[SOUR]:TEMP:THER[:LEVE][:IMM][:AMPL](?)
<DNPD>
Purpose
This command will select Thermocouple function with a default of Type K, setting the required temperature value, which will
determine the output voltage (refer to the Programming Example after paras 6.6.4.21).
<DNPD>
The 'decimal numeric program data' is a number which sets the required temperature value. It must be expressed as a value relating
to the units (degrees Celsius, Degrees Fahrenheit, or Kelvin), already set into the 9100 by the most-recent
TEMP:UNIT <CPD>
command (see paras 6.6.4.18). Power-up and
∗
RST
default units are Celsius.
The value of
<DNPD>
, in conjunction with the '
UNIT
', '
SCAL
' and '
TYPE
' commands, will automatically choose the 'best' hardware
range for the defined thermocouple voltage output.
For details of local operation and parameter limitations, refer to Volume 1, Section 4, Sub-Section 4.14 (Thermocouple
Temperature).
Software Compensation
Software compensation takes account of the temperature of the isothermal block on which the Reference Junction is mounted,
behind the D-type socket on the 9100 front panel (refer to Volume 1, Section 4, Sub-section 4.14.4).
The block temperature is sensed at
OUTPut ON
, and regularly at 5-second intervals until
OUTPut OFF
.
Response to Query Version
The instrument will return a number which is the value of the present output temperature in currently-programmed units. The
returned number will be in standard scientific format (for example: 200
°
C would be returned as
2.0E2
).
6.6.4.21
[SOUR]:TEMP:THER:TYPE(?)
<CPD>{B|C|E|J|K|L|N|R|S|T}
Purpose
This command will select the Thermocouple function with the type selected and a default of 25
°
C. (refer to the Programming
Example below).
<CPD>
The 'character program data' automatically selects the required simulation software. The
<CPD>
'type' character is the same as the
internationally-recognized thermocouple type. Power-up and
∗
RST
default is 'K-type'.
Response to Query Version
The instrument will return the character which represents the presently-programmed thermocouple 'type' simulation:
{B|C|E|J|K|L|N|R|S|T}
.
Programming Example: To ensure the setup of a required thermocouple type and temperature, use:
:TEMP:THER 200;:TEMP:THER:TYPE B<nl>
or
:TEMP:THER 353;:TYPE S<nl>
