ATP Calibrator Set
GENERAL DESCRIPTION
The calibration devices in this kit are used for performance
verification and calibration of the LIGHTNING MVP ICON
™
and LIGHTNING MVP
®
systems. The luminescent calibrator
consists of a
14
C radioactive source that emits a very low level
(5 x 10
5
d.p.m., or 0.225 microcuries) of low energy ß radiation
in a plastic scintillation matrix. This matrix is configured to give
constant light output, within 10% of its original value, at a
sufficiently high level to make consistent verification and
calibration functions possible over the five-year life of the
calibrator. The non-luminescent black plastic calibrator provides
a reliable low-end or “dark” source reading.
Part No. 64012-00
KIT COMPONENTS
One luminescent calibrator
One non-luminescent calibrator
RECOMMENDED USE
A.
Performance Verification:
If a given test point result
or LIGHTNING MVP ICON ATP Positive Control result
is not what is expected, it is suggested that the calibrators
be used. You may wish to perform daily or weekly
performance verification checks consisting of simply
inserting and reading the calibrators. Calibrator results
should be compared with the Zone value stated on the
calibrator label and with previous calibration results.
If the calibrator results are within specifications (see
INTERPRETING RESULTS
), you can be confident
that the MVP ICON or MVP is functioning properly.
B.
Calibration:
The instrument’s Zone readings are
standardized by a two-point calibration procedure.
Note:
All MVP ICON and MVP instruments are factory
calibrated prior to being shipped. Because several factors can
cause the calibrator results to be out of specification, a full
calibration should be performed only if either of these two
conditions are true, and all of the conditions in “Causes of
Inconsistent Calibrator Readings” have been ruled out:
(a)
Luminescent calibrator readings are consistent within 0.1
Zones of each other but are not within 0.1 Zones of the
Zone value printed on the calibrator label.
(b)
Non-luminescent calibrator readings are consistent within
± 0.3 Zones of each other but are not within the 1.0 to
1.5 range. If, after cleaning and repeated tries, consistent
calibrator results cannot be obtained, call BioControl
Technical Support at 800.245.0113.
Note:
Accepting a particular calibration will set the sensitivity
for all subsequent readings. It is not possible to change a
calibrated instrument back to a former calibration.
STORAGE
Store at 15 – 25
˚
C in a tightly closed container, away from
any light sources.
MVP ICON TEST PROCEDURES
The calibrators are inserted and read in the MVP ICON and
MVP in the same manner as sampling devices. Unlike the
sampling devices, the calibrators do not require activation.
DO NOT ATTEMPT TO ACTIVATE THE LUMINESCENT
CALIBRATOR.
Hold the calibrator by the wider end with two flat sides and
insert the opposite end into the MVP ICON or MVP (an arrow
on the luminescent calibrator’s label indicates which end is to
be inserted into the instrument). When inserting into the MVP
ICON, ensure the flat sides of the calibrator’s base chamber
are facing left and right.
A.
MVP ICON Performance Verification
(a)
Select “Device” from the bottom menu and ensure the
MVP ICON is in ATP mode.
(b)
Select “Luminescent Cal” or “Non-Luminescent Cal”,
as appropriate, to run the verification.
(c)
Follow prompts.
B.
Calibrating the MVP ICON
(a)
Select “Device” from the bottom menu and ensure MVP
ICON is in ATP mode.
(b)
Select “Calibrate” and enter the reference value located
on the luminescent calibrator label.
(c)
Insert the luminescent calibrator and press “Calibrate.”
Repeat with the non-luminescent calibrator.
(d)
The MVP ICON will display “Calibration Successful” when
properly calibrated and will store the calibration in the
device. The last calibration date will appear on the
homescreen of the device. If the “Calibration Failed”
message appears, the calibration will need to be repeated.
If failed message still appears, contact BioControl
Technical Support at 800.245.0113.
LIGHTNING MVP TEST PROCEDURES
A.
LIGHTNING MVP Performance Verification
(a)
Open the sample chamber and insert the calibration
device. Close the sample chamber.
(b)
Select “Read ATP” from the main menu.
(c)
It is suggested that luminescent and non-luminescent
calibrator results be stored in the MVP memory for later
retrieval. Assigning these results test point numbers will
facilitate data collection and retrieval: for example, 996
non-luminescent, 997 luminescent.
(d)
Assign a test point number (if desired) and press the
“Enter” key to begin reading.
