1 Safety Information
1.3.3 Equipment
LED The instrument is equipped with a light emitting diode (LED) as the light
source, complies with risk category 1 and poses a low photochemical risk of
retinal damage in the event of direct exposure for > 100 s. Exposure hazard
value (EHV) with a duration of < 100 s: 0.24 at 50 mm distance to the beam
exit.

There is no risk to skin under any operating conditions.
Safety
equipment
The LED is switched on using the mains switch on the device.

EHV = the exposure hazard value (EHV) is the relation between exposure level (EL) and the exposure
limit value (ELV). EL = extent of exposure to a source at a specified location for a proven duration. ELV
= maximum exposure level for eye and skin exposure to optical radiation which is not expected to result
in negative biological effects. The EHV is greater than 1 when the exposure level exceeds the exposure
limit value.
