How do I calibrate the meter for β-Ketone testing?

You must calibrate the meter each time you begin a new vial of β-Ketone test strips by inserting the code strip while the meter is off and waiting for the code number to appear on the display. Ensure the code number on the display matches the number on your individual foil packet, then remove the code strip — the display will show 'OK' to confirm coding is complete. If the codes do not match, repeat the calibration procedure, and if the problem persists contact GlucoRx Customer care on 01483 755133. (Page 15)
