Orientation
Normally the MetPak is mounted on a vertical pole, ensuring a horizontal Measuring Plane.
See Figure 3 Alignment & Mounting details
For indoor use the unit may be mounted with the Measurement Plane set to any required orientation.
Alignment
The MetPak should be aligned to point to North, or any other reference direction –for example, the bow of a boat.
There are two arrows, a coloured rectangle, and an alignment notch to aid alignment.
See Figure 3 Alignment & Mounting Details
Note : It is usually simpler to work first with a compass at ground level and identify a suitable landmark and its bearing.
Mounting
Pass the cable through the pole.
Note: the customer must
fit appropriate strain relief to the cable.
It is the responsibility of the customer to ensure that the MetPak is mounted in a position clear of any structure which
may obstruct the airflow or induce turbulence.
Do NOT mount the MetPak in close proximity of high powered radar or radio transmitters. A site survey may be
required if there is any doubt about the strength of external electrical noise.
Temperature ans Humidity Probes should be mounted inside of the Radiation Shield as shown in Fig 3 section 3.3.
