Physical Inputs & Outputs
2. Define the input operating range by entering the Minimum mA and Maximum
mA into the corresponding textboxes.
3. In the Min Value @ Min mA textbox, enter the minimum value, in engineering
units, that corresponds to the value entered in the Minimum mA textbox.
4. In the Max Value @ Max mA textbox, enter the maximum value, in engineering
units, that corresponds to the value entered in the Maximum mA textbox.
5. Additional fields on this screen, which are listed below, are for display purposes
only and are not configurable by the user.
•
Live Value (EU) – This field displays the live calibrated value in engineering
units in both Live and Manual modes.
•
Raw Value (mA) – This field displays the live calibrated value in milliamps in
both Live and Manual modes.
•
#1 mA Min Value – This field displays the expected minimum analog input
value provided by the user during calibration.
•
#2 mA Mid Value – This field displays the expected midpoint analog input
value in a three point calibration provided by the user during calibration.
•
#3 mA Max Value – This field displays the expected maximum analog input
value provided by the user during calibration.
•
#1 Raw Min Value – This field displays the measured minimum value read
from the device.
•
#2 Raw Mid Value – This field displays the measured midpoint value read
from the device.
•
#3 Raw Max Value – This field displays the measured maximum value read
from the device.
•
Calibration Points – This field displays the number of points the current
information used to calibrate the current input.
•
Status – This field displays Live or Manual, depending on the operating mode
selected, as well as low and high alarm conditions.
Calibration All four of the current inputs can be calibrated using two or three calibration points.
The calibration process for the current inputs should be completed by selecting
Calibration from the Functions menu or by clicking the fourth icon button, the
wrench. Selecting either of these options will guide the user through the calibration
process step-by-step. For further information, see
Calibration .
