2.4 TACHOMETER
First tab: Tachometer setup
 Adjustment of tachometer parameters:
o Input range: select the range according to the tachometer signal : +/-10V, 0/-24V, 0/+24V
o Coupling:
 DC: default setting
 AC: a 0.3Hz high-pass filter is applied. This can be used if the DC component of the signal
is changing during measurement (for example: signal from a proximity probe during run-up
/ coast-down). If AC coupling is selected the automatic setup function is not accessible.
o Trigger slope: - (trigger on negative slope) or + (trigger on positive slope)
o Trigger threshold: value in Volt triggering the tacho input. It must be between -24 and +24 and
within the selected input range.
o Hysteresis: value in Volt above (if slope=-) or under (if slope=+) trigger threshold to rearm the
system for the next triggering.
 Functions:
o Auto setup: function to automatically adjust the trigger threshold and hysteresis. This function
is not accessible if Coupling = AC.
o Test: when using this function, the power supply of the sensor is switched on. If the setting is
correct, you have green indicator , you must read a correct value of the rotation speed.
Second tab: display the signal. In case of difficult setting, it will help you adjust the parameters and check the
tachometer signal.
 Select first the duration in the list according the range of rotation speed.
 See signal: when using this function, the power supply of the sensor is switched on and the signal is
displayed.
From both tabs, to store the new setting exit with the function “Save” . “Cancel” exit with no setting
change.
2.5 SPECTRUM DISPLAY
Set the amplitude type, unit of spectrum and rotation speed:
 Spectrum amplitude: Linear, Exponential, dB
 Frequency and rotation speed unit: Hz, CPM, Order
Note: if ‘Order’ is selected, it is necessary to have machine rotation speed different from 0. In this case,
spectrum frequency axis is expressed in Hz.
 Acceleration, Velocity, Absolute displacement or Relative displacement amplitude: RMS, Peak or Peak-to-Peak.
Select the amplitude type displayed in the spectra for each type of magnitude.
 Acceleration, Velocity, Absolute displacement or Relative displacement unit: select the amplitude unit displayed
in the spectra for each type of magnitude.
 Spectrum conversion: None or converted to Acceleration, Velocity or Displacement. This setting is used in the
Collect module.
 Envelope conversion: None or converted to Acceleration, Velocity or Displacement This setting is used in the
Collect module.
 Hide 0Hz envelope spectrum: select Yes to hide the 0Hz for envelope spectrum. This is necessary mainly with
a linear scale as the 0Hz line amplitude is usually greater than the other ones.
