HTR?
Heater Output Query
Input:
HTR?[term]
Returned:
<heater value>[term]
Format:
+nnn.n
<heater value>
Loop 1 heater output in percent (%). Use AOUT? for Loop 2.
HTRST?
Heater Status Query
Input:
HTRST?[term]
Returned:
<error code>[term]
Format:
n
<error code>
Heater error code: 0 = no error, 1 = heater open load, 2 = heater short.
IEEE
IEEE-488 Interface Parameter Command
Input:
IEEE <terminator>, <EOI enable>, <address>[term]
Format:
n,n,nn
<terminator>
Specifies the terminator. Valid entries: 0 = <CR><LF>,1 = <LF><CR>,
2 = <LF>, 3 = no terminator (must have EOI enabled).
<EOI enable> Sets EOI mode: 0 = enabled, 1 = disabled.
<address>
Specifies the IEEE address: 1
–
30. (Address 0 and 31 are reserved.)
Example: IEEE
0,0,4[term]
– After receipt of the current terminator, the instrument uses EOI mode,
uses <CR><LF> as the new terminator, and responds to address 4.

IEEE-488 Interface Parameter Query
Input:
IEEE?[term]
Returned:
<terminator>, <EOI enable>, <address>[term]
Format:
n,n,nn
(Refer to command for description)
INCRV
Input Curve Number Command
Input:
INCRV <input>, <curve number>[term]
Format:
a,nn
<input>
Specifies which input to configure: A or B.
<curve number> Specifies which curve the input uses. If specified curve parameters do
not match the input, the curve number defaults to 0. Valid entries:
0 = none, 1
–
20 = standard curves, 21
–
41 = user curves.
Remarks:
Specifies the curve an input uses for temperature conversion.
Example: INCRV
A,23[term]
– Input A uses User Curve 23 for temperature conversion.
INCRV?
Input Curve Number Query
Input:
INCRV? <input>[term]
Format:
a
<input>
Specifies which input to query: A or B.
Returned:
<curve number>[term]
Format:
nn
