measured phenomenon, expressed in the desired engineering units and precision).
For RS-485 (only), returns
ACK [EOT] .
IMPORTANT: THIS COMMAND SHOULD ONLY BE APPLIED WHEN THE 3540 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.
FRQ [CMT]
Reads current "FRQ" calibration constants. Returns i,u [EOT] . See Section 4.d.4
regarding the answer returned in response to an FRQ [CMT] interrogation.
HHY HIGH HYSTERESIS
HHY=p [CMT]
Sets the HIGH HYSTERESIS window depth to p (where p is a percentage of the exist-
ing SCALING FACTOR ("m") value to the nearest tenth of a percent). For RS-485 (only),
returns
ACK [EOT] .
HHY [CMT]
Reads current HIGH HYSTERESIS window depth. Returns p [EOT] .
HIL HIGH LIMIT
HIL=h [CMT]
Sets the HIGH LIMIT value to h (-32700
≤
h
≤
32700; h must be greater than or equal to
the existing LOW LIMIT (LOL) value). For RS-485 (only), returns ACK [EOT] .
HIL [CMT]
Reads current HIGH LIMIT value. Returns h [EOT] .
HLA HIGH LATCH
HLA=ON [CMT]
Sets the HIGH LIMIT to LATCHING status. For RS-485 (only), returns ACK [EOT] .
HLA=OFF [CMT]
Sets the HIGH LIMIT to NONLATCHING status. For RS-485 (only), returns ACK [EOT] .
HLA [CMT]
Reads current HIGH-LIMIT LATCH status. Returns ON [EOT] or OFF [EOT] .
LBL LABEL
LBL=$ [CMT]
Specifies "header" string $ for all transmissions from the RS-232/485 Interface Port in
response to a
CHANNEL (CHN) or DUMP (DMP) command ($ is a string of up to 8
characters, including spaces). For RS-485 (only), returns ACK [EOT] .
LBL=N/A [CMT]
Clears all characters from the existing "header" string. For RS-485 (only), returns ACK
[EOT] .
LBL [CMT]
Reads current "header" string. Returns $ [EOT] or N/A [EOT] .
LFC LINEARIZATION FORCE
LFC=V [CMT]
Sets to v the OUTPUT value for the linearization segment corresponding to the exist-
ing "live" INPUT. Not recognized by the
Model 3510 Thermocouple Conditioner .
For RS-485 (only), returns ACK [EOT] .
[ NOTE: There is no valid interrogation form for the LFC command.]
LHY LOW HYSTERESIS
LHY=p [CMT]
Sets the LOW HYSTERESIS window depth to p (where p is a percentage of the exist-
ing SCALING FACTOR ("m") value to the nearest tenth of a percent). For RS-485 (only),
returns
ACK [EOT] .
