4.3 Introduction to soft keys in measurement display page
Standard Enter the Standard sampling sub-menu. Under this menu, standard sampling method, standard
sampling, etc. can be selected.
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 Standard sampling
The instrument provides three sampling modes: manual, auto and loop.
4.3.1.1
Manual
Start to sample a standard waveform. When finished, standard waveform
will be displayed in the waveform display zone.
Complete
Press this key to complete the acquisition of standard waveforms.
Average 1
Indicate the sampling times for standard waveform.
Undo
Cancel the current acquisition data for standard waveform. Each press of this soft key
will reduce the sampling average times by 1. This key is available when Average is
larger than 1.
Undo All
Cancel all acquisition data for standard waveform. This key is available when Average
is larger than 1.
Start
Start to collect data for standard sample wave. Averaging can be taken after multiple
sample data is collected for several times.

4.3.1.2
AUTO
At each frequency, the instrument automatically samples a standard wave on the
sample. Finally, a wave at an appropriate frequency will be selected.
Display sample waveforms at lower frequencies.
Display sample waveforms at higher frequencies.
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 error information will prompt and the instrument will keep
in the wait state to Start a new sample.
Start
Start automatic test.
