Measuring Inclination and Cardinal Direction
Place the Meter directly onto the PV panel to get accurate tilt.
For surfaces of rooftops with inclinations dierent than 0°, push the
ZERO button
for 2 seconds to reset the angle and measure the true
inclination of a solar panel.
≤ 90°
N
The compass measurement will require a two-step process for accurate
cardinal direction.
Step 1: Perform irradiance, temperature and inclination measurements with
meter placed on and aligned with the PV panel. The compass function will
show “---” when the tilt angle is above 20 degrees. At a tilt angle of <20
degrees any compass reading shown will be inaccurate due to the inuence
by surrounding metal objects.
Step 2: Perform the compass measurement away from the PV panel by
holding the meter or placing meter on a horizontal surface (0 to 20 degrees
tilt) pointing the tip of the meter in the direction that the PV panel faces. Keep
away from any metal objects.
Note
The compass will reference magnetic north. The compass reading will
be unreliable if the meter is placed on or near objects containing metal
(including solar panels, metal roofs, concrete surfaces with rebar, etc).
