SRDG? Sensor Units Input Reading Query
Input SRDG? <input>[term]
Format a
<input> Specifies which input to query: A or B.
Returned <sensor units value>[term]
Format ±nnnnnn
Remarks Also see the RDGST? command.
TEMP? Thermocouple Junction Temperature Query
Input TEMP?[term]
Returned <junction temperature>[term]
Format +nnnnn
Remarks Temperature is in kelvin. This query returns the temperature of the ceramic thermo-
couple block used in the room temperature compensation calculation
TLIMIT Temperature Limit Command
Input TLIMIT <input>,<limit>[term]
Format n+nnnn
<input> Specifies which input to configure: A or B.
<limit> The temperature limit in kelvin for which to shut down all 
control outputs when exceeded. A temperature limit of zero 
turns the temperature limit feature off for the given 
sensor input.
Example TLIMIT B,450[term] if the temperature of the sensor on Input B exceeds 450 K, all
control outputs will be turned off.
Remarks A temperature limit setting of 0 K turns the temperature limit feature off.
TLIMIT? Temperature Limit Query
Input TLIMIT? <input>[term]
Format a
<input> Specifies which input to query: A or B.
Returned < limit>[term]
Format +nnnn (refer to command for description)
TUNEST? Control Tuning Status Query
Input TUNEST?[term]
Returned <tuning status>,<output>,<error status>,<stage status>[term]
Format n,n,n,nn
<tuning status> 0 = no active tuning, 1 = active tuning.
<output> Heater output of the control loop being tuned (if tuning): 
1 = Output 1, 2 = Output 2
<error status> 0 = no tuning error, 1 = tuning error
<stage status> Specifies the current stage in the Autotune process. 
If tuning error occurred, stage status represents stage 
that failed.
Remarks If initial conditions are not met when starting the autotune procedure, causing the
autotuning process to never actually begin, then the error status will be set to 1 and
the stage status will be stage 00.
