Installation of the measuring probe

  1. Drill a hole (Ø 22 mm) in the duct/channel.
  2. Fasten the holder of the measuring probe with the enclosed screws.
  3. Remove the protective cap from the measuring probe.
  4. Set the probe to the desired insertion depth, according to the scale, and secure it with the clamp [7].

The air passage on the sensor should be in the centre of the duct/channel. The printed scale serves as an adjustment aid. For larger ducts/channels, select the maximum installation depth. Make sure that the direction arrow on the end of the sensor corresponds to the direction of the air flow.
