Carrying out the sensor check
The sensor check is an internal functional check of the photometer that is carried out auto-
matically once a week as standard. This period can be set freely or deactivated completely
(
Menu\Spec. function\Check interv.
).
Independently of this automatic process, a sensor check can be started at any time manually
or via an external control signal.
Reference Manual
During the functional check, a 100% value is determined first. An optical filter is then moved
into the light beam and the resulting attenuation defined.
