Balancing Using the Strobe light
•
Subsequent runs (add trial weight, etc.) will require you to go through the process
of tuning and locking (lock / track rocker to EXT) before taking readings.
If the strobe does not respond to the signal supplied to it by the Microlog, it is possible
that the trigger signal to the strobe is too low. The output level is shown on the screen
as a number from +0 to +10. If the number shown is +0 then no amplification is going
to the strobe.
To increase the signal to the strobe:
•
On the GX, press shift (0 / up arrow) and the up a
rrow button. Each press of the
key will increment the number by one. It is recommended that a level of +5 is set.
You may need to adjust this level during the balance procedure,
especially after attaching the correction weight as the 1X signal
will be significantly lower.
When the strobe is tuned in Internal mode, and then switched to
LOCK
mode, the filter
in the strobe tracks slight changes in speed. If the speed changes too much or too fast,
the strobe loses LOCK / TRACK and stops flashing. It will be
necessary to switch back to
Internal mode and repeat the adjustments. Also, try switching between the Narrow and
Wide Bandwidth LOCK to optimize results. Generally, the Wide Bandwidth will give best
tracking results, and the Narrow Bandwidth will give b
etter stabilization.
