Description
Calibration State
Displays the standard currently being measured during the calibration cycle (for example,
Measuring Low, Measuring High, Sample, Recovery Period).
Percentage Complete
A 'real-time' indication of calibration progress.
mV, Low / High
The measured electrode mV of the low standard and high standard of the previous calibration.
Sample Conc. / Millivolts
The raw signal from the measuring electrode shown as a voltage (–2048 to 2047 mV) and also
converted into a concentration value. This value is displayed only when a valid calibration exists.
Last Gradient /
Gradient Coefficient
The Last Gradient is the mV change per decade change in concentrate.
The Gradient Coefficient is an indication of the difference between the calculated calibration
gradient and the Nernstian calibration gradient.
If the gradient exceeds the limits set by the user, the analyzer fails calibration. Default fail criteria
occurs when the coefficient is outside the range 0.4 to 1.6.
mV Offset / %Slope
mV offset is the mV difference from the expected mV value for any standard, compared to a
reference value.
% slope is the slope compared to the theoretical temperature-compensated change in mV
(% absolute).
Time Last Calibration
The date and time of the previous calibration.
Fields
Description

Buffer
Displays the buffer solution level sensor reading (empty or OK).
Clean Sol
Displays the cleaning solution level sensor reading (empty or OK).
