8.6 Calibration results
After the slope and offset have been calculated, the default parameters, last calibration details
and current calibration details are displayed, along with a “Calibration ok” or “Calibration
error” message.
The criteria for accepting or rejecting the calibration is as follows:
• The slope must be within ± 10% of the standard slope
• The offset must be within ± 59 mV from the reference point
If the calibration is accepted, the parameters are updated and the instrument returns to the
normal measurement mode after a short delay.
If the calibration is rejected an alarm is set and the parameters remain unchanged. After a short
delay the analyzer returns to the normal measurement mode.
For details of the calibration results, select the calibration loggings option as described below.
8.7 Calibration loggings
Select the CALIBRATION LOGGINGS option to view
historical information about previous calibrations.
The screen will list the following information about previous
calibrations:
• Date and time.
• Whether the calibration was automatic or manual.
• The values of the slope and offset.
