A.3.36 Transducer Channel (SCC)
Command:
ref#,r1#,r2#,s/r#SCC
Includes DC Reference, and Shunt Resistance Values – Set or Return (see
Note 1 on page 105). Sets or returns the transducer channel DC reference
and shunt resistance values as follows:
ref# Reference voltage in volts
r1# 9 ohm shunt resistance in ohms. This calibrates the
1 to 100 mA DC current ranges.
r2# 1000 ohm plus 9 ohm shunt resistance in ohms. This
calibrates the 0 to 1 mA DC current ranges.
s/r#
0
To store reference and resistance values.
1 To send reference and resistance values.
A.3.37 Serial Number (SER)
Command:
serial#,s/r#SER
Sets or returns instrument Serial Number. See Note 1 on page 105.
Serial# (s/r#) ASCII number (5 digits)

1. If no numbers present, it starts a new file
2. If 1 number present: 0 = disable flash, 1 = enable flash
3. If 3 numbers present:
#1 = 0 manual trigger from LOG DATA key or RS-232
Log command
#1 = 1 trigger from timer
#1 = 2 auto trigger with period set by #2
#2 = 1 to 86400 auto log store trigger period in sec
#3 = 32 bit data descriptor entered as decimal number
4. If 7 numbers present
#1 = 0 #2 . . . #7 = autolog start time
#1 = 1 #2 . . . #7 = autolog stop time
#2 = yyyy year
