( * )

When using the closed cover cap, there is no pressure compensation of the measuring cell any more� This results in measurement deviations caused by:

• fluctuations of the atmospheric pressure

• pressure fluctuations inside the unit in case of temperature fluctuations

(Δ 10 K ≤ 30 mbar).

6 Electrical connection
