[. . . ] With no input signal applied, period measurements return "0". The range and resolution are fixed for continuity tests (1 k range and 51/2 digits). The range and resolution are fixed for diode tests (1 Vdc range with 1 mA current source output and 51/2 digits). 118 Chapter 4 Remote Interface Reference The MEASure?and CONFigure Commands CONFigure:VOLTage:DC {<range>|MIN|MAX|DEF}, {<resolution>|MIN|MAX|DEF} Preset and configure the multimeter for dc voltage measurements with the specified range and resolution. CONFigure:VOLTage:DC:RATio {<range>|MIN|MAX|DEF}, {<resolution>|MIN|MAX|DEF} Preset and configure the multimeter for dc:dc ratio measurements with the specified range and resolution. For ratio measurements, the specified range applies to the signal connected to the Input terminals. Autoranging is automatically selected for reference voltage measurements on the Sense terminals. CONFigure:VOLTage:AC {<range>|MIN|MAX|DEF}, {<resolution>|MIN|MAX|DEF} Preset and configure the multimeter for ac voltage measurements with the specified range and resolution. CONFigure:CURRent:DC {<range>|MIN|MAX|DEF}, {<resolution>|MIN|MAX|DEF} Preset and configure the multimeter for dc current measurements with the specified range and resolution. CONFigure:CURRent:AC {<range>|MIN|MAX|DEF}, {<resolution>|MIN|MAX|DEF} Preset and configure the multimeter for ac current measurements with the specified range and resolution. CONFigure:RESistance {<range>|MIN|MAX|DEF}, {<resolution>|MIN|MAX|DEF} Preset and configure the multimeter for 2-wire ohms measurements with the specified range and resolution. CONFigure:FRESistance {<range>|MIN|MAX|DEF}, {<resolution>|MIN|MAX|DEF} Preset and configure the multimeter for 4-wire ohms measurements with the specified range and resolution. This command does not initiate the measurement. 4 119 Chapter 4 Remote Interface Reference The MEASure?and CONFigure Commands CONFigure:FREQuency {<range>|MIN|MAX|DEF}, {<resolution>|MIN|MAX|DEF} Preset and configure a frequency measurement with the specified range and resolution. For frequency measurements, the multimeter uses one "range" for all inputs between 3 Hz and 300 kHz. With no input signal applied, frequency measurements return "0". CONFigure:PERiod {<range>|MIN|MAX|DEF}, {<resolution>|MIN|MAX|DEF} Preset and configure a period measurement with the specified range and resolution. For period measurements, the multimeter uses one "range" for all inputs between 0. 33 seconds and 3. 3 µsec. With no input signal applied, period measurements return "0". CONFigure:CONTinuity Preset and configure the multimeter for continuity measurements. The range and resolution are fixed for continuity tests (1 k range and 51/2 digits). CONFigure:DIODe Preset and configure the multimeter for diode measurements. [. . . ] For the Agilent 34401A, these functions are specified to measure down to 1% of the selected range. For example, the multimeter can measure down to 1 mV on the 100 mV range. 226 Chapter 8 Specifications Interpreting Multimeter Specifications Resolution Resolution is the numeric ratio of the maximum displayed value divided by the minimum displayed value on a selected range. Resolution is often expressed in percent, parts-per-million (ppm), counts, or bits. For example, a 61/2-digit multimeter with 20% overrange capability can display a measurement with up to 1, 200, 000 counts of resolution. [. . . ]
