• Remote Interface Operation: You can use the following commands to
make min-max measurements.
CALCulate:FUNCtion AVERage
CALCulate:STATe {OFF|ON}
CALCulate:AVERage:MINimum? read the minimum value
CALCulate:AVERage:MAXimum? read the maximum value
CALCulate:AVERage:AVERage? read the average of all readings
CALCulate:AVERage:COUNt? read the count
A new command is available starting with firmware Revision 2 which
allows you to take readings using INITiate without storing them in
internal memory. This command may be useful with the min-max
operation since it allows you to determine the average of a series of
readings without storing the individual values.
DATA:FEED RDG_STORE, "" do not store readings
DATA:FEED RDG_STORE, "CALCulate" store readings (default)
See page 126 for more information on using the DATA:FEED command.
Null (Relative) Operation
When making null measurements, also called relative, each reading
is the difference between a stored null value and the input signal.
One possible application is in making more accurate two-wire ohms
measurements by nulling the test lead resistance.
Result = reading – null value
Applies to all measurement functions, except continuity, diode, and ratio.
• The null value is adjustable and you can set it to any value between
0 and ±120% of the highest range, for the present function.
• The null value is stored in volatile memory; the value is cleared
when power has been off, after a remote interface reset, or after a
function change.
