Besides technical informations the instructions contain also important hints for use and application as well as special cautions against demage or injury. Please note that we feel not responsible for any kind of demages or defects caused to the instrument by inapprobiate...

Immediately after switch-on the first reading on the LC display indicates the last value measured by the unit before switch-off. Data presentation on display: n/RPM or f/HZ XXXXX XXXXX Now further...

For this purpose the oscillating or rotating object is illuminated in a periodic series of light impulses (flashes) which are as brief as possible. The object then appears (at the appropriate flash frequency) to be motionless (stopped image) or slowed (slow-motion). The object's behavior...

1000_Art.Nr.1038 table.main {} tr.row {} td.cell {} div.block {} div.paragraph {} .font0 { font:9.00pt "Times New Roman", serif; } then the object no longer appears stopped, but has rotated through the angle 2e between two succeeding flashes. If /e/ is sufficiently small the eye perceives a constant slow-motion cycle. Angular speed w', at which the object appears to rotate, is given by: w' = 2 v' = 2 p e = 2 p e 2 p e T (n+e) r nr If we compare this with the true angular speed of the object, we obtain: w' = (e ■*■n)w For e > 0 (i.e. T > Tn and/or f > fn) w and w' have the same sign, so that true...

This is usually the case when the unit shows physical demage, no sign of functioning or stress beyond the tolerable limits. Repair, replacing parts, calibration ect. should be carried out by trained personnel only or preferably return it to the manufacturer for inspection and control. TECHNICAL SPECIFICATIONS...
