Measurement Computing ZonicBook 618E rev.3.4 - Manual (Page 66)

Configuration
All configurations pertaining to tachometers are controlled by eZ-Analyst or eZ-TOMAS software. There
are no physical jumpers or switches to set in hardware.
You can use eZ-Analyst or eZ-TOMAS to select AC or DC coupling, tach mode, trigger configuration, and
other configuration parameters.
¾ Tach Channel support is only available with eZ-Analyst and eZ-TOMAS
software.
¾ To determine trigger voltage, the Tach Channel must be set to voltage mode.
Reference Notes:
For detailed documentation regarding software you will need to refer to one or more of the
following, as applicable. A PDF version of each is included on the installation CD.

Tachometer Setup
Review the setup and operating instructions for your specific tachometer for details
and pay strict attention to all Warnings and Cautions.
After setting up the tachometer, connect its signal line to one of the four tachometer BNC connectors located
on ZonicBook/618E’s front panel. These connectors are labeled TACH1, TACH2, TACH3, and TACH4.
Tachometers connected to these BNCs can make use of Counter, Period, or Voltage modes. Alternatively, a
tachometer can be connected to a main analog input channel [these are labeled CH1 through CH8].
When a tachometer is connected to one of the analog input channels (CH1 through CH8) the tachometer’s use
is limited to Voltage Mode.
To check the phase relationship between a vibration sensor and a tachometer select Counter Mode if the
tachometer is connected to one of the Tach Input BNCs (TACH1 through TACH4). Select Voltage Mode if
the tachometer is connected to one of the direct analog input channels (CH1 through CH8).
In regard to viewing readings from ZonicBook/618E, refer to the applicable software documentation, e.g.,
eZ-Analyst or eZ-TOMAS.
