Setting Range and Resolution Parameters
The MEASure? and CONFigure commands incorporate parameters for setting the
Meter's function, its range, and its resolution. Placing the input signal's expected
amplitude into the range value causes the Meter to select a range appropriate for the
supplied signal amplitude.
Although the frequency and period functions use a single range for all inputs between 3
Hz and 300 kHz, it is necessary to specify a range whenever specifing a resolution setting
for these functions. When specifying resolution, specify it in the units of the function
instead of number of digits. For ac or dc volts, specify the resolution in volts. The
resolution specification for frequency is in hertz.
A range parameter is required when specifying the resolution parameter.

[3] For period measurements, the Meter uses one range for all inputs
between 0.33 seconds, and 3.3 µsec. With no input signal applied,
period measurements return zero.
[4] The range and resolution are fixed for temperature measurements.
However, placing PT100_385 or PT100_392 into the range field will
set the RTD type. Placing CUST1 into the range field will cause the
Meter to use the values set into the R
[5] The range and resolution are fixed for diode test: 1 Vdc range and 5½
digits. When set to ON, the low current parameter sets the diode test
current to 0.1 mA. When OFF, the current is 1 mA. When set to ON,
the high voltage parameter sets the diode test voltage to 10 volts. When
OFF, the voltage is 5 volts. To specify a diode test voltage, you must
also include ON or OFF for the low current parameter.
[6] The range and resolution are fixed for continuity tests: 1 kΩ range and
5½ digits.
