Section 6 Calibration Procedures
Calibration Check
During the RUN cycle, if a parameter fails the internal reference/precision checks
for calibration, the value for that parameter is backlit in green on the run line,
dashes are displayed in the Current Factor field, and the Mean Factor is not
updated.
Determining Which Parameters Need Calibration
1. After the
[ACCEPT]
key is displayed, you may continue processing samples
until the desired number of runs has been completed.
2. Observe the Factor % Diff value for each parameter being calibrated:
a. If the value is not highlighted (remains uncolored), that parameter does
not need calibration and the new calibration factor (Mean Factor)
displayed on the screen will not replace the existing calibration factor
when the
[ACCEPT]
key is pressed. An uncolored value indicates the
Factor % Diff is less than the value shown in column 2 of Worksheet 3,
Open Mode Calibration Range Criteria, provided in
Manual Calibration
Worksheets at the end of this section.
b. If the value is highlighted in green, that parameter needs to be calibrated
and the new calibration factor displayed on the screen will replace the
existing calibration factor when the
[ACCEPT]
key is pressed. Green
indicates the Factor % Diff is within the range specified in column 3 of
Worksheet 3, Open Mode Calibration Range Criteria, provided in
Manual Calibration Worksheets at the end of this section.
c. If the value is highlighted in purple, it indicates the Factor % Diff is
greater than the value shown in column 4 of Worksheet 3, Open Mode
Calibration Range Criteria, provided in
Manual Calibration Worksheets
at the end of this section.
d. If all Factor % Diff values are uncolored, go to Calibration Not Required
below. If at least one Factor % Diff is green, go to Some Parameters
Need Calibration below. If at least one Factor % Diff is purple, go to
subsection Over-Limit Parameters below.
Calibration Not Required
1. If all the Factor % Diff values are uncolored, then calibration is not required
in Open Mode. No update to the Calibration Log is required and no
calibration confirmation is required.
2. If Closed Mode has not been calibrated, go to subsection Auto-Cal — Closed
Mode , otherwise return to the
MAIN MENU
by pressing
[RETURN]
followed by
[MAIN]
.
Some Parameters Need Calibration
1. If at least one Factor % Diff value is green and if no Factor % Diff values are
highlighted in purple, press
[ACCEPT]
followed by
[CONFIRM ACCEPT]
to
calibrate the Open Mode. Go to subsection Completing Calibration Log
below.
