Coding the Meter

IMPORTANT:
After setting the date and time for the first time, the current code will appear on the screen every time the meter is turned on. Verify that the code on the screen matches the code number on the package of test strips before each use of the meter. The code needs to be set only once for each package of test strips. The meter will memorise the code until it is changed. If the code number on the meter screen doesn’t match the code number on the test strip package, it will create an inaccurate blood lactate test result.

To code the meter with a code card, follow these steps.

Step 1: Locate the code card in the test strips package.
NOTE:
There is a code card packaged in each box of test strips. The code card is designed specifically for use with the test strips in that particular package. The code card should have the same code number indicated on the package of test strips.
Step 2: Verify that the code number on the code card matches the code number on the test strip package.
Step 3: Insert the code card with the code number facing up firmly and completely into the code card port on the back of the meter.
Step 4: Press any button to power on the meter.
Step 5: A 4-digit code number will display on the screen. Verify the code number on the screen matches with the code card number and the number on the test strip package.

NOTE:
Recoding needs to be performed when opening a new package of test strips with a different code number.

Checking the System
There are two ways to check performance of the L-Pet Veterinary Lactate Meter.
These checks are simple and very important to ensure accurate lactate readings.

The Monitor Checker confirms the meter is operating properly.
The control solutions confirm the meter and test strips are working together properly.

Monitor Checker Method:
It is recommended that the L-Pet Veterinary Lactate Meter is checked using this method when the meter is new and when the performance of the system needs to be confirmed.
To check the meter using a Monitor Checker, perform the following steps:

Step 1: Insert the monitor checker into the test strip holder (when the meter is either turned on or off), the L-Pet Veterinary Lactate Meter will now perform a series of self-tests.
Step 2: The meter display screen will show “OK” when self-testing is complete.
Remove the Monitor Checker from the test strip holder and the screen will then display “Ctrl”.
Step 3: Press “ENTER” to exit checking the meter.

NOTE:
If the screen displays “nt OK”, repeat the test. If “nt OK” continues to appear, contact the authorised dealer.

Control Solution Method:

The purpose of the control solution check is to validate the performance of the L-Pet Veterinary Lactate Meter using a standard solution with a known concentration of lactate. A control solution test that falls within the acceptable range indicates the user’s technique is appropriate and both the meter and the test strip are functioning properly.

When to perform a control solution test

When the meter is used for the first time
Whenever there is doubt that the meter or the test strips are not working properly
If the meter has been dropped, stored below -20°C or above 50°C (stored below -4°F or above 122°F) or stored in humidity levels above 85%
If the test strip bottle has been left open or has been exposed to temperatures below 4°C or above 30°C (below 39°F or above 86°F) and/or light or humidity levels above 85%
If the readings appear to be abnormally high or low

IMPORTANT:

The acceptable range for the control solution is listed on the test strip label.
Use only the L-Pet Lactate Control Solution and L-Pet Blood Lactate Test Strips.
Always check the expiration date for both the L-Pet Lactate Control Solution and the L-Pet Blood Lactate Test Strips. DO NOT use if expired.
If a control solution test result is not within the expected range that is printed on the test strip label, DO NOT use the system. Repeat the test until the result reports within the expected range. If the results continue to report outside the expected range, contact the authorised dealer.
Apply a drop of control solution to a clean, dry, non-absorbent surface and touch the reaction zone of the test strip to the drop.
DO NOT touch the test area with the tip of the control solution bottle.
DO NOT apply a second drop of control solution to the test strip.
DO NOT smear the control solution with the tip of the control solution bottle.
Please refer to the control solution package insert for additional information.

To perform a quality control test using the control solution, perform the following steps:

Step 1: Perform Monitor Checker method up to Step 2 (see P.16, Monitor Checker Method) and verify the code number on the screen is the same as the code number printed on the bottle.
Step 2: The screen will display “Ctrl”, and then insert an L-Pet Blood Lactate Test Strip.
Step 3: The screen will flash a symbol of a liquid drop. Squeeze a drop of control solution onto a clean, dry, non-absorbent surface. Do not apply control solution to the test strip directly from the bottle.
Step 4: Apply a drop of control solution to the yellow reaction zone in the middle top of the test strip.
Step 5: The screen will show timing bars “—-” that flash and then gradually diminish for countdown.
Step 6: After the timing bars disappear (approx. 45 seconds), the screen will show the test result. Compare the reading on the screen to the range indicated on the test strip label.
Step 7: Remove the test strip and discard it into clinical waste.
Step 8: The screen will display the blood test mode.
The test result of control solution will not be stored in memory.

NOTE:
If the test result is not within the expected range, repeat the test until the result reports within the range. If the results continue to report outside of the expected range, please contact the authorised dealer.
