interference (EMI) which may cause erratic
readings.
Please turn off the meter to avoid the sensor
burned when you have finished testing the high
wind speed (more than 20m/s) and remove the
probe.
To extend the probe, hold the handle in one
hand while pulling on the probe tip with the
other hand. Do not hold the cable while
extending the probe.
Remove the sensor protective cover, make
sure the sensor window is fully exposed and
the orientation is facing upstream.
To retract the probe, hold the handle in one
hand while pushing on the probe tip with the
other hand. If the probe antenna binding,
please gently straightened probe, and then the
rest of the extension of section pressure back
and don’t pull the cable.
