[. . . ] 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. This command does not initiate the measurement. 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. This command does not initiate the measurement. 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. This command does not initiate the measurement. 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. This command does not initiate the measurement. The range and resolution are fixed for diode tests (1 Vdc range with 1 mA current source output and 51/2 digits). Query the multimeter's present configuration and return a quoted string. 120 Chapter 4 Remote Interface Reference Measurement Configuration Commands Measurement Configuration Commands See also "Measurement Configuration, " starting on page 51 in chapter 3. FUNCtion "<function>" Select a measurement function. The function must be enclosed in quotes in the command string (FUNC "VOLT:DC"). Specify one of the following strings. VOLTage:DC VOLTage:DC:RATio VOLTage:AC CURRent:DC CURRent:AC RESistance (2-wire ohms) FRESistance (4-wire ohms) FREQuency PERiod CONTinuity DIODe FUNCtion?Query the measurement function and return a quoted string. <function>:RANGe {<range>|MINimum|MAXimum} Select the range for the selected function. For frequency and period measurements, ranging applies to the signal's input voltage, not its frequency (use FREQuency:VOLTage or PERiod:VOLTage). [. . . ] This corresponds to about 0. 0001% (1 ppm) of full scale, or 21 bits including the sign bit. All four specifications are equivalent. Accuracy Accuracy is a measure of the "exactness" to which the multimeter's measurement uncertainty can be determined relative to the calibration reference used. Absolute accuracy includes the multimeter's relative accuracy specification plus the known error of the calibration reference relative to national standards (such as the U. S. National Institute of Standards and Technology). [. . . ]
