5.2.12 Volt Step
Volt Step ranges from 1% to 50%. The step voltage is calculated as following formula:
Step volt = Start Volt * Volt Step. Move the cursor to this zone, following soft keys will be displayed.
They are coarse soft keys used to change Volt Step by a resolution of 10%.
They are fine soft keys used to change Volt Step by a resolution of 1%.
Lighten this key to enable the numerical arrow key. Respectively press 8, 2, 4, 6, the cursor will
move up, down, left and right.
5.2.13 Comparator
The comparator function allows you to set all comparators to ON or OFF. Once the comparator is turned off,
the instrument cannot make any comparisons, but the test wave or the standard wave is also displayed on the
measurement display page. Move the cursor to this zone, following soft keys will be displayed.
ON Turn on the comparator.
OFF Turn off the comparator
Lighten this key to enable the numerical arrow key. Respectively press 8, 2, 4, 6, the cursor will
move up, down, left and right.
5.2.14 Position (AREA SIZE, DIFF ZONE, PHASE DIFF)
Set the comparison ranges for AREA SIZE, DIFF ZONE and CORONA that range from 0 to 6000 (the value
of the end position must be larger than that of the start position.). Use numeric buttons to enter the required
value and press ENTER for confirmation. Move the cursor to this zone, following soft keys will be displayed.
They are coarse adjustment soft keys used to change the value of position by 100.
They are fine adjustment soft keys used to change the value of position by 10.
Lighten this key to enable the numerical arrow key. Respectively press 8, 2, 4, 6, the cursor will
move up, down, left and right.
5.2.15 Position
（
PHASE DIFF
）
Set the zero-crossing position for PHASE DIFF that is to select a zero-crossing position for the comparison of
phase difference. The zero-crossing position ranges from 2 to 99. Use numeric buttons to enter the required
value and press ENTER for confirmation. Move the cursor to this zone, following soft keys will be displayed.
They are fine adjustment soft keys used to change the zero-crossing position by 1 dot.
Lighten this key to enable the numerical arrow key. Respectively press 8, 2, 4, 6, the cursor will
move up, down, left and right.
