Use it in this order.

Calibration order

Calibrate at pH 7.00 first, then pH 4.00. Pour each buffer into its own cup, rinse the electrode with distilled or deionized water between points, and never pour used buffer back into the bottle.

Storage

Keep pH and ORP electrodes in the 3M KCl solution between uses. Never store them in distilled or deionized water.
