4.7.3 Download other parameters into volatile memory
4.7.3.1 For Non-digitally Compensated 9400 Sensors Without Non-volatile Memory
or Non-9400 Sensors
A user-defined date can be downloaded into volatile memory using the ‘v’
command with coefficient index 07. A manufacturing reference or serial
number can be downloaded into volatile memory using the ‘v’ command
with coefficient index 09 (format=5). A transducer full-scale range code can
be downloaded into volatile memory using the ‘v’ command with coefficient
index 0A. User-defined range codes can be assigned to values 128 and up
(format=5). (See User’s Manual, Appendix E for standard Range Codes.)
4.7.3.2 For Non-digitally Compensated 9400 Sensors With Non-volatile Memory
For non-digitally compensated 9400 sensors with non-volatile memory, the
same commands apply as for non-9400 “generic” (third party) sensors. The
difference is that for non-digitally compensated 9400 sensors, upon
command, parameters are immediately stored into the sensor’s non-volatile
memory.
4.7.4 Set parameters to factory defaults
4.7.4.1 For Non-digitally Compensated 9400 Sensors Without Non-volatile Memory
or Non-9400 Sensors
All of the above parameters can be set to factory defaults using the ‘w’
command with index 25. For each third-party type sensor attached, this
command sets the volatile copy of each parameter back to the factory default
value as follows:
Offset term = 0.0
Gain term = 1.0
c0 = 0.0
c1 = 1.0
c2 = 0.0
c3 = 0.0
user-defined date = 0
manufacturing reference number = 0
full-scale range code = 0
front end gain = 0 (unity).
