A): At an ambient temperature of 20 to 23 °C and an emissivity of > 0.999, measuring distance: 0.3 m, operating time: > 5 min, aperture of 60 mm

B): Plus use-dependent deviation (e.g. reflection, distance, ambient temperature)

C): Depends on battery in use

D): At an ambient temperature of 20–30 °C

E): Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected.

F): In accordance with standard VDI 5585
