•For the range parameter, MIN selects the lowest range for the selected function; MAX selects the highest range; DEF selects autoranging.

•For the resolution parameter, specify the resolution in the same units as the measurement function, not in number of digits. MIN selects the smallest value accepted, which gives the best resolution; MAX selects

the largest value accepted, which gives the least resolution;

DEF selects the default resolution which is 51⁄2 digits slow (10 PLC).

Note: You must specify a range to use the resolution parameter.

MEASure:VOLTage:DC? {<range>MINMAXDEF},{<resolution>MINMAXDEF} Preset and make a dc voltage measurement with the specified range and resolution. The reading is sent to the output buffer.

MEASure:VOLTage:DC:RATio? {<range>MINMAXDEF},{<resolution>MINMAXDEF} Preset and make a dc:dc ratio measurement with the specified range and resolution. The reading is sent to the output buffer. 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.

MEASure:VOLTage:AC? {<range>MINMAXDEF},{<resolution>MINMAXDEF} Preset and make an ac voltage measurement with the specified range and resolution. The reading is sent to the output buffer. For ac measurements, resolution is actually fixed at 61⁄2 digits. The resolution parameter only affects the front-panel display.

MEASure:CURRent:DC? {<range>MINMAXDEF},{<resolution>MINMAXDEF} Preset and make a dc current measurement with the specified range and resolution. The reading is sent to the output buffer.
