Field Calibration
10. Tune FC 217, specification S5 to the input voltage or resis-
tance value. For this example, tune these specifications:
a. Perform point calibration (S1 = 2).
b. ASI module referenced by FC 215 at block address 100
(S2 = 100).
c. ASI module channel one (S3 = 1).
d. Calibration type zero (low level) (S4 = 0).
e. Calibration parameter 1 - 100 (millivolts) (S5 = 100).
Successful field calibration operations can be verified by
checking for a zero value in FC 217, output N+1 and N+4. If
the point calibration was unsuccessful, an error code will
appear in the FC 217, outputs N+1 and N+4 which can aid in
troubleshooting.
11. Successful field calibration operations can be verified by
checking for a zero value in FC 217, outputs N+1 and N+4 for a
zero value. If the point calibration was unsuccessful, an error
code will appear in the FC 217, outputs N+1 and N+4 which
can aid in troubleshooting.
At this step, two points have been field calibrated (0 and full
scale) and the enable calibration command can be executed.
The three input ranges are low level, high level, or RTD.
If desired, repeat Steps 7 through 10 for channels 2 through
16 to calibrate all 16 channels on the ASI module.
12. Enable the point. Tune the FC 217, specification S1 to
enable the channel. For this example, tune these
specifications:
a. Enable the channel (S1 = 3).
b. ASI module referenced by FC 215 at block address 100
(S2=100).
c. ASI module channel one (S3 = 1).
d. Calibration type x (S4 = x). x is a do not care value.
e. Calibration parameter x (S5 = x).
