parameters Description
4. MENU
rpm / Hz / FPM Unit of frequency selection:
– rpm: unit for measuring
rotational speed
– Hz: lash frequency per second
– FPM: lashes per minute
6. MENU MULT:
x 1, x 2, x 3, ... /
÷1, ÷2, ÷3, …
respectively.
The selected
lash frequency
is immediately
multiplied/
divided by
1, 2, 3... Multiplier:
– This function is only possible
when the “internal trigger” is
selected.
Multiplier (MULT.)
At this function the adjusted frequency can be divided or multiplied with integer values to check the harmonic multiple
images (
† section 9
–
“Determining the actual rotational speed of an object” ).
1. MENU BRIGHT:
PULSE deg /
PULSE μs Selection of brightness unit (in
degrees or microseconds).
Brightness (BRIGHT in deg / BRIGHT in μs)
Flash duration. This function allows the lash duration to be adjusted, which inluences the brightness and focus
of the object being viewed. Brightness can either be measured in absolute terms (microseconds) or in relative
terms (degrees).
2. MENU DELAY ms:
0 … 2,0 Delay time setting (in
milliseconds) between the trigger
signal and lash.
Position ixed; actual delay
depending on current frequency.
7. MENU DIV:
1 … 255 Pulse divider,
max. value 255
– This function is only possible
when the “external trigger” is
selected.
Pulse divider (DIV)
The pulse divider can be used to set a value x, by which the external trigger signal is then divided.
Example: when scanning a cog wheel, an external trigger (e.g. rotational speed sensor) sends out a signal for each cog
scanned. With a DIV value of 10, it will only lash once in every 10 signals.
