Counter-clockwise: Decrease

Forsmalladjustments,turnthedialslowly.For largeadjustments,rotatethedialquickly.

Theflashrate and resolutiondiffersaccordingtomeasuringrange.Refertosection4.5.1fordetails.

Notesforsettingtheflash rate

One function of a stroboscope is to provide a “Frozen” virtual image of a rotating target once the flash rate

of the stroboscope matches the rotational speed of the target object (FPM=RPM). The stroboscope will

also show a single image when the flash rate or frequencyis set to a lesser multiple of the RPM (1/2, 1/3,

etc.) Whenthe flashrateis increased toahighmultiple (2,3,etc.),multiple images will appear.Tofind the

true RPM of the target object, begin by lowering the FPM to lower multiples until only a single image

appears.Formoreinformationregardingthemultiply/divide by2 function, pleasesee4.3.5.

1) Doublingtheflashrate(x2)

Press“x2”keytomultiplythecurrentflashrate byafactor 2untilthemaxflashrateis reached.

Operation Indication

Pressandrelease

Aftertheflash rate(frequency) changes,it becomesthe new value based ontheset displayresolution. (See

section 5. Specifications) Therefore, the frequency is not to return to the original frequency, even if “½”key is

pressedafterpressing“x2”key.

2) Halvingtheflashrate(½)

Press “½” keyto dividethecurrentflashrate by a factor of 2untiltheminflashrate isreached.

Operation Indication

Pressandrelease

After the flash rate (frequency) changes, it becomes the value based on the set display resolution. (See

section 5. Specifications) Therefore, the frequency is likely not to return to the original frequency even if

“x2”keyispressedafterpressing“½”key.
