to open the File Explorer

window and navigate to the

CD drive that holds the install disk. Click on the

“AutoPlay” folder, then on the “Docs” folder and double-

click on the “setup.exe” file.

The “Welcome to the SASS 2300 Setup Wizard” screen

.NET Installation

If your computer does not have the .NET

Framework installed on it yet, instead of

seeing the Welcome dialog box you will be

prompted to upgrade your operating

system by installing the .NET Framework.

This is necessary for the SASS 2300

Windows program to run. This will require

an Internet connection and some time.

Unlike the SASS 2300 Windows program,

the .NET Framework can take several

minutes to install depending on the speed

of your system and requires up to 500 MB

of free hard disk space.

Calibration Table

The Calibration Table is used to convert raw counts from the optical

Calibration Table

The Calibration Table cannot be edited by the user in Normal

Calibration Table

The Scaling Factor at

the left bottom of the

screen determines the

milliliter values shown

in the right column in

the calibration table.

For a SASS 2300 this

value must always be

set to 7.0.

Changing the values in the calibration table can result in poor

sampling efficiency or flooding. Only an experienced technician

should attempt to re-calibrate a SASS 2300.

Sample Pump Timeout

The Sample Pump Timeout value can be viewed by selecting it

from the Options drop down menu on the main screen.

In Expert Mode the Sample Pump Timeout value can be set

from 0 to 255 seconds. This is the time that the sample pump

will run if turned on using the hardware switch on top of the unit

before automatically shutting off. This is done to avoid wearing

out the pump and running the battery down if the switch in

inadvertently bumped in transit.

If the pump is turned on using the Windows software program

this parameter will have no effect.

Run Cleaning Cycle

The SASS 2300 is capable of

running an automated cleaning

protocol that will rinse the system

out if it has become contaminated

for any reason. This can be

accomplished in one of two different

ways.

1. If the Sample Destination

switch is toggled three or more

times within three seconds it will

cause the automated cleaning

protocol to run.

2. The automated cleaning protocol

can be run by selecting Run

Cleaning Cycle from the

Utilities drop down menu which

will open up the screen shown.

Initial fill time is the number of

seconds that the pump should fill

the cyclone when the fan first

powers up.

Fan run time is the number of

seconds to run the fan.

the fan is shut off and the fluid is

pumped out the spigot port in the

back of the unit for the number of

seconds shown in the Pump run

The cycle of running the fan and

pump will be repeated until the

total number of cycles is equal to

the value in the Number of

At this point the cyclone will fill for

the number of seconds in the

This fluid is then pumped out of

the cyclone and used to flush the

Cleaning the Water Reservoir

The water reservoir should be cleaned

on a weekly basis to prevent the buildup

of bacterial biofilms when the unit is in use.

1. Open the reservoir and invert the

instrument to empty any water that

may be present.

2. Add a few mLs of household bleach

and recap the reservoir.

3. Shake the instrument with inversion to make sure the bleach

accesses all areas of the reservoir.

4. Open the reservoir, empty the bleach and add a few hundred

mLs of water.

5. Recap and repeat the shaking and inverting.

6. Empty the water and repeat this process 4 times to make sure

all the bleach is gone.
