Insolation
1. Switch the device ON and place it onto the surface of the photovol-
taic module.
2. The insolation is displayed in the unit W/m² or BTU/hr/ft².
Angle of inclination
1. Press the
4
key for angle of inclination / compass bearing.
2. The angle of inclination with respect to the horizontal is indicated
on the LC display.
Null balance of the angle of inclination
1. Place the device onto a plane surface.
2. Press the
4
key for > 5 seconds until the "Z" symbol starts
flashing on the LC display.
3. Press the
4
key again to store the "+SET" value.
4. Turn the device by 180° and press the
4
key again to store the
"-SET" value. The angle of inclination has been balanced to null.
The "Z" symbol is shown on the LC display.
5. Press the
4
key again for > 5 seconds to exit the setting. The
"Z" symbol disappears from the LC display.
Compass bearing
1. Press the
4
key for angle of inclination / compass bearing.
2. To determine the cardinal direction, hold the device horizontally. As
soon as the angle of inclination e/- 20°, "- - -" appears on
the LC display and it is not possible to take a bearing.
3. Hold the marking
9
on the top of the device in the direction which
you would like to determine. The direction is displayed in degrees:
0° = North, 90° = East, 180° = South, 270° = West
4. Please observe that metallic objects or live conductors might affect
the measuring accuracy of the device.
