External Material
P
Input+
The External Material Present input is used to control
when the gauge will measure. The gauge will measure
when External Material Present is active and will not
measure when External Material Present is not active.
External Material Present is enabled and disabled via
serial commands for the gauge. See Serial Commands
listing in the gauge manual.

Elongation Analog
Output
Elongation Ratio Analog Output. Minimum and
Maximum are configurable. An output of 0V
corresponds to the Minimum Elongation, and an output
of 2.048V corresponds to the Maximum Elongation.

Velocity Analog Output. Minimum and Maximum are
configurable. An output of 0V corresponds to the
Minimum Velocity, and an output of 2.048V corresponds
to the Maximum Velocity.

Note:
The Laser interlock (Pins 18, 19) on the Status Port is in series with the
front panel Key Switch. The Key Switch and Pins 18 and 19 must be activated to
turn on the Laser.
External Material Present (MP)
This is an input to the bi-directional System Status port. This input is functional
only when the gauge is configured for External Material Present. When this
mode is at a Logic Low (or No Input), measurements are enabled. When this
input is at a Logic High (5
–30 volts), measurements are disabled.
