FUNCTION CODE DEFINITIONS
ENHANCED CALIBRATION COMMAND FUNCTION CODE (FC 217)
C - 14
I-E96-301B
®
For command code 2, point calibration, this parameter speci-
fies the true value of the signal applied to the input channel
during the calibration operation. Enter S5 for each calibration
point (twice if two points on a channel are calibrated). Up to 11
points may be identified for adjustment of input channel non-
linearities, resulting in 10 linear segments for correction.
These calibration points may be applied in any order. The units
for the point value are determined by the type of calibration
operation specified in S4.
For user gain and offset applications, S5 specifies the gain and
S6 specifies the offset. When the IMASI03 is shipped, the
default value for gain is set to one and the default value for off-
set is set to zero. This command sets both the gain and offset
parameters simultaneously each time it is entered.
Example:
Low-level
=
millivolts (-100.0 to +100.0)
High-level
=
Volts (-10.0 to +10.0)
RTD
=
Ohms (5.0 to 500)
For command code 5, user gain and offset adjustment, this
parameter specifies the gain, or slope, of the linear correction
to be applied. Both user gain and offset adjustment can be
changed at one time.
S6
Calibration parameter 2 provides a real value dependent upon
the type of command specified in S1.
For command code 5, user gain and offset adjustment, this
parameter specifies the offset, or intercept, of the linear correc-
tion to be applied. The units for the offset value are determined
by the type of calibration operation specified in S4.
Example:
Low-level
=
millivolts (-100.0 to +100.0)
High-level
=
Volts (-10.0 to +10.0)
RTD
=
Ohms (5.0 to 500)
