There are two ranges available: High and
Low. The detailed description of the
measurement ranges parameters is given in
Appendix C.
The values of ranges in sound modes depend
on the settings in the Compensation Filer
screen (path: <Menu> / Measurement /
Compensation Filter) and the calibration
factor.
The right-hand screens present the Range for
the Vibration mode and zero calibration factor.
The calibration factor is always added to the
upper range level – see example.
For example, if the calibration factor is equal
to 0.5 dB, the upper range limits will be
increased by 0.5 dB automatically.
5.8 RPM MEASUREMENT SETTINGS – RPM MEASUREMENT
The RPM Measurement position allows to
switch on and set measurements of rotational
speed, measured by tacho probe.
Note: The RPM function is optional and should be unlocked by entering the activation code in the
text editor screen, which is opened during first attempt to open this position. Once unlocked this
option will be ready to use permanently.
To perform the RPM measurement the RPM probe should be connected to the
I/O socket and the RPM position in the RPM Measurement screen should be
switched on.
When you switch the RPM on the instrument automatically switches the
I/O Mode to Digital In (path: <Menu> / Instrument / Multifunction I/O /
I/O Mode) and makes it inactive.
The Pulses/Revolution parameter defines
the number of pulses per one rotation.
Available values are in the range: 1..360.
The Unit parameter defines units of measure.
Two options are available: revolutions per
minute (rpm) and revolutions per second
(rps).
