MEASure:TEMPerature? {RTDFRTD},{8591DEF}

[,1[,< >MINMAXDEF}]] ,(@< >)

Configure the specified channels for 2-wire or 4-wire RTD measurements and immediately sweep through the scan list one time. Use “85” to specify α = 0.00385 or “91” to specify α = 0.00391. bz vv

v yz“z xv	. The readings are sent directly to the
instrument’s output buffer but the readings vz		stored in reading

memory. The default (DEF) type is “85” (α = 0.00385).

For 4-wire RTD measurements (FRTD), the instrument automatically pairs channel with channel 87 (34901A) or D (34902A) to provide the source and sense connections. For example, make the xz connections to the HI and LO terminals on channel 2 and the z connections to the HI and LO terminals on channel 12. Specify the

paired channel in the lower bank (source) as the vt		channel.
MEASure:TEMPerature?
{THERmistor},{2252500010000DEF}
[,1[,<	>MINMAXDEF}]] ,(@<	>)

Configure the specified channels for thermistor measurements and immediately sweep through the scan list one time. bz vv

v yz“z xv	. The readings are sent directly to the
instrument’s output buffer but the readings vz		stored in reading
memory. The default (DEF) transducer type is a 5 kΩ thermistor.
MEASure:VOLTage:DC?
MEASure:VOLTage:AC?
[{<”z	>AUTOMINMAXDEF}
[,<	>MINMAXDEF}],] (@<	>)

Configure the specified channels for dc or ac voltage measurements and immediately sweep through the scan list one time. bz vv

v yz“z xv	. The readings are sent directly to the
instrument’s output buffer but the readings vz		stored in reading
memory. For ac measurements, the resolution is actually fixed at
61⁄2 digits; the	parameter only affects the number of digits
shown on the front-panel.
