Figure 36. Reading Standard Values
For a HITCH standard, place the hitch standard (with known values from a reference
instrument) at the sample port and press the GO button ( READ ) to read the standard and place
its measurement values (in the selected color).
Tolerances
When Tolerances are highlighted, press the RIGHT ARROW button to move to the TOLERANCES
configuration screen, on which you may set tolerances in the chosen color scale and color
index.
Figure 37. Tolerances Setup
There are 3 sets of Tolerances that may be selected: COLOR TRACKING (if enabled), ALARM
LIMITS , and ALERT LIMITS .
COLOR TOLERANCES: COLOR TRACKING
Choose whether COLOR TRACKING is enabled by setting the tolerances. When all
tolerance values are set to zero, the COLOR TRACKING feature is disabled. When Color
Tracking is enabled, (a non-zero value is set) product will only register as present if the
measured color is within the preset range (in absolute mode) or within a tolerance band
of the target color (in difference mode). In this case, the number of valid color readings
per sample measurement interval will be displayed in the upper left hand corner of the
display for the current sample measurement. If the value of the valid samples per
measurement is zero, no product is being measured.
