EN (English) INTENDED USE

The 3M Clean‑Trace Luminometer is a battery operated Luminometer utilized primarily for objective and sensitive determination of the end result of Adenosine Tri-Phosphate (ATP) tests. The 3M Clean‑Trace Luminometer power supply is provided to charge the battery. The 3M™ Clean‑Trace™ Hygiene Management Software is designed for the transfer, organization, and storage of data generated from the 3M™ Clean-Trace™ ATP Tests. 3M has not designed nor documented the 3M Clean‑Trace Luminometer, and its power supply, or 3M Clean‑Trace Hygiene Management Software for use with other manufacturers’ products, use with other manufacturers’ designs, or use in any other application that has not been evaluated or documented by 3M and may lead to an unsafe condition. The 3M Clean‑Trace Luminometer is not intended to be used in potentially flammable or explosive environments. Although the 3M Clean‑Trace Hygiene Monitoring and Management System is very sensitive, surfaces or solutions should not be considered sterile based on results. The 3M Clean‑Trace Hygiene Monitoring and Management System is not intended to be used in the diagnosis of conditions in humans or animals.

PRODUCT DESCRIPTION Using ATP Detection for Hygiene Monitoring and Management The 3M Clean-Trace Hygiene Monitoring and Management System consists of the following: 3M Clean-Trace Luminometer, 3M™ Clean-Trace™ Tests, and 3M Clean-Trace Hygiene Management Software. This system is used to detect ATP on surfaces or in water samples to measure levels of contamination for the purpose of hygiene monitoring and management. The detection technology used is Adenosine Triphosphate (ATP) bioluminescence. ATP is present in all animal and vegetable material, including most food debris, living and dead bacteria, fungi and other microorganisms. The 3M Clean‑Trace Tests use Luciferin/Luciferase enzyme to produce light that is proportional to the amount of ATP present. The 3M Clean‑Trace Luminometer measures the intensity of the light emitted from a sample, and it displays the test result in Relative Light Units (RLU). Users do a validation study on their surface or water samples to determine the RLU test result pass, caution and fail thresholds. The rapid test results provided by the 3M Clean‑Trace Luminometer allow users to take immediate remedial action in response to a fail test result. The Test Point with a fail test result can be re-cleaned and retested before production, ensuring that hygiene management goals are achieved. The results provide data that can be used in part to make the decision to begin food or beverage production. Read the Instructions for Use documents for 3M Clean‑Trace Tests before using them along with a 3M Clean‑Trace Luminometer.

EN (English) OPERATING THE 3M CLEAN‑TRACE LUMINOMETER Battery usage and maintenance • A 3M Clean‑Trace Luminometer has an internal rechargeable lithium ion battery that must be charged to use a 3M Clean‑Trace Luminometer. Charging the battery • Select the charger adapter that is appropriate for power in your country. • Connect the charger to a 3M Clean‑Trace Luminometer. • Connect the charger to a power outlet. • The battery becomes fully charged in approximately 2 hours. • To monitor the charge status, turn on the 3M Clean‑Trace Luminometer. A lightning bolt icon appears in the battery charge level. When the battery is charged • Disconnect the charger from the power outlet. • Unplug the charger from the 3M Clean‑Trace Luminometer. Using the battery level indicator • The battery level indicator is located in the upper right corner of the screen. • When a 3M Clean‑Trace Luminometer is on, the indicator shows the remaining battery level. • In Figure 1, the indicator shows the battery is fully charged Figure 1 • As the battery charge decreases, the blue segment of the indicator becomes smaller. • When the battery level is less than 10%, the indicator becomes red, showing the battery should be recharged. • When the battery level is less than 5%, the 3M Clean‑Trace Luminometer automatically shuts down. Managing the battery • In normal usage, the battery provides up to eight hours of charge capacity. • As the battery ages, it will provide less than eight hours of charge capacity. • The battery must be charged when the indicator is red, indicating less than 10% charge capacity. • The battery does not need to be fully discharged before recharging. • When storing a 3M Clean‑Trace Luminometer for more than a month, the battery level should be at 50% charge. Do not store a 3M Clean‑Trace Luminometer with a fully discharged battery because the battery may lose the ability to be recharged. Do not store a 3M Clean‑Trace Luminometer with a fully charged battery because it may lose the ability to recharge to full power. • Battery replacement is recommended after two years of normal use. For battery replacement, the 3M Clean‑Trace Luminometer must be sent to a 3M Service Center. Switching the Power on Before switching on the 3M Clean‑Trace Luminometer, check the chamber to ensure it is empty. 1. Press and hold the gray on/off button located below the cursor control buttons. The red 3M logo appears to confirm the power on process has started, then the 3M logo Lockup appears and repeats several times. 2.

Use the Sync Manager software to initiate a synchronization between the 3M Clean‑Trace Luminometer and your computer. Refer to the Using the Sync Manager section of the 3M Clean‑Trace Hygiene Management Software User Manual for more information. • You must synchronize the first time using the USB connection. • A Diagnostic Check is automatically done when a synchronization is initiated. • If you start a synchronization less than two minutes after completing the last previous synchronization, a warning message appears. Wait at least two minutes, then start a synchronization again.

• If you synchronize a 3M Clean‑Trace Luminometer that already contains Sample Plans that are different than the Sample Plans on the computer you are currently synchronizing with, a warning message appears. o Tap Settings. Tap [Synchronize]. The progress bar shows when the synchronization is complete. o To cancel the synchronization, tap [Skip Sync] o To continue the synchronization, tap [Continue]. This option removes the Sample Plans and test results from the 3M Clean‑Trace Luminometer and replaces the Sample Plans with the Sample Plans on the computer with which you are currently synchronizing. • Synchronizing the 3M Clean‑Trace Luminometer with the computer sends information in both directions: Sent from Computer to 3M Clean‑Trace Luminometer: - User names and PINs - Sample Plans and Test Points including pass/fail limits and images of the Test Points if available - Organization configurations such as number of days to retain synchronized test results Sent from 3M Clean‑Trace Luminometer to Computer: - Test Results including date and time of test, User who did the test and comments if available - The 3M Clean‑Trace Luminometer provides three modes of communication: USB cable, Wi-Fi connection and Bluetooth connection Setting Up Synchronization with a USB Connection To use a USB cable connection: connect one end of the 3M provided USB cable to the USB/Power port and connect the other end of the USB cable to a USB port on your computer. • To register a 3M Clean‑Trace Luminometer the first time you synchronize it, log in to the Sync Manager.
