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).
