Validation procedure:
Make sure the rotary switch on the sensor is
set to position “M” and that the pH buffer and sensor has the same
temperature. Open a bag of pH buffer 7. Place the sensor into the pH
buffer. Stir the sensor electrode tip around in the bag and wait a few
seconds for a stable reading. Make sure there is enough pH buffer to
cover the tip of the sensor electrode. Enter “7” in pH field above the
“Start Validation” button, and press the “Start Validation” button.
