8 - TEMPERATURE - A (CONTINUED)
CALIBRATE LOW
85
With this setting it is possible to calibrate the input value for (0)4mA as the
signal from the sensor might not be exact 4.0 mA (or 0.0 mA) at “offset-
temperature” - SETUP 83.
This function will measure the real output value at “offset-temperature”.
Warning: be very sure that the offered signal is correct
before the calibration is executed as this function has major
influences on the accuracy of the system!
After pressing PROG, three settings can be selected:
CALIBRATE: with this setting, the input will be calibrated with the
actual “(0)4mA” value. After pressing enter, CAL SET will be
displayed as soon as the calibration is completed. From that moment,
the analog value must be more than the calibrated value before the
signal will be processed.
DEFAULT: with this setting, the manufactures value is re-installed.
CAL SET: to select the last calibrated value.
CALIBRATE HIGH
86
With this setting it is possible to calibrate the input value for 20mA as the
signal from the sensor might not be exact 20.0 mA at maximum
temperature (which is the offset-value plus the Span value).
This function will measure the real output value at maximum temperature.
Warning: be very sure that the offered signal is correct
before the calibration is executed as this function has major
influences on the accuracy of the system!
After pressing PROG, three settings can be selected:
CALIBRATE: with this setting, the input will be calibrated with the
actual “20mA” value. After pressing enter, CAL SET will be displayed
as soon as the calibration is completed. From that moment, the
analog value must be less than the calibrated value for a reliable
measurement.
DEFAULT: with this setting, the manufactures value is re-installed.
CAL SET: to select the last calibrated value.
