INTYPE Input Type Parameter Command
Input INTYPE <input>,<sensor type>,<autorange>,<range>,<compensa-
tion>,<units> [term]
Format a,n,n,n,n,n
<input> Specifies input to configure: A or B
<sensor type> Specifies input sensor type:
0 = Disabled
1 = Diode
2 = Platinum RTD
3 = NTC RTD
4 = Thermocouple
<autorange> Specifies autoranging: 0 = off and 1 = on.
<range> Specifies input range when autorange is off:
Input range
Diode 0 = 2.5 V
1 = 10 V
PTC RTD 0 = 10 )
1 = 30 )
2 = 100 )
3 = 300 )
4 = 1 k)
5 = 3 k)
6 = 10 k)
NTC RTD 0 = 10 )
1 = 30 )
2 = 100 )
3 = 300 )
4 = 1 k)
5 = 3 k)
6 = 10 k)
7 = 30 k)
8 = 100 k)
Thermocouple 0 = 50 mV
<compensation> Specifies input compensation where 0 = off and 1 = on. Reversal for 
thermal EMF compensation if input is resistive, room compensation 
if input is thermocouple. Always 0 if input is a diode.
<units> Specifies the preferred units parame
ter for sensor readings and for 
the control setpoint: 1 = kelvin, 2 = Celsius, 3 = Sensor
Example INTYPE A,2,1,0,1,1[term] sets Input A sensor type to Platinum RTD, autorange on,
thermal compensation on, and preferred units
to kelvin.
Remarks The <autorange> and <range> parameters do not apply to thermocouple sensor type,
an
d the <autorange> and <compensation> parameters do not apply to diode sensor
type. When configuring diode or thermocouple sensor types, these parameters must
be included, but are ignored. A setting of 0 for each is recommended in this case.
INTYPE? Input Type Parameter Query
Input INTYPE? <input>[term]
Format a
<input> Specifies input to query: A or B.
Returned <sensor type>,<autorange>,<range>,<compensation>,<units> [term]
Format n,n,n,n,n (refer to command for description)
Remarks If autorange is on, the returned range param
eter is the currently auto-selected range.
