Change the configuration to STEPS of 10%, 20%, 25%, VARIABLE or press
C/CE to maintain the configuration already stored in memory. The temperature range
of the program must be configured through the values in SET POINT HIGH and SET
POINT LOW in case of 10%, 20% or 25% fixed steps of the range. The option
VARIABLE allows the user to define from 2 to 11 values of temperature set point, not
necessarily in ascending order.
To verify the step values of a program, select the VARIABLE option and
confirm the values shown in the display with the key ENTER. The 10%, 20% and 25%
options change the number of steps automatically and recalculate the values according
to SET POINT HIGH and SET POINT LOW.
SC: This function scales the input reading of pyrometric transmitters. The
scaling is very useful in temperature transmitter calibration, for instance, because it
displays the current temperature and the transmitter reading in the same unit. Thus,
the error can be verified directly in ºC or ºF. Select the option SC and press ENTER. If
no input is selected in IN, the calibrator will show the SELECT INPUT FIRST message.
In this case, go to menu IN and select the input signal type.
The function SC will show IN or NO. Confirm IN to configure the scaling or NO
to disable the SC function, with the key ENTER.
The scaling is performed via the INPUT HIGH and INPUT LOW parameters,
corresponding to the maximum and minimum values of the calibrator signal input, in
the engineering unit of this signal. Next, configure the SCALE DEC (0-4), SCALE
HIGH and SCALE LOW parameters according to the maximum and minimum values
of the transmitter scale and the desired number of decimals. The scaled value is
shown on the display with the # unit.
For example, temperature transmitter with 0 to 100 ºC input and 4 to 20 mA
output. The scaling with one decimal would be:
INPUT HIGH: 20.0000 mA
INPUT LOW: 4.0000 mA
SCALE DEC (0-4): 1
SCALE HIGH: 100.0 #
SCALE LOW: 0.0 #
