Figure 186: New Test Wizard – Selecting Tachometer channels (7.5 Hardware and
above)
In 7.5 hardware unit(s), tachometer/output channels can be selected as the
dedicated tachometer channels. The user can turn Tachometer Channel 2 ON or
Turn OFF, depending on the specific user requirement. The Reference
tachometer is always Output Channel 1 or Tachometer Channel 1. Tachometer
Channel 2 (Output Channel 2) can only be used to calculate RPM and does not
support Order analysis functions in any other way.
In the 7.4 hardware unit(s), output channels are not capable of performing the
tachometer measurements, so one or two of the input channels must be
designated as a tachometer channels. The choice of selection of the tachometer
channels can be made by the user. Any input channel of the master module (only)
may be used.
Figure 187: New Test Wizard – Selecting Tachometer channels (7.4Hardware and
below)
User must have at least one tachometer channel enabled to perform the order
tracking functions. Use of the second tachometer is optional.
One of the tachometer channels (when tachometers are selected) must be used as
a reference tachometer in order to perform the order analysis. User has the choice
to select one of the two tachometers as the Reference Tachometer.
