Temperature measurement
The SPM laser tachometer/IR temperature probe
TTP10 is used for temperature measurements in
the range of –20 to +300 °C (–4 to +572 °F). Meas -
uring accuracy is ± 2.5° C.
The probe has an infrared sensor that allows you
to accurately measure the temperature of a surface
without having to come in contact with it.
The probe is connected via the spiral cable to the
RPM input on Leonova. It is power supplied by the
instrument.
Keep the protective adapter on the probe when
the probe is not used.
To measure, move the laser point so that it is on
the area to be measured and press the M/S key.
Make sure that the target is larger than the unit’s
spot size. The smaller the target, the closer you
should be to it.
Caution: Never point the sighting laser in some-
body’s eye.
The laser tachometer/ IR temperature probe has
distance to spot size (D/S) 8:1, meaning that if the
probe is 800 mm from the target, the diameter of
the object must be at least 100 mm (see the dia-
gram beside). When accuracy is critical, make sure
the target is at least twice as large as the spot size.
