As pure as possible.

The only alcohol to use with PATS is pure reagent grade isopropyl alcohol, NSN 6810-01-584-3650. That's the purest alcohol available. If you use the cheap kind, the PATS optical system will clog. The only fix is to send it to the repair facility in Alabama.

Take off the storage cap only to install the alcohol cartridge. That keeps dirt out of PATS that can cause contamination and bad readings.

Don't let the cartridge touch anything before you screw it into PATS. If you must set the cartridge down, set it upright on its end so it won't get dirty. While the cartridge is in the PATS, put the storage cap on the alcohol fill capsule to keep dirt out of the capsule.

Passing the Test

Before running a PATS test, make sure the tested Soldier doesn't eat, drink, use mouthwash or smoke for at least 30 minutes before testing. The Soldier should also wash off all colognes and lotions. Soldiers should avoid gum chewing and talking during testing. Failure to follow these instructions will ruin the tests.

After the Test

When you're through testing, remove the alcohol cartridge. Otherwise, alcohol saturates the counting mechanism. Put the storage cap back on to seal out dirt and moisture while the PATS sits. Let the PATS run for 3-5 minutes to get rid of excess alcohol.

Don't let moisture that's built up in the tube assembly during testing get in the PATS. When you take off the tubes, pull the tubes off without lifting them. Otherwise, moisture drains down the tubes. To dry the tubes, hang them up in the middle so both ends point down until the assembly is completely dry. Never use a tube assembly that's damp.
