(handle)
Adjustment conditions
Adjustment in free jet Ø 350 mm, reference
pressure 1013 hPa, flow against testo logo,
based on testo reference Laser Doppler
Anemometer (LDA).
The digital probe allows measurement values to be
processed directly in the probe. This technology eliminates
instrument measurement uncertainty.
For calibration, the probe alone (without the hand
instrument) can be sent away.
Calculating the determined calibration data in the probe
generates a zero-error display.
Preparing for measurement
> Remove protection cap from the probe head.
> Pull out the telescope to the required length. The individual
joints of the telescope click into place.
After the measurement
> Pull the protection cap over the probe head.
> Slide the telescope back, starting with the joints closest to the
handle. Make sure that there are no kinks in the telescope
