Standard Mode NOTE: Not all of the setting shown in Fig 2 are available in Standard Mode. Position of the Adjustable Description Selector Switch Parameters — Device is switched off FREQUENCY Frequency selection; FPM: flashes per minute - Turning the knob while pushing it simultaneously, the adjustment increment is effected in steps of 100. - Page 9 Position of the Adjustable Description Display Selector Switch Parameters MENU PHASE deg: Delay setting between the trigger signal 0…359 and flash (in degrees relative to the frequency Phase sift (PHASE in deg) Phase shift setting (in degrees, relative to the frequency) between the trigger signal and flash. This value allows a fixed angle to be set between the trigger signal and flash.

Pro Mode Follow the steps below to access the pro mode: 1. Turn the selector switch (E) from OFF to the required position while simultaneously holding the rotary/push knob (D) until the PRO notification appears in the display. 2. When the Pro mode is activated, a P appears in the bottom right area of the display NOTE: If you have selected settings in Pro Mode and then switch the device off, these settings will ONLY be active when the device is switch back on if pro mode is activated. - Page 12 Position of the Adjustable Description Display Selector Switch Parameters MENU rpm / Hz / Unit of frequency selection: - rpm: unit for measuring rotational speed - Hz: flash frequency per second - FPM: flashes per minute Multiplier: MENU MULT: x1, x2, This function is only possible when the x3…/ +1, internal trigger is selected...

Page 16: Determining An Object's Actual Rotational Speeds
5.0 DETERMINING THE ROTATIONAL SPEED OF OBJECTS The stroboscope can be used as a digital revolution indicator to determine an object’s actual rotational speed and/or the frequency of cyclical movements. The stroboscope does this by visually “freezing” the object’s movement and then taking a reading of the rotational speed or frequency from the LCD display. - Page 17 Which is correct? To determine the fan’s actual rotational speed, one of the ventilator vanes is attached with a marking and the test is repeated. The orientation marking confirms that the images at 3,300, 1,650 and 825 rpm are harmonic multiple images.
