Calibration Trim

Read

Response

Format:

Set

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

Measured

Actual

The command C10010 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.

Analog Full Scale Velocity

Read

Response

Format:

Set

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.
