10 Technical data for testo 416
• Adjustment conditions for flow probes:
Adjustment in free jet Ø 350 mm, reference pressure 1013 hPa,
based on testo reference Laser Doppler Anemometer (LDA).
•
Low flow velocities may result in greater measurement uncertainties
during humidity and temperature measurement! The probe should
be switched on outside a duct under the following conditions:
Ambient temperature: 20°C
Flow: approx. 0 m/s.
Collapse the telescope after use and do not constrict with the cable.
Start with the telescopic links closest to the handle.
