Pipeline measurement method
During the measurement, make the probe's crosstalk interlayer plate be
perpendicular or parallel to the axial line of the pipeline. For a pipeline
with larger diameter, the probe's crosstalk interlayer plate should be
perpendicular to the axial line of the pipeline, but for pipeline with small
diameter, users should perform measurements making the crosstalk being
both parallel and perpendicular to the axial line of the pipeline and take
the minimum readout as the thickness value.
8 Maintenance and precautions

Power check
When the power is low, the low battery indicator will appear, at this
moment users should replace the battery in time, or it will affect the
measuring accuracy. The backlight can not be switched on for a long time,
because it is a big consumer of electricity.
Note: if the instrument did not used for a long time, please take out of
the battery to avoid leakage to damage the instrument.
