The HHT digital stroboscopes
provides reliable and accurate
speed measurements as well as
stop-motion diagnostic inspection.
A rotary encoder enables quick,
precise frequency setting from
30 to 20,000 flashes per minute. The
crystal-controlled circuitry eliminates
drift and allows readings accurate
to 0.1 rpm. "Divide by 2" and
"Multiply by 2" buttons let the user
check actual rpm. With "Phase +"
and "Phase -" buttons, the user can
add or subtract internal phase
delays to keep the reference viewing
target in eyesight. An "Adder Mode"
enables visual inspection for
misalignment or bent odd-numbered
fan blades, propellers, etc. In the
"Tach" mode, the unit uses external
sensors to measure up to 250,000 rpm
directly without flashing the strobe.
Up to 6 preset memory values can
be recalled from memory, and the
unit recalls the last value measured.
A "Charge" indicator shows
remaining battery life. The
microprocessor-controlled charging
circuit ensures long battery life.
