(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
Turn on the strobe. 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.
Clearing All Memory
Turn off the strobe. Press and hold the MODE
key, and then press the power switch . SEL
is displayed. Press and hold
MODE , then press
MEMORY to display CLr. Press MEMORY again
and stored memory is cleared (CLr disappears
in three seconds). After memory is cleared
the strobe returns to default measuring mode
(3,000 FPM).
MEASURING
1. Visually note a unique feature on the
object to be measured or physically
mark it with reflective tape or chalk.
2. Press to turn on the strobe. The
LED indicator blinks and the strobe
flashes at 3,000 FPM factory default
or previous power down value.
3. Set flash rate to maximum and aim
at the object. Press the ▼ arrow until
the object appears frozen. To find true
rpm, press the
÷2 button, ▲ or ▼
arrows, to adjust the flash rate until
the first time a single mark appears.
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. While the 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.
4. Press to turn off the strobe (the display remains for two more
minutes). The strobe shuts off automatically after 10 minutes.
