The further you are from the wall, the wider is the area (a) that the Multi-Purpose

measurement area.
False!

The display illumination glows during the measurement. If a button is not pressed
within ca. 15 seconds, the illumination extinguishes. After a further ca. 15 se-
conds the diplay itself switches off. Press the button READ
display and the illumination.

Inaccurate measurements can also occur through a weak battery.
If the battery is too weak, the battery symbol appears in the display.
