EMUL Model 331/332 Interface Emulation Mode Command
Input EMUL <emulation mode>,<PID scaling mode>[term]
Format nn
<emulation mode> 0=None (335), 1=331, 2=332
<PID scaling mode> PID control scaling: 0=335 (Temperature), 1=331/332
(Sensor)
Remarks The 331 and 332 emulation modes provide a means of using the Model 335 in place
of a Model 331 or 332 in a software controlled system without updating the software.
The emulation mode setting only affects remote operation; front panel operation of
the Model 335 is not changed. Please reference the Model 331 or 332 user’s manual
for information on the interface commands for those models. For more information
on using the emulation modes, see
section 5.11.
EMUL? Model 331/332 Interface Emulation Mode Query
Input EMUL? [term]
Returned <emulation mode>,<PID scaling mode>[term]
Format n,n (refer to command for description)
FILTER Input Filter Parameter Command
Input FILTER <input>,<off/on>,<points>,<window>[term]
Format a,n,nn,nn
<input> Specifies input to configure: A or B.
<off/on> Specifies whether the filter function is 0 = Off or 1 = On.
<points> Specifies how many data points the filtering function uses.
Valid range = 2–64.
<window> Specifies what percent of full scale reading limits the filtering function.
Reading changes greater than this percentage reset the filter. Valid
range = 1 to 10%.
Example FILTER B,1,10,2[term] filter input B data through ten readings with 2% of
full scale window.
FILTER? Input Filter Parameter Query
Input FILTER? <input>[term]
Format a
<input> Specifies input to query: A or B.
Returned <off/on >,<points>,<window>[term]
Format n,nn,nn (refer to command for description)
HTR? Heater Output Query
Input HTR? <output>[term]
Format n
<output> Heater output to query: 1 = Output 1, 2 = Output 2
Returned <heater value>[term]
Format ±nnn.n
<heater value> Percent of full scale current for Output 1 and Output 2 in
Current mode, or percent of full scale voltage for Output 2
in Voltage mode.
