Operation, Taking Measurements
A General
a) The Manual R.P.M. Counter remains active as long as the button
is being pressed down (on housing, to the right of the display)
b) During every measurement, the lowest measured value "dn" (for
down), the highest measured value "UP", and the current measured
value "LA" (=last) are automatically recorded.
c) If the selector switch is in the position "PHOTO", the laser is
activated together with the measuring sensor. The diffuse laser
point helps you to measure the r.p.m. at precisely that point which
you have marked with a reflective tag before, when the machine had
been switched off. When the measuring button is released, the laser
is switched off, too.
d) The adapters have long and short slots. Place the respective
adapter (friction wheel for belt speed, the adapter for number of
revs) onto the axle to the limit stop, in such a way that the shearing
pin fits in the short slot.
Warning!
• During contactless measuring the energy con-
sumption will increase with the operation of the
laser. This reduces the operation time considerably.
• With a "housing temperature" of approx. +60°C
and more, the display may get darker, the liquid
crystal becoming "black" so that the display can-
not be seen well any more. The Manual R.P.M.
Counter is not defective. The black colour will
vanish as soon as the temperature falls below
approx. 60°C (cf. technical data, especially opera-
tion temperature range of the measuring instru-
ment).
