6.6.4.22
[SOUR]:TEMP:PRT[:LEVE][:IMM][:AMPL](?) <DNPD>
Purpose
This command selects PRT simulation hardware, and sets the required temperature value, which determines the output resistance,
once the type of PRT has been selected (refer to paras 6.6.4.23 and to the Programming Example after paras 6.6.4.25).
<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. For this command sent on its own; other defaults
are: NRES = 100
Ω
, TYPE = PT385 and UUT_I = HIGH.
The value of
<DNPD>
, in conjunction with the '
UNIT
', '
SCAL
' and '
TYPE
' commands, will automatically choose the 'best' hardware
range for the defined PRT resistance output.
For details of local operation and parameter limitations, refer to Volume 1, Section 4, Sub-Section 4.15 (RTD Temperature).
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
).
6.6.4.23
[SOUR]:TEMP:PRT:TYPE(?) <CPD>{PT385|PT392}
Purpose
This command selects the appropriate conversion software to simulate the selected RTD type (refer to the Programming Example
after paras 6.6.4.25).
<CPD>
The 'character program data' selects the required simulation software for the required type of RTD:
PT385
For subsequent commands
TEMP:PRT <DNPD>
, the 9100 will use the PT385 (European) conformance curve.
PT392
For subsequent commands
TEMP:PRT <DNPD>
, the 9100 will use the PT392 (USA) conformance curve.
Power-up and
∗
RST
default is 'PT385'. For this command sent on its own; other defaults are: LEVE = 25
°
C, NRES = 100
Ω
and
UUT_I = HIGH.
Response to Query Version
The instrument will return the characters which represent the presently-programmed RTD 'type' simulation:
{PT385|PT390}
.
