d. TEMPerature:TCouple:RJUNction:SIMulated <n> [, <clist>]
The units for the simulated reference temperature depend on the present
temperature measurement units as set by UNIT:TEMPerature (see Ref h).
NOTE The following command can instead be used to set the simulated
reference temperature:
TEMPerature:RJUNction:SIMulated <n> [, <clist>]
e. TEMPerature:FRTD:RZERo <NRf> [, <clist>]
TEMPerature:FRTD:ALPHa <NRf> [, <clist>]
TEMPerature:FRTD:BETA <NRf> [, <clist>]
TEMPerature:FRTD:DELTa <NRf> [, <clist>]
These commands are used to set the parameters for the USER RTD type. Note
that the RZERo command sets the “Ω at 0°C” parameter. When any of these
commands are sent, the USER RTD type is automatically selected.
f. FREQuency:THReshold:VOLTage:RANGe <n> [, <clist>]
PERiod:THReshold:VOLTage:RANGe <n> [, <clist>]
These commands are used to specify the expected input level. The instrument
will then automatically select the most sensitive current or voltage threshold
range.
g. FREQuency:APERture <n> [, <clist>]
PERiod:APERture <n> [, <clist>]
The rate annunciators indicate the following aperture settings:
SLOW = 1 sec
MED = 0.1 sec
FAST = 0.01 sec
For all other aperture times, the rate annunciators are turned off.
h. UNIT:TEMPerature <name>
To set temperature measurement units to °C, use the C or CEL parameter. For
°F, use the F or FAR parameter. For Kelvin, use the K parameter.
i. Trigger and retrieve readings:
NOTE Detailed information on the processes to trigger and retrieve read-
ings is provided in Section 8, Section 13, and Appendix D.
INITiate:CONTinuous <b>
INITiate
With continuous initiation disabled (INITiate:CONTinuous OFF), you can use
the INITiate command to trigger one or more measurements.
NOTE Note that sending INITiate while the instrument is performing
measurements will cause error -213 (init ignored).
