Both the battery-powered Nova-Strobe DBX and AC-powered Nova-Strobe DAX provide a range of 30 to 20,000 flashes per minute and an accuracy of ±0.004% of setting. Flash rates are easily adjusted to fractional RPM by a coarse/fine control knob. Individual TTL compatible input and output jacks are provided for daisy-chaining multiple strobes, triggering from an external source, or providing a trigger signal to external equipment.
Both DBX and DAX models provide internal phase shifting to keep the target precisely in view. In addition, 9 user-programmable memory flash rates for repetitive measurements and storage of the last flash rate measured are included. All models provide x2/÷2 capability for distinguishing actual RPM from harmonic frequencies.
