2.5 - Automatic Operating Mode
The infrared thermometer calibration is performed in an automatic way by the
T-500PIR calibrator. The configuration, as well as the calibration verification is carried
out by the calibrator itself. Also it is possible to use the ISOPLAN software and its work
orders, like a CAC - Computer Aided Calibration.
The independent automatic calibration, without the use of ISOPLAN, is planned
in the option TAGMAN from menu COM.
Before start programming, configure the signal that will be read by the calibrator
in the menu IN. To calibrate pyrometers with local indication, for example, there is no
electric signal to be read. In this case, option IN from the menu must be configured to
NO and the calibrator will ask to enter the value indicated by the pyrometer, at the end
of the stabilization time of each calibration point.
The data for an automatic calibration are:
• TAG: the pyrometer tag identification.
• SP: the black body cavity temperature reference values for the calibration
(calibration points).
• TOL: the maximum tolerance for the pyrometer operation.
• STB: the stabilization time, in seconds, so that the pyrometer reading can be taken.
This timer starts just after the cavity reaches and stabilizes at the set point
temperature.
• STR: the calibration strategy of the programmed reference values. The available
strategies are:
(UP - DOWN - UP) and
• RP: the strategy number of repetitions.
• RGI: the pyrometer indication range.
• RGO: the operating temperature range that corresponds to the indication range
above.
The automatic calibration begins when the option EXEC from menu COM is
selected. All the operations are automatically performed by the T-500PIR calibrator.
The keypad does not work until the end of the calibration.
At the end of the stabilization time, the calibrator stores the thermometer reading
in memory and goes to the next point, in case some input signal has been previously
configured in the menu IN and connected to the calibrator terminals.
The CALIBRATION END message appears on the display at the end of the
automatic calibration. Press ENTER to confirm. The results can be verified in option
VERIF from menu COM.
The first message in option VERIF informs the calibration result, with the number
of points that have succeeded or not. Following, press ENTER to verify each one of the
