Hold Velocity If Above The gauge will hold the last valid velocity reading above the value set in Hold
Velocity If Above when the gauge stops making valid measurements. Set this
to a high value to disable this function. This is useful if the product can not be
guided well enough to keep the product in the measuring region of the gauge.
The range is 0 to 999,999.999.
Velocity Hold Timeout Configures how long the gauge will hold the last reading when measurements
are not being made. (See the Hold Velocity if Above Setting). This setting can
be set to any value from 0 to 65535 milliseconds. A setting of 1ms is the
minimum hold time. A setting of 0 disables the timeout and causes the gauge
to hold the last reading forever.
Calibration Trim When set to 100.00% the gauge will use the factory calibration. The Factory
calibration is multiplied by the Calibration Trim percentage to modify the
calibration of the gauge. This can be used to compensate for shrinkage,
stretch or misalignment of the gauge. The range is 50% to 200%.
DIP Average Time Normally set to Factory Default. When not set to Factory Default, the range is
1 to 2047. The DIP is a forward running average applied to the Velocity output.
Use this to smooth the Velocity output of the gauge. The bigger the number the
more smoothing will occur.
User Update Rate Sets the rate the RS232, RS422 and Ethernet will be automatically updated.
The range is 1ms to 2s in 1ms increments.
Length Reset Value Configures the starting length when the length reset occurs. This setting can
be used to introduce a constant offset (positive or negative) to the measured
length readings. For example, when using two optical detectors to trigger the
external Material Present input, this setting would be set to the distance
between the sensors. This setting affects only the internal length output over
the serial port or over Ethernet—it does not affect the pulse outputs. For most
applications, this value should be set to 0.
Minimum Velocity Limit Sets the minimum (most negative) measureable velocity. When a velocity is
measured below this value, it will be ignored. Can be any positive or negative
value. To disable, set to a large negative value.
Maximum Velocity Limit Sets the minimum (most positive) measureable velocity. When a velocity is
measured above this value, it will be ignored. Can be any positive or negative
value. To disable, set to a large positive value.
Length Reset Input
Action
This configures the Length Reset input function. The Graphic on the side of the
pop up menu shows the action required to reset the internal length counter of
the gauge. For example: Rising
Edge Triggered is selected and
the graphic shows an arrow on
the rising edge of the pulse to indicate that
the length counter will be reset on the rising
edge of the reset pulse.
QF Warning Threshold Sets the Quality Factor value below which the Quality Factor Warning is
asserted.
QF Warning Timeout Configures the amount of time that the indicated Quality Factor must be below
the QF Warning Threshold before the Quality Factor Warning output is
asserted.
