LOOP
The instrument starts to sample standard waveforms, change frequency,
and cycle sampling.
Select
Select the sample waveform at the current frequency as the standard
waveform.
Select & Check Compare the sample wave with the standard wave at the
current frequency, if the compare result is within the error
range, choose the sample wave at the current frequency as
the standard wave and return to the main menu; if the
compare
result
is
beyond
the
error
range,
an

information will prompt and the instrument will keep in the
wait state to Start a new sample.

Return to the main menu.
Compare
PT50xx series provides four kinds of compare methods as follows: Area Size Comparison,
Differential Area Comparison, Corona Discharge Comparison and Phase Differential
Comparison. The instrument collects the waveform data of 6500 points, thus user can select
the comparison area between the start position and 6500.
Press the Compare soft key to enter the main menu of it. Four compare methods can be set
under this menu.
Note: Press the soft key to enable the number . When the left/right key is
revolved, two parallel yellow lines (except Differential Phase comparison) will be
displayed in the waveform display zone. The full line is the selected one, while the dash
line is not the selected one.
4.3.2.1
AREA SIZE
Select the area comparison method.
State
means this method is turned on, while
means off.
Lighten this icon to enable the left/right key. The start point, the
end point or both the start and the end points will be selected by
the press of the cursor key. Pressing cursor key 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 6500.
