10. Tune the FC 217 block specification 5 to the input voltage
or resistance value. For this example, tune these
specifications:
a. perform point calibration
S1 = 2
b. the slave referenced by FC 215
S2 = 100
at block address 100
c.
slave channel 1
S3 = 1
d. calibration type 0 (low level)
S4 = 0
e.
calibration parameter 1 - 100
S5 = -100
(millivolts)
Successful field calibration operations can be verified by
checking for a zero value in FC 217 blocks N+1 and N+4. If the
point calibration was unsuccessful, an error code will appear
in the FC 217 blocks N+1 and N+4 which can aid in
troubleshooting.
11. Change the calibration voltage (source output) to the next
desired value (this example calls for -80 mV) and wait the 15
second settling time.
12. Tune the FC 217 block to the next higher value in the cali-
bration range. In this example, tune specification 5 to:
a. perform point calibration
S1 = 2
b. the slave referenced by FC 215
S2 = 100
at block address 100
c.
slave channel 1
S3 = 1
d. calibration type 0 (low level)
S4 = 0
e.
calibration parameter 1 - 80
S5 = -80
(millivolts)
13. Successful field calibration operations can be verified by
checking for a zero value in FC 217 blocks N+1 and N+4 for a
zero value. If the point calibration was unsuccessful, an error
code will appear in the FC 217 blocks N+1 and N+4 which can
aid in troubleshooting.
At this step two points have been field calibrated and the
enable calibration command can be executed. For greater
channel nonlinearity, calibrate additional points by repeating
Steps 7 through 12 for each additional point. A maximum of 11
points can be specified for a given input range on each chan-
nel. The three input ranges are low level, high level, or RTD.
