Metering Keys
Metering keys control the metering functions of the electronic load. As set from the factory, all front panel measurements are calculated from a total of 1000 readings taken at a 10 microsecond sampling rate. Therefore, the factory default acquisition time for a single front panel measurement is about 10 milliseconds. Refer to “Making Front Panel Measurements” for more information about changing the front panel sampling rate and the number of measurement points.
Meter
Takes the front panel back to the Metering mode from any other mode.
Also accesses the meter menu. This menu lets you measure various parameters of the selected input.
