1.01How the 3M™Clean‑Trace™ NGi Luminometer works to MeasureContamination
The 3M™Clean-Trace™ NGi Luminometer is a luminometer used in conjunction with 3M reagent kits to measure levels of contamination
on surfaces and in water samples. The technology used is Adenosine Triphosphate (ATP) bioluminescence. ATP is a substance present in all
animal and vegetable matter, including most food debris, bacteria, fungi and other micro-organisms. Measurement of ATP is performed using
an enzyme reaction which occurs naturally in the tail offireflies.
Luciferin/Luciferase (firefly reagent) + ATP =Light
The light emitted is in proportion to the amount of ATP. The intensity of the light emitted from a sample is measured by the
3M™Clean-Trace™ NGi Luminometer and is displayed in Relative Light Units(RLU).
1.02ATP and Surface HygieneTesting.
The 3M™Clean-Trace™ NGi Luminometer, together with the appropriate test kit, is an effective method for monitoring the hygiene status of
surfaces. ATP from both micro-organisms and product residues are detected. Measurement of “total ATP” provides an important insight to the
overall cleanliness. Product residues remaining on surfaces after cleaning will be a source of nutrients for any remaining micro-organisms
and may also protect the micro-organisms from disinfectant action. Because of the fast results, use of the 3M™Clean-Trace™ NGi
Luminometer allows immediate remedial action to be taken if an unacceptable result is obtained. Surfaces can be re-cleaned before use,
ensuring good sanitation and contaminationcontrol.
The test kit instructions should be read carefully beforeuse.
1.03ATP and WaterTesting.
Test kits are available for the assessment of contamination in liquid samples. Measurement of the total ATP in final rinse water samples is an
indicator of the effectiveness of Clean in Place (CIP) processes. The total ATP in process and waste water, water tanks and cooling towers can
be used to determine and monitor the efficiency of the biocide treatmentprogram.
Measurement of free or non microbial ATP can be performed in addition to total ATP for further information on the nature of
thecontamination.
The test kit instructions should be read carefully beforeuse.

2.02GeneralFeatures
The 3M™Clean-Trace™ NGi Luminometer is a light-weight, fully portable instrument with alphanumeric LCD display. The instrument is for
use in production areas, healthcare settings and laboratories and can be supplied with a carrying pouch. A separate internal Lithium Battery
is used to retain information in the instruments memory, with regard to sample plans, test points, data and calibrationsetting.
RS 232to PC is not functional on NGiLuminometer.
2.03Charging theBattery
The instrument runs on a removable, rechargeable Lithium Ion battery. The sealed battery pack is supplied with the 3M™Clean-Trace™ NGi
Luminometer and needs to be charged prior touse.
It is necessary to attach the battery pack to the instrument. Locate the battery pack into the aperture in the rear of the 3M™Clean-Trace™
NGi Luminometer by inserting the bottom of the battery pack first and pushing the battery into place. Secure the battery pack by turning the
fixing screw clockwise using a small screwdriver. Do notover‑tighten.
The 3M™Clean-Trace™ NGi Luminometer may now be charged using the charger supplied. Plug the connector from the charger into the
3M™Clean-Trace™ NGi Luminometer as shown in Figure 2, then connect the charger to an AC power outlet and switch on. Alternatively,
the optional docking station is used, insert the 3M™Clean-Trace™ NGi Luminometer into the docking station, plug the connector from the
charger into the docking station then connect the charger to an AC poweroutlet.
The battery in the 3M™Clean-Trace™ NGi Luminometer will charge fully in approximately 2hours and will then be ready for use. The
battery level indicator shows the state of charge. Remove the AC power and unplug the charger from the instrument. If a docking station is
used, the charger can remain attached to the docking station permanently. In this way, the instrument is always being charged ready for use
when it is in the dockingstation.
The 3M™Clean-Trace™ NGi Luminometer will display this screen when it is switched off
andcharging.

If the 3M™Clean-Trace™ NGi Luminometer is turned on and operating with the charger
connected, the arrow next to the battery symbol will beshown.
When switched on, the 3M™Clean-Trace™ NGi Luminometer will display a continuous indication of battery status at the top right of the
displayscreen.
The removable battery pack is held in place by a singlescrew.
To remove the battery pack, turn screw counter-clockwise untilloose
(it is a captive screw so will remain attached to the battery pack) then remove thebattery.
This shows the battery pack removed. Note the battery contacts. Do not touch or
contaminate them as this could lead to unreliable operation. The battery pack is only
available from 3M or localdistributor.
2.04Switching the InstrumentON
Ensure that no samples have been left in the chamber from previous tests before switching the instrument on. The power switch is the red
button on the instrument. Pressing and holding the On/Off button will switch the 3M™Clean-Trace™ NGi Luminometer on. Pressing and
holding the On/Off button again will switch the 3M™Clean-Trace™ NGi Luminometer off. When switching on, the 3M™Clean-Trace™
NGiLuminometer performs a series of self-checks, including an initial instrument background measurement and a calibration check.
Thefollowing screens will be displayed during initial start-up and system selfcheck.

2.07SwabSensor
It is recommended that as soon as the measurement of a test has been completed, the test device should be removed from the chamber
of the 3M™Clean-Trace™ NGi Luminometer. Should a 3M™Clean-Trace™ ATP test device be left in the chamber and the instrument
be inverted or laid on its side, there could be leakage of the contents of the test into the luminometer causing damage to the sensitive
components of theinstrument.
The 3M™Clean-Trace™ NGi Luminometer has a sensor to determine if a 3M™Clean-Trace™ ATP test device has been left in the chamber
for more than 30seconds following the completion of a measurement. If this situation is detected, the instrument will display a “Swab Left In
Chamber” error message on the screen and provide an audible beep to remind the user to remove the test following themeasurement.
Similarly, if a measurement is attempted in Program Mode without a 3M™ Clean-Trace™ ATP test in the chamber of the instrument, the test
sensor will notify the user that the chamber is empty with a “No Swab Detected” error message and an audible beep. This message will not
be displayed when tests are attempted in Measure Samplemode.
2.08Low PowerMode
If the 3M™Clean-Trace™ NGi Luminometer is switched on but left unattended for some
time during operation, the instrument will switch to Low Power Mode in order to conserve
battery power. During normal operation this will occur approximately 30seconds after the
backlight has switchedoff.
The Low Power Mode screen is displayed opposite. Low Power Mode can also be entered by
pressing and holding the top left green function button when in “MainMenu”display.
Pressing any green button (except red power button) on the 3M™Clean-Trace™ NGi
Luminometer will return the instrument to the screen displayed before the Low Power Mode
wasactivated.
2.09PCCommunications
In order to communicate between the 3M™Clean-Trace™ NGi Luminometer and
3M™Clean-Trace™ Online Software ensure that the luminometer is connected to the PC
via the USB cable or through the 3M™Clean-Trace™ Docking Station, which in turn is
connected to the PC via the USBcable.
The screen shown on the right is displayed when the PC is communicating with the
3M™Clean-Trace™ NGi Luminometer during the transfer of sample plans orresults.
