Calibration
The probe must be calibrated in the following cases:
•
Initial use
•
After changing the electrolyte
•
After changing the probe head
•
Whenever a precise measurement is required
Operation Mode:
Notes:
Ideally, the calibration should be performed at a temperature
approximating that of the experiment planned and in a moderately
humid atmosphere (50 to 70% RH). In practice, the ambient
conditions of a laboratory or classroom are sufficient for a
satisfactory calibration.
It should be noted that the level of CO
or so students can increase by 0.3% by the end of the period. It is
therefore best to perform the calibration in a well-ventilated room.
4.1 With your Primo/VTT or Visio interface
4.1.1 Connect the probe to the adapter and the adapter to
the ESAO console.
The adapter must be plugged in 15 minutes before beginning the calibration.
4.1.2 Move the selector on the adapter to the "air" setting.
4.1.3 Turn the slope button
(clockwise).
