7 Maintenance
7.1 Checking calibration
The factory calibration of the Reader can be checked. Calibration check
is recommended to be done as per Quality System of the user. Lifeassays
AB recommends monthly calibration check. Calibration check is
recommended to be conducted always when contamination of the device
is suspected or Reader does not meet user defined system suitability
test.
7.1.1 Manual calibration check
To check calibration manually,
1. Turn on the Reader.
2. Insert the ”Check Calibration” card in the Reader.
3. Insert the calibration cartridge.
4. Press the Measure button.
5. After the results are ready, record them.
6. Compare the results with the allowed values printed on the Calibration
cartridge.
7. Repeat the steps from 3-6 using second Calibration sample.
If the results do not match with the allowed values, clean the sensor
head as instructed in chapter Cleaning sensor head and carry out the
calibration check again from the beginning.
CAUTION
Do not inject any liquids into the standard
sample.
If the sensor heads is dirty, it may have
contaminated the standard samples for
calibration as well. Do not try to clean the
samples in any way.
NOTE
Store the standard samples in dry place in the
original package.
If there is any doubt of the functionality of the
standard samples, contact Lifeassays AB to order
more samples.
7.1.2 Cleaning sensor head
