R6/W6
Read/write Units Label
Purpose
Reads or writes the channel's "DISPLAY. UNITS" menu item
Usage
"#aaccR6
↵" to read, "#aaccW6n↵" 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 four-character units label.
↵ is the 'carriage return' character (ASCII decimal 13).
Example
"#0001W6CATS
↵"
Reply
When writing: "OK" or "ERROR".
When reading: a four-character string.
Changing this value doesn't change the mathematically scaling of the channel's values;
that can be changed by altering the "CALIBRATION DATA -> FULL-SCALE VALUE"
menu item and performing a re-calibration.
R7/W7
Read/write Full-scale Range
Purpose
Reads or writes the channel's "FULL-SCALE VOLT" or "FULL-SCALE CURR" menu
items.
Usage
"#aaccR7
↵" to read, "#aaccW7n↵" 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
If the channel's Signal Type Jumpers are set for "voltage", the argument value can be 5
or 10 for 5V or 10V input.
If the channel's Signal Type Jumpers are set for "current", the argument value must be
20 for 4-20mA input.
Example
"#0001W710
↵"
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
re-calibration 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 CAL VALUE" menu items.
Usage
"#aaccR8
↵" to read, "#aaccW8n↵" 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 re-calibrated to the transducer with
the Shunt Calibration method.
R9
Read Signal Type Jumper
Purpose
Read the setting of the Signal Type Jumper
Usage
"#aaccR9
↵"
# is the 'pound' or 'hash' character (ASCII decimal 35).
aa is the two-character instrument address.
cc is the two-character channel number
↵ is the 'carriage return' character (ASCII decimal 13).
Argument
Example
"# 0001R9
↵"
Reply
When reading: an ASCll-floating-point value.
