FREQ
Frequency. Instructs the multimeter to measure the frequency of the input signal.
You must specify whether the input signal is AC voltage, AC+DC voltage, AC
current, or AC+DC current using the FSOURCE command.
Syntax
FREQ [max._input][,%_resolution]
max._input
Selects a fixed range or the autorange mode. The ranges correspond to the type
of input signal specified in the FSOURCE command. That is, if ACV is the specified
input signal, the max._input parameter specifies an AC voltage measurement
range. To select a fixed range, you specify max._input as the absolute value (no
negative numbers) of the expected peak value of the input signal. The multimeter
then selects the proper range. Refer to the
showing the ranges available for each type of input signal.
To select the autorange mode, specify AUTO for max._input or default the
parameter. In the autorange mode, the multimeter samples the input signal
before each frequency reading and selects the proper range.
Power-on max._input = not applicable.
Default max._input = AUTO.
%_resolution
The %_resolution parameter specifies the digits of resolution and the gate time as
shown below (%_resolution also affects the reading rate, refer to the
