CoCo-80 Quick Reference
65
Window Type: Hanning, flattop, and uniform. Most
measurements will use the Hanning window.
Overlap Rate: specifies how much of two sequential
blocks will overlap.
Expected RPM: Specifies the expected RPM when
measuring vibration in rotating machinery.
The Input Channels setup specifies the sensor type,
engineering unit (volts, g’s, etc.), sensitivity, and input
mode. To access the channel setup, press F2 (Param.) and
select Input Channels. This will display the sensor status
window, press F1 (Edit Table) to access the sensor setup
table.
The input mode for a sensor is an important parameter to
set. Most accelerometers will need to be set to IEPE,
which enables a current source to power the
accelerometer.

IEPE
The CoCo can also provide an output signal, which can be
set by selecting Output Channel from the F2 (Param.)
