Compare Enter the Compare setup submenu. Under this menu, states of the four compare
methods, compare parameters can be set.
Measure Enter the Compare function submenu. Under this menu, wave voltage, wave time,
wave frequency can be set.
Utility Enter the Utility function submenu. Under this menu, internal file, wave amplitude,
grid in the waveform display zone, corona display zone, and the state of the key lock can be
set.
Statistics Enter the Statistics function submenu. Under this menu, statistics for the current
test result can be set. User can select to open, clear or save data.
Modify Press the corresponding soft key and revolve the roller to modify the impulse
voltage, sampling rate, etc.
4.3.1 Display
The instrument provides two display mode: multi and single.
4.3.1.1
Multi
If Multi is selected, all the test results of the inserted test steps will be
displayed on the screen below. When all the results of the test steps are
OK, the final result is PASS. Once one of the test step fails, the final
result is FAIL.
4.3.1.2
Single
If Single is selected, the current test result of the selected test step will
be displayed on the screen below, including the comparison result,
corona and peak voltage.
4.3.2 Compare
TH2883 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 6000 points, thus user can select
the comparison area between the start position and 6000.
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 roller. When the roller 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.
