OPERATION
If a manual calibration is selected then both the ‘Interval’ and ‘Hour’ selection boxes
are hidden, as shown above. If an automatic calibration is selected then the “Calibrate”,
“Cal Source” and “Ext Ref” selection boxes are hidden, as shown below:
Figure 20 Field Calibration Screen 4
• Interval (Days) – This is where the user selects how often in days a
calibration is performed.
• Hour of Day – This is where the user selects the hour within the day at
which the calibration will occur.
• Cal Cycles – This is where the user selects how many calibration cycles
are carried out.
• Settling Cycles – This is where the user selects how many settling cycles
are added after the calibration.
NB. If a manual calibration has been started the page will hide all the
parameter and instead show the calibration and settling cycle countdown.
This can be seen below:
