Measurement Configuration Commands

function>:RESolution {<resolution>|MINimum|MAXimum}
<
Select the resolution for the specified function (not valid for frequency, period, or
ratio). Specify the resolution in the same units as the measurement function, not
selects the smallest value accepted, which gives
in number of digits. MIN
the most resolution.
MAX
the least resolution. [Stored in volatile memory]
< function>:RESolution? [MINimum|MAXimum]
Query the resolution for the selected function. For frequency or period
measurements, the multimeter returns a resolution setting based upon a 3 Hz
input frequency.
< function>:NPLCycles {0.02|0.2|1|10|100|MINimum|MAXimum}
Select the integration time in number of power line cycles for the present
function (the default is 10 PLC
