You find more information on saving measurement data in the section "Saving / reading measurement data". Then press the MODE button repeatedly until the display (top) shows the required display unit. Sequence 1 sequence 2 function RPM REV RPM = Revolutions per minute (contactless) rPm = Revolutions per minute (contact, with cone) rPm M HZ = Frequency (contactless + contact, with cone) M/M = Metres per minute (contact, with cone) HZ In I/M = Inch per minute (contact, with cone) F/M = Feet per minute (contact, with cone) M/M FT Y/M = Yard per minute (contact, with cone) I/M Yd REV = Total number of revolutions (contactless + contact, with cone) M = Total distance in metres (contact, with friction wheel) F/M In = Total distance in inches (contact, with friction wheel) FT = Total distance in feet (contact, with friction wheel) Y/M Yd = Total distance in yards (contact, with friction wheel) The battery should be removed from the device if it is not used for a long period of time to avoid damage through leaking. Leaking or damaged batteries might cause acid burns when in contact with skin, therefore use suitable protective gloves to handle corrupted batteries. Do not leave the battery lying around, as there is risk, that children or pets swallow it. ⷠBatteries must not be dismantled, short-circuited or thrown into fire.

[. . . ] Rotating parts must always come to a complete standstill and must be secured against being switched on again before attaching any reflector strip. The non-reflecting area must always be larger than the reflector strip. a single data set consists of four measurement values (last displayed value of the measurement process , maximum value (MAX) , minimal value (MIN) and average value (AVG). At the end of a measurement process, press the MEM button while pressing and holding the MEAS button. [. . . ]
