Checkline NS-600 - Manual (Page 4)

Changing Flash Duration (increasing sharpness)
Flash duration is set at F0, which is suitable
for most applications. However, images can
be sharpened by decreasing flash duration.
After synchronizing the flash rate with the
moving object, press and hold the
MODE
key, then press the ▲ or ▼ arrows to select
levels F0, F1, F2, ... F6. As flash duration
shortens the image gets sharper and less
bright. Longer flash durations are brighter and less sharp.
The display is retained for two minutes after the strobe is powered off. If
turned back on while the display is on, the strobe returns to the flash rate
shown on the display. The strobe powers off after five minutes of non-use.
MEMORY
(FPM and Hz units each have nine separate memory locations)
Saving Flash Rates in Memory
Turn on the strobe and synchronize the
flash rate with the moving object. Press
and hold
MODE , then press MEMORY , a
memory location number appears briefly
and the flash rate is saved to that memory
location. When nine locations have been
saved FUL appears on the display.
Memory Recall
Press MEMORY to enter memory mode and
memory location ‘1’ appears at the top of
the display. Press
MEMORY again to select
another location. If no flash rates are
stored, numbers do not appear.
Changing Memory Values
Select a memory location (see Memory Recall above). The memory icon
indicates the stored flash rate matches the current flash rate. Use the
arrow keys to change the flash rate (the memory icon disappears). To
save the new flash rate, press and hold
MODE , then press MEMORY . The
memory icon reappears and shows that the current flash rate is stored.

MEASURING
1. Visually note a unique feature or physically mark the object to be
measured with reflective tape or a chalk mark.
2. Click the POWER switch and release. The LED indicator blinks and the
strobe flashes at 3,000 FPM (factory default) or previous power down
value. Click to turn off. The strobe automatically shuts off after 10
minutes. Turn on the strobe by clicking and holding the
POWER switch.
If released after two seconds the strobe shuts off.
3. Set flash rate to maximum and aim the NS-600 at the
object. To find true rpm, lower the flash rate until the
first time a single mark appears. Use
▲ or ▼ arrows to
adjust the flash rate until the feature or mark appears
frozen. The flash rate changes more rapidly the longer
the
▲ or ▼ arrow key is held, then resets 1.5 seconds
after it is released.
Advanced users: After releasing the
▲ or ▼ arrow, the
numeric place of the flashing digit indicates the rate of
change. Press the
▲ or ▼ arrows to change the value of
the flashing digit. While a digit is flashing, press the
or
arrows to move the numeric place of the flashing
digit higher or lower. Then press the ▲ or ▼ arrow to
change the flash rate using that increment.
Note: If the flash rate is 1/2 of true rpm, 1/3, 1/4, etc., a single mark also
appears. If the flash rate is 2x true rpm, two marks appear, 3x true rpm,
three marks, 4x, four marks, etc. If the flash rate is 2/3 of true rpm, 2/5, 2/7
etc., two marks appear. And 4/3, 4/5 and 4/7 four marks appear, etc.
Digital Phase Shift (image rotation)
After synchronizing the flash rate with the rotating object, press and
hold the
MODE key while pressing the or arrows to adjust the angle.
When the strobe is turned off, the phase shift setting resets to zero.
