Cold Cycle Indicator:
When this Blue L.E.D. is illuminated, the unit is cooling down the target plate.
NOTE:
P.I.D. Control:
Proportional, integral, derivative control ( P.I.D.) is a temperature control algorithm
used in high-end temperature controllers. The controller causes the process to
attain the desired temperature by turning the process on or off. The process may
be a heater or refrigerator. As the process temperature approaches the setpoint
temperature the hot or cold process will be pulsed to reduce the corrective measures
and minimize overshooting. The controller provides a visual representation of the
process status through LED indicators. An indicator may be lit continuously, blink or
shut off entirely to indicate that the process is on, being pulsed, or off, respectively.
Parameter/Access Key:
Press to scroll through menu parameters
Raise Key:
Press to increase the selected parameter or scroll upward in the list of possible
settings.
Lower Key:
Press to decrease the selected parameter or scroll downward in the list of
possible settings.
Mode Key:
Press to save settings and exit a menu level.
Target Plate:
The 2.5" target plate is a near ideal blackbody source. The emissivity of the plate
is 0.95. When calibrating an IR pyrometer, hold the pyrometer perpendicular to
the target plate for optimal performance. The proper distance between the IR
pyrometer and the target plate depends on the field of view of the pyrometer.
If the pyrometer is too far away it will scan unwanted surfaces outside of the
perimeter of the target plate. Holding the pyrometer too close could introduce
undesirable heat to the IR detector of the pyrometer.
