VI. Calibration
The Myron L
®
 Company recommends calibrating twice a monthdepending on usage.
However, you should check the calibration whenever measurements are not as
expected.3-pointWetCalibrationismostaccurateandisrecommended.
NOTE:IfthemeasurementisNOTwithincalibrationlimits,“Error. Clean sensor. Check
Solution.”willdisplay.ChecktomakesureyouareusingaproperpHbuffersolution.If
thesolutioniscorrect,cleantheglassbulbofthesensorwithacottonswabsoakedin
isopropylalcohol.Restartcalibration.
NOTE:Smallbubblestrappedinthesensormaygiveafalsecalibration.
NOTE: If at any point during calibration, you do not submerge the sensor in solution
beforetheashingslows,allowthepentopoweroffandstartover.
A. Calibration Preparation
1. Formaximumaccuracy,fill2cleancontainerswitheachpHbufferyouwillbeusing.
Arrangetheminsuchawaythatyoucanclearlyrememberwhichistherinsesolution
and which is the calibration buffer. Always rinse the pH sensor between buffer
solutions.
2. EnsurethepHsensoriscleanandfreeofdebris.
NOTE:Ifyoudonothaveenoughbuffer,youcanuse1containerofeachbufferfor
calibrationand1containerofcleanwaterforallrinsing.
B. Multi-Point Calibration (2 and 3 point Calibration).
Toperformamulti-PointCalibrationyoumustalwaysstartwith7.0pHbuffer.
1. TaptheCALbuttonintheFeatureNavigationBar.
TheAppscreenwillappearandsay,“Paired ULTRAPEN is Ofine”.
2. Graspthepennearthebatterytoavoidsamplecontamination.
3. Removepenfromtherinsesolution.
4. Pressandreleasethepen’spushbutton.TheCalibrationscreenwilldisplay,“Press
and hold the button on the ULTRAPEN to enter CAL mode.”
5. PressandHoldthepen’sbutton.TheLEDwillgotosolidONandtheApp’sCalibration
screenwillappear
6. TapthegreenCALbuttonontheCalibrationscreen.
