Flash Rate: 30 to 32,500 flashes per minute (FPM) with "direct digital synthesis" providing an "analog feel" adjustment knob with precise digital resolution. Adjustments may be made in steps of .1, 1, 10, 100 or 1000 to 32,500 FPM
Flash rate is displayed with an accuracy and a resolution better than 0.01%
Microprocessor control provides versatility never before obtainable in a stroboscope including:
Dual function delays in the external mode with delays adjustable as phase angle or time with auto switch-between
"Direct digital synthesis" provides delay resolution to 0.10 and 0.0001 seconds. The external input accommodates signals from TTL to 24V. Excitation is directly provided to power optical, proximity and magnetic sensors. A TTL compatible output pulse provides drive to slave units or recording equipment
Operates from internal rechargeable batteries and line power
Total portability with internal rechargeable batteries; only 2.5lb
Continuous cool operation
Memory and Auto-Step operating modes
More than 20% brighter, white light on the subject
Alphanumeric LCD shows flash rate in flashes per second or flashes per minute and delays in degrees or milliseconds
Single buttons for instant flash rate change to twice (x2) or half (÷2) current flash rate setting for absolute speed determination
