CAL CALIBRATION
CAL=MXB [CMT]
Sets the active calibration method to "MXB" (i.e., "TWO-POINT" or "CALCULATED" cali-
bration using the "y = mx+b" linear equation). For RS-485 (only), returns ACK [EOT].
CAL=LIN [CMT]
Sets the active calibration method to "15-SEGMENT LINEARIZATION." Not recognized
by the Model 3510 Thermocouple Conditioner. For RS-485 (only), returns ACK
[EOT].
CAL [CMT]
Reads the currently active calibration method. Returns MXB [EOT] or LIN [EOT],
except for the Model 3510 Thermocouple Conditioner, which can only return MXB
[EOT].
CHN CHANNEL
CHN [CMT]
Reads the current measurement data. Outputs LBLn,w,sEUS [EOT], where LBL =
header string (optional—see LABEL (LBL) command); n = node number (optional—
see ECHO (ECO) command); w = data value; s = limit-status indicator number (option-
al—see LIMITS (LIM) command); EUS = tailer string (optional—see ENGINEERING
UNIT STRING (EUS) command).
CMT COMMAND TERMINATOR
CMT=c [CMT]
Specifies the single ASCII CONTROL CHARACTER c to be recognized as the INPUT
(or "COMMAND") TERMINATOR for all commands received via the RS-232/485 Inter-
face Port; c must be entered as a hexadecimal byte in square brackets ([01] through
[1F]). CMT must be the same for all network nodes, and cannot be the ASCII [ESC]
character. For RS-485 (only), returns ACK [EOT].
CMT [CMT]
Reads the currently effective COMMAND TERMINATOR. Returns c [EOT].
DMP DUMP
DMP [CMT]
Same as CHANNEL (CHN) command, above.
ECO ECHO
ECO=ON [CMT]
Causes the 3500 instrument's NODE NUMBER to be included in all transmissions from
the RS-232/485 Interface Port in response to a CHANNEL (CHN) or DUMP (DMP)
command. For RS-485 (only), returns ACK [EOT].
ECO=OFF [CMT]
Cancels Node-Number "echo" for CHN and DMP transmissions. For RS-485 (only),
returns ACK [EOT].
ECO [CMT]
Reads current Node-Number "echo" status. Returns ON [EOT] or OFF [EOT].
EMM SCALING FACTOR
EMM=m [CMT]
Sets to m the SCALING FACTOR to be applied to the data reading, where -32700 ≤ m ≤
32700. Also sets desired precision (decimal-point location). For RS-485 (only),
returns ACK [EOT].
IMPORTANT: THIS COMMAND SHOULD ONLY BE APPLIED WHEN THE 3500
INSTRUMENT IS SET FOR "TWO-POINT" OR "CALCULATED" CALIBRATION— THAT IS,
WHEN THE CAL=MXB [CMT] COMMAND IS IN EFFECT. IF ENTERED WHEN
CAL=LIN [CMT], UNPREDICTABLE READINGS COULD OCCUR.
EMM [CMT]
Reads current SCALING FACTOR. Returns m [EOT].
