3.4.9.4 Statistics Display
The statistics display shows simultaneously extreme, average and standard deviation
measurement values over time to conduct for example pass/fail tests. The display is
easy to operate by the three soft keys: Start, Stop and Reset. The meter switches
automatically in auto-range. The Range and REL∆ will be set out of order.

3.4.9.5 Power dBm Display
The power dBm display features a big 4 digit numerical power reading in logarithmic
representation combined with a smaller 4 digit numerical power reading in Watt. The
display has the same Range and REL∆ functionality than the power Watt display but
no zoom function. When REL∆ is activated the units change from dBm to dB, over or
under-range conditions are displayed by Hi and Lo indicators above the units.
