NOTE: The calculated gain values from the latest ‘Z’ command will be lost
when the module is powered off. To save these gain terms to each
transducer’s non-volatile memory, refer to the Set Operating Options (‘w’)
command (index 09).
Notice that unlike the Calculate and Set Offsets (‘h’) command, this command does
not automatically move a 9016 module’s calibration valve to its Cal position. A
command to do this must precede this command. The reader is referred to Chapter
4, Section 4.3 for additional details concerning the performance of a Span
Calibration.
Internal firmware limits calculated gains to values are software limited to values
between 0.0 and 100.0. Any calculated value outside of this range will result in the
gain coefficient being set to 1.00.
Example:
! Send TCP/IP command to a module (via its open socket) to calculate and set gain
coefficients for channels 8 through 4. Instruct the module to use 14.8890 psi as the
applied pressure instead of each transducer’s full-scale value:
“Z00F8 14.8890”
Read response, containing the new gain values (also stored in the module’s volatile
main memory):
“1.000212 1.000269 1.000437 1.000145 .999670”
Actual gain values are returned in the above response as decimal ASCII strings, each
preceded by a space character. From left-to-right: they are for channels 8, 7, 6, 5,
and 4.
