How to count
Enter the counting mode by pressing on the counting function-key. A small frame will
appear on the display. By pressing the up and down arrows the size of the frame will
change. Position the corona image in the center of the frame and wait until the count
value stabilizes with only small fluctuations.
To count accurately
1)
Set the UV gain default to the lower value recommended by the manufacturer,
as appears in your supplied instruction manual.
2)
Verify that the camera operates at normal video rate – LI0
(no long integration)
in the status line.
3)
Set the camera to manual focus and defocus. By defocusing the camera will
count UV spots that were overlapping in the focused mode and were counted
as a single
spot.
4)
The displayed
counting is an
average of the
last 4 display
values, it is
therefore
necessary to wait 4 successive displays, about 25 sec.
Compare counting
Counting can be used as a comparative tool. When comparing counting, it is
important to compare just the reading but keep all other variables that affect
counting such as distance, angle, same camera, and same ambient conditions –
equal.
(*)
The camera is not sold as an electrical measuring device and its output does not read directly the pC value of a corona
Exposure
The visible camera, by default, is set to automatic exposure mode.
Under certain light conditions details like cables may be invisible and changing
manually the exposure might help. The exposure affects the recorded video clips and is
a function of the visible channel only.
