The MEASure? and CONFigure Commands

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

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

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. Note that this command also redefines the scan list. The readings are sent directly to the instrument’s output buffer but the readings are not stored in reading memory. The default (DEF) type is “85” (α = 0.00385).

For 4-wire RTD measurements (FRTD), the instrument automatically pairs channel n with channel n+10 (34901A) or n+8 (34902A) to provide the source and sense connections. For example, make the source connections to the HI and LO terminals on channel 2 and the sense connections to the HI and LO terminals on channel 12. Specify the paired channel in the lower bank (source) as the scan_list channel.

MEASure:TEMPerature? {THERmistor},{2252500010000DEF}

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

Configure the specified channels for thermistor measurements and immediately sweep through the scan list one time. Note that this command also redefines the scan list. The readings are sent directly to the instrument’s output buffer but the readings are not stored in reading memory. The default (DEF) transducer type is a 5 kΩ thermistor.

MEASure:VOLTage:DC?MEASure:VOLTage:AC?[{<range>AUTOMINMAXDEF}

[,<resolution>MINMAXDEF}],] (@<scan_list>)

Configure the specified channels for dc or ac voltage measurements and immediately sweep through the scan list one time. Note that this command also redefines the scan list. The readings are sent directly to the instrument’s output buffer but the readings are not stored in reading memory. For ac measurements, the resolution is actually fixed at

61⁄2 digits; the resolution parameter only affects the number of digits shown on the front-panel.
