* : Performance criteria
A : The product shall continue to operate as intended during and after testing.
If the product is used as intended, any reduction in performance or loss of
function cannot be less than the performance level specified in the operating
instructions. When immunity tests with continuous electromagnetic phenomena
are applied, the performance level may be replaced by an acceptable reduction
in performance which is recovered without user intervention. An acceptable
reduction in performance is only permitted within a performance level if this
information is clearly provided to the user via documentation such as the
product’s operating instructions. Changes to the operating state or loss of data
are not permitted.
B : The product shall continue to operate as intended after testing. If the product
is used as intended, any degradation in performance or loss of function cannot
be less than the performance level specified in the operating instructions.
During testing, the performance level of the equipment may be replaced by
an acceptable reduction in performance if such a reduction in performance is
detailed in the EMC test plan. An acceptable reduction in performance is only
permitted within the performance level if this information is clearly provided
to the user via the product’s instruction manual or other documentation.
Unintentional changes to the operating state are permitted if self-healing is
possible. The loss of stored data is not permitted.
C : Loss of function is permitted if the function is self-recoverable or can be
recovered by operation of the control. The recovery procedure is described in
the operating instructions.

4.3 Applicable Standards
■ Laser beam safety
The measurement laser beam emitted by this product is classified as class 1
according to IEC 60825-1 specification.
The guide laser beam is classified as class 3R according to IEC 60825-1
specification. The guide laser beam is dangerous to the eyes and should not be
observed directly or aimed at other persons. Energizing the guide laser beam
can also be seen on the display as “ ”.
The Class is indicated on the label on the back of the product (see “Specification
of the laser beam” on page 18).
Class 1 and 3R indicate the degree of danger with respect to the laser beam, as
defined in IEC 60825-1 as follows:
Class 1 : Laser products that are safe to use for long periods of direct
observation in the beam, even when using telescopic optics.
Observation in the beam can still cause visual effects such as
blindness, especially in dark surroundings.
Class 3R : Although the level of radiant power exceeds the MPE for direct in
beam observation conditions, the AEL is 5 times stronger than the
Class 2 AEL (for visible lasers) or 5 times more powerful than the
Class 1 AEL (for invisible lasers) and therefore the risk of failure is
relatively low for these laser products. Because of the relatively low
risk, the requirements for manufacturers and the control criteria in the
national regulations for users are less stringent than for Class 3B.
Laser products of class 3R are not regarded as intrinsically safe, but
the risk is reduced.

CAUTION
The use of controls or adjustments or the
performance of procedures other than those
specified here may result in dangerous exposure to laser radiation.
