Specifications - Installation and Operating Instructions
I
MODEL TAC·L Portable Digita
l
Tachometer measures rotational speed either by
contact
i
ng a rotatable head to the shan of the object, or using photo sensor to detect
the reflections from the
l
aser
.
The laser target can record from a distance of up to 20
inches and gives a more accurate measurement than LED targeting. Model TAC-L
inc
l
udes a large LCD with a backlight for use in dark areas. This tachOmeter is made
of a strong, lightweight ABS plastic hous
i
ng, which is designed to comfortably fit in the
hand of the user. Supp
l
ied with this model are 3 contact rotational heads, a contact
surface wheel
,
and a protective carrying case

3. Depress the measuring button and align the visible light beam with the applied
target Verify that the mon

In the case of measuring low RPM va
l
ues with the non-contact
laser. it is suggested that the user attach more reflective marks
an average distance apart on the ob
j
ect
,
then measure as above, giVing a more
accurate measurement. The user then must d
i
v
i
de the reading shown by the number
of reflective marks to find the true RPM.
