9.0 SPECIFICATIONS 1.0 OVERVIEW Internal Mode: The Nova-Strobe vbx is a truly portable, battery-operated stroboscope Flash Range 30 - 50,000 FPM (Flashes Per Minute) that is suited for a wide range of industrial, institutional, and educational 0.004% of setting or ± last digit Flash Rate Accuracy applications, and is able to interface with several of the Vibration Data Flash Rate Resolution...
All applications suited to a general purpose, phase shifting When charging, the strobe will indicate CHRGE in the bottom right of the stroboscope (Nova-Strobe pbx) display. The recharger will fast charge the batteries for about 4-5 hours and then trickle charge the batteries. The Nova-Strobe vbx can also be used as a highly accurate, remote electronic digital tachometer for direct measurement of RPM/RPS (speed) without Allow the recharger to charge the batteries until the display shows...

In Internal Mode, toggles between normal flash rate adjust CAUTION: Do NOT allow the reflector to contact the lamp. and “phase” delay adjust Reinstall the reflector and then position the front lens in place In External and Lock Modes, cycles through External only matching up the notches on the lens with the two small tabs on (no delay), Phase, Time and Auto (VRPM) the housing to prevent lens rotation (see Figure 4).

The input and output are TTL compatible. See Figures 2 and 3 for To change the lamp: connector connection detail. Push apart the two tabs on the side of the reflector housing and remove the lens using a small screwdriver to help pry one tab and Common lift the lens.
NOTE: When using external sensors that are powered by the Nova- when using a delayed flash mode. The Nova-Strobe vbx has an “Input Blanking” Strobe vbx, e.g. Remote Optical Sensor (ROS-P), the sensor feature to allow it to ignore this false trigger. must be plugged in before the stroboscope is turned on, or Even with the Input Blanking, large delays cannot be obtained using an ROS the remote sensor may not be powered up.
For these tests the strobe light should be set on a tripod. A long cable Once the desired menu option is displayed, press the MENU button will be needed for the sensor. The sensor should be mounted on a again to select/save it. Press any other button to cancel selection. magnetic base.
In the Internal Mode the knob adjusts the flash rate. In the External to an area above any split line, to the bearing cap. Note the phase Input Mode an external signal is used to trigger the flash and the knob has angle at each of these locations.
