C Calibration Trim
C<CR> Read
Response Format: <N>
C<N><CR> Set
<N> is a number between 5000 and 20000, corresponding to 50% to 200%. This allows the
calibration number to be adjusted by the values from 0.5000 to 1.9999. The factory
calibration will adjusted by (Calibration Trim/10000).
This value should normally be left at 10000 (100%). Do not change this setting unless you
know exactly how it will affect your process. LaserSpeed gauges are permanently factory
calibrated to a NIST standard, and should not require trimming.
Example: If a calibration product of length 1000m is run through the gauge and it measures
999m due to an alignment error, the trim adjustment should be set to:
10010
999
1000
10000
10000

The command C10010<CR> would set the value to the 100.10%.
Note: Changing this setting will cause a reset, will reset the indicated length, and will cause
the pulse outputs to be momentarily interrupted. Do not change this setting during normal
operation.
D Analog Full Scale Velocity
D<CR> Read
Response Format: <N>
D<N><CR> Set
<N> is the velocity value * 1000 corresponding to the full scale output of the 0-2V analog
output. The Analog Output is described in detail in the Analog Output Voltage
section.
When this setting is set to 0, the Analog Output represents the Quality Factor on a 0-1V
scale.
Note: Changing this setting will cause a reset, will reset the indicated length, and will cause
the pulse outputs to be momentarily interrupted. Do not change this setting during normal
operation.
