Conditions on site

4.1 Ambient temperature

To obtain optimum measuring results, the nominal temperature range of
o
-10...+70 C (+14...+158 °F) has to be observed. Constant or, at the most,
slowly changing temperatures are most suitable. The specified temperature
coefficients apply to an ambient temperature changing no faster than 5 K/h.

4.2 Protection against humidity

Ambient humidity and tropical climates do not impair the function of the KMR.
The KMR complies with IP67 degree of protection according to EN60529.
IP67 means: Protection against the penetration of dust, and protection against
water, if the KMR is dived into water (test condition: 0.5 h in 1 m water depth).
To prevent penetration of condensation water, bend the cable to form a drip
loop.

4.3 External pressure

The permissible external pressure is 0...3 bar.
