3.2.2
Intelligent Fixture: Rotary/Linear Fixture Position
To access this page, select the Setup icon, then Data, and then
Fixture Position. Either Rotary Position or Linear Position will
appear. Select the appropriate option.
The Intelligent Fixture allows the BenchMike Pro to operate with
both rotary and linear fixtures, in both motorized and non-
motorized configurations. Rotary fixtures include the ID/OD/Wall
and Belt Drive fixtures.
Most NDC Technologies fixtures contain an ID chip. The Intelli-
gent Fixture option allows the BenchMike Pro to read this ID chip
to identify the name and physical characteristics of the fixture including motor, encoder, gear ratio, end of travel
sensor, etc. If a fixture without an ID chip is being used, the BenchMike Pro must be set up manually to recognize
the fixture. See the
Setup
section.
The Rotary Position or Linear Position data item can be defined mathematically when an Intelligent Fixture is in
use. From Expression Editor, use the appropriate variable name in your expression: linpos1 or rotpos1.

Description of Fixtures
The following additional fixtures can be used with the BenchMike Pro.
NOTE: If you have a manual fixture, the BenchMike Pro will ask you when to start and stop measurements at
each position. Motorized fixtures communicate this information directly to the BenchMike Pro.
