5.7) Temperature compensation (G)
If you’re working in room that has no air-conditioning or if temperature of the
workpiece is high, you may ask for a correction of the measured value while taking
the variation in temperature of the workpiece into account along with its coefficient
of linear expansion. To have this done, set Temperature Compensation to ON,
then enter the temperature value of the workpiece with its related coefficient. The
height gauge temperature will automatically be measured by the sensor at half
height of the column.
You may input the workpiece temperature in either of the following ways:
-
OFF: for use of the preset value from the configuration menu.
-
Keyboard: for changing the value through the keyboard in measurement
mode.
-
RS : for capturing the value via the RS port in measurement mode.
-
RS Auto : for automatic value capture via the RS port before each probe
contact.
Switching the height gauge off causes your selection to be lost.
All values captured in this way will be corrected based on
the following information:
T
R
: Reference temperature (default value : 20°C)
T
C
: Height gauge temperature
T
P
: Workpiece temperature
a

: Coefficient of linear expansion of the height gauge
