Sets all measurement parameters and trigger parameters to their
for temperature meas-
urements and immediately triggers a measurement. The results are sent directly to the instrument's out-
put buffer.

>: {FRTD|RTD|FTHermistor|THERmistor|TCouple}. Default: FRTD.
(none)
<
type
>: 85 (only possible value for RTD/FRTD), 5000 (only possible value for THERmis-
tor/FTHermistor), or E, J, K, N, R, T (TCouple).

The
default is equivalent to 10 PLC.
Configure a 4-wire RTD measurement with default resolution. Then make and read one measurement:

Thermocouple measurements (TC) apply only to the 34465A and 34470A.
l
For temperature measurements, the instrument internally selects the range; you cannot select the
range to be used. The range ("1" is the only allowed value) is used only in conjunction with resolution
to determine NPLC.
l
The <
resolution
>parameter only determines the integration time; it does not specify the resolution of
the temperature measurement. This parameter is optional; however, if you specify <
resolution
>, you
must also specify "1" as the implied range parameter. For example:
CONF:TEMP
RTD,85,1,0.000001
selects the 10 PLC integration time on the 34461A.

For RTD and thermistor measurements, the instrument autoranges to the correct range for the trans-
ducer resistance measurement. For thermocouple measurements, the 100 mV range is selected.

For thermocouple measurements, the internal reference is selected. See

If the input signal is greater than can be measured on the specified manual range, the instrument dis-
plays the word
