Setting the RPM measurements
– RPM
To perform the RPM measurement the RPM probe should be connected to the
I/O
socket. The instrument automatically detects such connection and switches
the
I/O Mode
to
Digital In
(
path: <Menu> / Instrument / Multifunction I/O /
I/O Mode
).
While the tacho is connected the
I/O Mode
position is inactive.
The
RPM Measurement
position enables
the user to programme the measurements
of rotational speed, measured by tacho
probe. The RPM function usually is an
optional function and should be activated
during first attempt to switch it on.
