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
selected by the press of the roller. Then revolve the roller to change
the position of the high and the low limits. The differential value
between the high and the low limits (Δs) is as shown on the second
soft key.

The high limit, the low limit or the high and the low limits can be
selected by the press of the roller. Then revolve the roller to change
the position of the high and the low limits. The differential value
between the high and the low limits (ΔHz) is as shown on the second

 Scale Lighten the icon and enable the roller. Then revolve the roller to enlarge the
waveform display scale ranging from 1 to 3 times. When the display scale is
larger than 1 times, the ratio will be displayed in the top right corner of the
waveform display zone.
 Grid  means the grid is turned on, while  is off.
 2nd  means the corona is turned on. The secondary display zone will display
the quantity of the extracted corona.
 means the corona is turned off. The secondary display zone will display
basic test parameters of the standard waveform and the comparison
methods.
 Key This soft key is used to lock the keyboard. When the function is enabled, the
icon  will be displayed in the information zone. This soft key is also the
Unlock key.
