Calibrating the Cardy isn't complicated. It's basically wash and rinse, wash and rinse.
To clean the sensor you can use distilled water, which is a lot less expensive than buying refills of the "de-ionized" water that comes with the kit. And don't use their testing tape to clean the sensor. Buy Kleenex brand facial tissues in those little pocket packs. They are potassium-free, and work just fine.
To calibrate the meter first:

Correlation of Saliva and Human Blood Serum Potassium Results
The Cardy results are reported in ppm (parts per million), so saliva results are calculated by multiplying the saliva potassium measurements on the Cardy Potassium Meter by 0.026 to convert the values from ppm to mmol/L.
The correlation results are based on normal human ranges for blood serum as 3.5 - 5.5 mmol/L and for saliva as 8 - 40 mmol/L. The saliva values, as measured by the Cardy K+ meter, have proven accurate when compared to serum values drawn and processed in labs.

It is now possible for the patient with periodic paralysis to test their potassium level at home, just as patients with diabetes test their glucose levels. The LAQUA potassium ion meter is not currently approved for medical use by the FDA, nor is it sold as a medical device, but it is the new and improved version of the Cardy C-131 Potassium Ion Meter, which was a very sensitive measuring device which has given excellent results to many patients in our group who have used it. Patients do not test their blood with these meters, but their saliva.
