Lighten this icon to enable the roller. The start point, the end point
or both the start and the end points will be selected by the press of
the roller. Revolve the roller will change the position of the start
point, the end point or both the start and the end points by 10
points. The position ranges from 0 to 6000.
Lighten the icon to enable the roller and change the differential
value.

4.3.2.2
DIFF ZONE
Select the differential area size comparison method. All setup
operations are the same as those of AREA SIZE.
4.3.2.3
CORONA
Select the corona comparison method. All setup operations are the
same as those of AREA SIZE. The corona comparison value has no
unit ranging from 1 to 255.
4.3.2.4
PHASE DIFF
Select the phase differential comparison method. All setup
operations are the same as those of AREA SIZE. But the position
parameter is different, it means to choose the zero-crossing
position and the value ranges from 2 to 99.

4.3.3 Measure
Measurement function is used to measure impulse voltage, time and frequency.
Note: When a function is selected and the roller is enabled, two lines will be displayed
in the waveform display zone. The differential value of the two lines corresponds to the
value showing on the second soft key.
Press the roller to switch between the high limit, the low limit and the
high and low limits. Then revolve the roller to change the position of
the high and the low limits. The voltage differential value between the
high and the low limits (ΔV) is as shown on the second soft key.
Note: The default low limit locates on the center line.
The high limit, the low limit or the high and the low limits can be
