The following Programming Parameters are available only on General Purpose
DROs with firmware ending in “C” (part # 700-1600-236).
Pr 39 – Non-Linear Compensation Enable. [0 or 1]
Enables or disables the Non-Linear Compensation feature of the DRO.
Default = 0 (off)
Pr 40 – Non-Linear Compensation Interval. [0.5 to 10.0, 5.0]
Sets the distance interval used while performing non-linear compensation
calibration.
Default = 5” (127mm)
Pr 41 – Temperature Compensation Enable. [0 or 1]
Enables or disables the temperature compensation feature of the DRO.
Default = 0 (off)
Pr 42 – Temp. Comp. Low Position. Range: Any displayable position
This parameter indicates to the DRO the lowest (smallest) position of the
encoder under normal operation based on the ABS position.
If a new datum is applied to the ABS position, this parameter must be updated
for proper operation.
Default = 0.00
Pr 43 – Temp. Comp. High Position. Range: Any displayable position
This parameter indicates to the DRO the highest (largest) position of the
encoder under normal operation based on the ABS position. If a new datum is
applied to the ABS position, this parameter must be updated for proper
operation.
Default = 0.00.
Pr 44 – Temperature Compensation Coefficient. [10 to 999, 222]
This parameter allows the user to modify the temperature expansion coefficient
value used when temperature compensation is enabled. The value displayed is
internally multiplied by 10
-7
to yield an expansion in meters/meter °K x 10
-6
. For
example, the thermal expansion coefficient for aluminum is 22.2 m/m °K x 10
-6
.
This would be entered into the display as 222.
Default = 222
Range: 10 to 999 will yield values from 1.0 m/m °K x 10
-6
to 99.9 m/m °K x 10
-6.
Note: Coefficients MUST be in m/m °K, NOT in/in °F.
