Remote transducer
Other types of transducers can be used by switching
the setting of ‘Transducer’ to ‘Remote’ (2).
When using a proximity switch the setting of ‘Trans-
ducer type’ is ‘PNP’ or ‘NPN’ (3). The setting of ‘12V
Supply’ should be ‘ON’ (4).
When Leonova is connected to a stroboscope, the
setting of ‘Transducer type’ (3) is normally set to
‘NPN’. Some types of stroboscopes require the
setting ‘PNP’. The setting of ‘12V Supply’ should be
‘OFF’(4).
When Leonova is connected to a Key Phasor for rpm
measurements, the setting of ‘Transducer type’ is
‘KeyPhasor’.‘12VSupply’(4)shouldbe‘OFF’(4).

the speed via the keyboard window.
Contact measurement
Forcontactmeasurement,youplacethecontact
adapter over the lens and fix a contact centre or
a wheel. The shaft in the adapter has a reflecting
surface, and each revolution sends one light reflex to
the counter. The contact centre is pressed firmly into
the cavity at the centre of the shaft, and the probe is
aligned with the shaft’s centre line.
The wheels are used to measure peripheral speed.
One turn corresponds to 0.1 m, 0.1 yards, or 0.5 feet,
depending on the wheel type.
