• Outputting the Measurement Data

The results of offset measurement can be output to external device.
In offset measurement mode, the [F4] soft key which assigned (REC) will appear in measured r
esult display.

• Distance measurement mode of the offset measurement

Offset measurement will be done by N-time fine measurement mode.
