3. pH Calibration
3.1 Calibration Procedure
1.
Switch the
pH Cube
to pH mode (see section 2).
2.
Plug the pH sensor into the
Sensor
socket and the temperature sensor into
the
Temp
socket.
3.
Ensure that temperature has already been calibrated or manually set (see
sections 5.1 and 5.3).
4.
Remove the wetting cap from the pH sensor.
5.
Rinse the pH and Temperature sensors in distilled water and blot them dry.
6.
Place both sensors into a small sample of primary buffer that is at or near
pH7 (eg. pH6.88 or pH7.00). The bulb and reference junction should both be
covered, as per the diagram below.
DO NOT
place the sensors directly into the buffer bottle.
