to how to use the
various accessories.

The following acronyms are used in the MITA menu structure and in this
Quick Start Guide.

Quick Start Guide 9

Set up the PortaCount® Respirator Fit Tester

Note

The following examples pictured will use the 8030 and 8038 models of
the PortaCount Respirator Fit Tester.

If you are using the 8030 or 8038 model of PortaCount you must have
version 2.6 or greater firmware installed to communicate with the MITA.

1. Connect the USB-to-Serial Converter to DB9 connection of PortaCount
interface cable.

2. Plug the USB end of the USB-to-Serial Converter to either type A USB
port located on back of PortaCount unit.

3. Connect the power supply barrel connector from the PortaCount
interface cable to the power supply connection on the back of
PortaCount unit.

4. Connect the end of the Twin Tube sample tubing provided with the
MITA, which is evenly cut to the color-coded fittings on the PortaCount
Fit Tester.

Sample port

shake it to allow excess alcohol to drip back into the Capsule. Refer to
the PortaCount user’s manual for more information on how to properly
charge the alcohol cartridge prior to use.

6. Insert the Alcohol Cartridge into the cartridge cavity of the PortaCount
Respirator Fit Tester. It should slide in with little effort. DO NOT
FORCE IT. When almost fully inserted, firmly twist the Alcohol
Cartridge clockwise until it locks into position.

7. Perform a PortaCount Daily Check every day as described in the
PortaCount Fit Tester User’s Manual before using with MITA.

8. At the other end of the Twin Tube sample tubing, the clear hose is
approximately 1 inch longer than the blue hose. AFTER performing a
PortaCount daily check, connect the clear hose to the mask sample
port at the bottom of the Headform.

9. If using the 8030 or 8038 models of PortaCount, they must remain on

the “Activities” screen. Trying to use the 8030 or 8038 on any other
screen will cause intermittent “unexpected response” errors on MITA.

Quick Start Guide 11

Prepare Masks for Test

Note

If you have not already performed a Self Check for the day, please
complete this process BEFORE testing a mask.

WAIT to install the Mask on the Headform until the Mask Protection
Factor test prompts to install it. The mask is installed ON the Headform
ONLY during the Mask Protection Factor test.

If the mask being tested has a Drink Tube or Exhalation Valve that will
be tested, leave the mask OFF the Headform. Both Drink Tube Test and
Exhalation Valve Test are done with the mask OFF the Headform.

Note

Typically masks seal better to the Headform bladder when placed
slightly higher up on the headform, so that the upper sealing surface is
less than an inch below the top of the headform bladder. This is not
applicable to all models and sizes of masks, and experience will help to
determine which masks fit best which way. Try adjusting the mask
higher or lower on the headform first when experiencing difficulties
passing a Protection Factor test.

This menu option provides information on how to prepare the gas masks
and full face respirators for testing. The Mask Test Protocol is selected and
defined in the Settings Menu.

1. Before starting, thoroughly inspect the mask to detect any obvious
defects.

2. If the inside of the mask is dirty or contaminated, it should be cleaned.

3. Remove the mask filter before conducting the Mask Protection Factor
test.

4. Install the appropriate Mask Filter Plug in place of the mask filter
removed in the previous step.

When installing the Mask to the Headform:

1. Loosen the mask straps completely so they will go around the back of
the Headform

2. Locate the chin cup of the mask on the chin portion of Headform first,
and pull the mask straps up and back over the Headform, making sure
to keep it snug to the Headform.

3. Make sure the Mask is centered on the Headform Bladder Seal.

4. Snug the straps tight.

5. Re-check to make sure the mask is centered from side to side.
