Front Panel Operation - 5

Metering Keys
Metering keys control the metering functions of the dc source. As set from the factory, all front panel
measurements from the main output (output 1), are calculated from a total of 2048 readings taken at a
46.8 microsecond sampling rate. Therefore, the factory default acquisition time for a single front panel
measurement is about 100 milliseconds. Refer to “Making Front Panel Measurements” for more
information about changing the front panel sampling rate and the number of measurement points.
All front panel measurements from the DVM and from output2 are fixed at 2048 measurement readings
taken at a 15.6 microsecond sampling rate.
NOTE: The front panel sample rate and data point settings are separate and independent of the
sample rate and data point settings that are programmed over the GPIB interface. When
an GPIB measurement is in progress, the front panel display temporarily indicates
-- -- -- -- --. Front panel measurements resume when the GPIB measurement completes.
