Recalling the Last Datum Setting For
International Units
If you’re using 5µm MICRO-LINE scales, MICRO-LINE can retrieve
your last datum setting when you power up your system. This feature is
especially useful when you have to shut down the system in the middle
of a job, or if a power interruption occurs. When power is restored,
MICRO-LINE will use Position-Trac TM technology to read the scales’
reference marks and recall the datum within seconds.
The recall feature only works after you have completed the initial
system setup and established a datum, so it won’t be accessible the
very first time you turn on the readout. After you’ve completed those
operations, you can recall the datum for every power up thereafter.
To recall your last datum:
• Power up the system.
• Press the CLEAR key to clear the E1 message.
• Press the decimal point (.) on the readout’s keypad. Move the
tool in the positive count direction along the X-axis. Keep
moving it until the system recalls the datum and “found”
flashes on the screen. The system will automatically reset the
X-axis value to reflect the distance from the tool’s current
position to the datum.
Repeat this procedure for the Z-axis, always moving the
tool in the positive count direction.
After you’ve completed the recall procedure, you can move to the datum by
positioning the tool until the display reads “0” for each axis.
Note: If Input 3 is being used, the datum will not be correct until both the
Z-axisand Input 3 scales have been recalled.
