4.5 Energy Measurement
4.5.1. Setup
Switch the Vega on. If it is in power mode, press the left
soft key “Energy” to put it into energy mode.
The energy mode is manual ranging: enter “Range” and
then use the navigation keys to get to the proper range
then enter again. The correct range is the lowest one
which is larger than the pulse energy measured. If you
plan to use the same setting often, use the "Configure"
function as described in Section 4.3 before switching the
Vega off the first time. When the Vega is switched on
again, it will automatically go into the same range until a
different configuration is saved.
Note:
The present range is displayed on the upper left and
bottom right of the energy measurement screen as
shown in Figure 4.6.
