Creating a Standard from a Series of Measurements
NOTE: Auto targeting must be disabled (unchecked) in the Admin/Monitor page to create a
standard from a series of measurements.
1.
Prepare the sample(s) for measurement that will be used for that standard.
2. Click the Measure target button to obtain the first standard measurement.
3. Set the amount of time that elapses between measurements in the Interval fields using
up/down arrows. Time intervals can range from 2 second up to 60 minutes.
4. Click the Start new series button at the bottom of the Monitor dialog to start the
measurement sequence.
5. After the required amount of samples are measured for the average, click the Pause
button.
6. Click the Mean as Target button that appears at the top of the dialog after the Pause
button was clicked. You will be asked to confirm that you want to overwrite the existing
standard. Click Yes to continue.
Clicking the Mean as Target button will change the standard to the mean average of the
series of measurements taken. The target name changes to “Mean” and indicates the
number of samples measured to obtain an average.
IMPORTANT
If you choose your standard from file, and then change the standard to the mean average of
the series of measurements, the tolerances that carried over from the standard from file will
no longer apply. You will need to manually adjust the tolerance to compensate for the
difference in the current mean average vs. the standard from file.
Example: My tolerance is 1.0 DE on L*, a*, and b*. My sample has been running at 0.50 DE
to the standard. I choose to change the standard to the mean average of this series. My new
standard is now 0.5 DE beyond the original standard tolerance. A tolerance of 1.0 means
that I can be running at a DE of 1.5 to the original standard and the instrument will give a
pass indication.
In order to avoid this, the tolerance for the new Standard should be adjusted from 1.0 DE to
0.5 DE.
Also, the new standard created from the mean average cannot be saved or replace the
current standard in file.
Manual Sample Measurement
Manual measurement mode is used to take single sample measurements. Manual should
appear as the trigger method. If not, the option will need to be set as the trigger mode in the
Monitor options page of the Admin dialog.
