3.2 Danger due to UV radiation
UV RADIATION!
The OilGuard is equipped with a UV LED with an emission wavelength of 280 nm.
According to the standard IEC/EN 62471 (Photobiological safety of lamps and lamp
systems), this LED is classified in Risk Group 3 (High Risk).
Exposure of longer than 3 seconds can lead to permanent damage to the eyes and
skin.

The UV LED is only accessible when the housing is open. The OilGuard is equipped with
an automatic cut-off device that puts the LED out of operation when the housing is
open.

Switch off the OilGuard when carrying out servicing duties, or wear UV goggles and
gloves.
3.3 Storing the calibration aids
3.3.1 Checking unit
WARNING!
Incorrect measurement following the use of a defective checking unit for recalibra-
tion.
The supplied checking unit has been adapted to the instrument. If a defective checking unit
is used for recalibration, the measuring accuracy of the instrument may be affected. If recali-
bration cannot be made due to the loss of the checking unit, the measuring accuracy of the
instrument also cannot be guaranteed.

A subsequently purchased checking unit is always delivered without values and first has
to be calibrated to a serviced instrument.

Store the checking unit in a protected, defined location.
