R7/W7 Read/write Full-Scale Range
Purpose Reads or writes the channel's "FULL SCALE MU/U" menu item
Usage
“ #aacc
R7
↵
” to read, “#aacc
W7
n
↵
” to write
# is the 'pound' or 'hash' character (ASCII decimal 35).
aa is the two-character instrument address. cc is the two-character channel number
n is the full-scale mV/V value.
↵
is the 'carriage return' character (ASCII decimal 13).
Example
“#0001W73.2
↵
”
Reply When writing: " OK " or " ERROR ".
When reading: an ASCll-floating-point value.
Changing this value will change the gain of the amplifier circuit. It is recommended that a
recalibration of the transducer to the channel be performed to maintain calibration.
R8/W8 Read/write Shunt Cal Value
Purpose Reads or writes the channel's "SHUNT CRL URLUE" menu item
Usage
“ aacc
R8
↵
” to read, “#aacc
W8
n
↵
” to write
# is the 'pound' or 'hash' character (ASCII decimal 35).
aa is the two-character instrument address.
cc is the two-character channel number
n is the shunt calibration value in engineering units.
↵
is the 'carriage return' character (ASCII decimal 13).
Example
“#0001W8147.89
↵
”
Reply When writing: " OK " or " ERROR "
When reading: an ASCll-floating-point value.
Changing this value has no effect until the channel is recalibrated to the transducer with
the Shunt Calibration method.
R9/W9 Read/write Excitation Voltage Setting
Purpose Reads or writes the channel's "EXCITATION" menu item
Usage
“#aacc
R9
↵
” to read, “#aacc
W9
n
↵
” to write.
# is the 'pound' or 'hash' character (ASCII decimal 35).
aa is the two-character instrument address.
cc is the two-character channel number
n is the argument defined below.
↵
is the 'carriage return' character (ASCII decimal 13 ).
Argument A value of 0 means 5 volts excitation.
A value of 1 means 10 volts excitation.
Example
“#0001W90
↵
”
Reply When writing: " OK " or " ERROR ".
When reading: an ASCll-floating-point value.
Changing this value will change the excitation voltage to the transducer. It is
recommended that a re-calibration of the transducer to the channel be performed to
maintain calibration.
RK/WK Read/write Known-Load Calibration Point
Purpose Reads or writes the channel's "KNOWN POINT x/y” menu items
Usage
“#aacc
RK
pp
↵
” to read, “#aacc
WK
ppn
↵
” to write.
# is the 'pound' or 'hash' character (ASCII decimal 35).
aa is the two-character instrument address.
cc is the two-character channel number
pp is the parameter defined below.
n is the known-load calibration point in engineering units. .
↵
is the 'carriage return' character (ASCII decimal 13).
Parameter “00" accesses the " KNOWN POINT 1/2 ", " KNOWN POINT 1/3 " or " KNOWN POINT 1/5 "
menu items.
"01" accesses the "
KNOWN POINT 2/5 " menu item.
"02" accesses the " KNOWN POINT 2/3 " and " KNOWN POINT 3/5 " menu items.
