The model DT-2239A is a microprocessor circuit design, high accuracy, digital readout, light duty
STROBOSCOPE/TACHOMETER that is ideal for inspecting and measuring the speed of moving
gears, fans, centrifuges, pumps, motors and other equipment used in general industrial maintenance,
production, quality control, laboratories and as well as for schools and colleges for demonstrating

Preparation (a) Plug unit into a properly grounded 110V AC, 220V AC or 230V AC outlet.
(b) Turn the power switch to “on” position.
(c) Determine the range switch to “Low” or “High” position.
Checking Speed When checking speed, care must be taken to insure that the strobe is flashing in
unison (one to one) with the object being monitored. A Stroboscope will also
stop motion at 2:1, 3:1, 4:1 et., this is normally referred to as harmonies. To be
sure of unison, turn the dial until two images appear – this will double the actual
speed. Then lower the flashing rate until a single and stationary image appears –
this is the actual true speed.
Checking Motion For motion analysis, simply locate the actual speed as mentioned above and then
turn the dial slowly up or down. This will give a slow motion effect allowing
