2.0 OVERVIEW
All descriptions in this manual apply to both the “
Basic
” battery powered (BB) and “
Basic
” A
C
mains powered (BA) digital stroboscopes except where noted. The Nova-Strobe Basic models are sophisticated digital instruments with many features yet remain simple to operate.
The S
trobe’
s internal microprocessor and digital encoder knob ensure precise
settings and measurement. The Strobe “remembers” the previous setting when the power is turned off.
2.1 Direct Digital Synthesis “Direct Digital Synthesis” is the method by which the S
trobe’
s internal microprocessor gener
-
ates all the signals required to set internal flash rates. In analog stroboscopes, these values are adjusted using a single or multiple turn potentiometer (knob), which generally lack sensitivity and tend to drift with time. It is very difficult to set absolute values on analog stroboscopes. The digital strobe synthesizes all signals digitally
, in small, very precise steps.
These signals are
derived from a stable crystal oscillator
.
There is no user calibration or adjustment required to
ensure an accurate reading. These steps are as small as 1 flash per minute. Thus absolute values may be dialed in very easily and accurately
.
The S
trobe’
s adjustment knob is actually a digital
encoder that is connected directly to the microprocessor
.
2.2 Display Panel The display panel consists of a liquid crystal display with six alphanumeric digits, which indicate the flash rate. The battery-powered model will also flash the low battery icon ( ) on the display when the battery is getting low
.
The display will show “LO BA
T” on steady
when the strobe
must
be recharged.
