Special Features
top
- Stroboscope with easy to read LED display
- 7 LED illuminants assure a good illumination of the observing object
- 1500 Lux at a distance of 20 cm and 6000 min-1
- Double-flash-function (x 2) and half-rate-flash function (: 2) for easy and fast determination of the true flash rate
- Adjustable flash duration time for best illumination
- e. g. shorter flash period = tighter image
- e. g. longer flash period = more brightening - Adjustable delay time of internal trigger signal and flash for optimal monitoring of motion sequences
- Protection class IP65 (splash water and dust protection)
- Battery operated
Additonal function: Modesl DSL-300-T with trigger input and output
- External trigger signal
- Adjustable delay time in ms between external trigger input signal and flash for optimal
monitoring e. g. clock frequency or starting period of a machine
- Phase shift between trigger signal and flash to make a rotating part visible in
different degrees
- Pulse divider to determine which input pulse should be used as signal for the flash
Standard Features
- Selectable units Hz, min-1 or FPM
- One hand use
- Handy, shock protected housing
- Calibration report of manufacturers optional available
