Calibrating Standard 2
The upper display shows the chloride concentration value based on the previous good
calibration figures. The lower display remains until a stable output is obtained from the
electrodes.

normal operation.
When a stable output is detected the display automatically advances to the next
parameter, and the upper display is updated to the value of "Std 2".
Calibration Passed
A satisfactory calibration has been carried out.
or
Calibration Failed (slope)
The monitor was unable to obtain an acceptable slope value during calibration. The
slope value required is 80 to 110%.
or
Calibration Failed (slow)
The monitor was unable to obtain a stable output from the electrodes during
