Exposure reserve

The exposure reserve indicates the light quantity reflected by the measurement object (as a rel-

ative factor without unit). The exposure reserve helps you with the following problems, among

others:

Check whether a valid measurement result is present (signal quality). The signal quality is

weak

▪ when the sensor is not optimally aligned, and

▪ when the distance between the sensor and measurement object is too large.

During ongoing operation: Check the front panel of the sensor for soiling – if the exposure

reserve decreases over time, it may be an indication of increased soiling of the front panel.

Use the histogram function for this purpose

Description

Output of the exposure reserve.

Description

Output of the signal quality.

▪ 0 = Valid signal

▪ 1 = Weak signal

Low signal quality can result in greater measured value er-

rors. Decrease the distance to the measurement object or

optimize the alignment of the sensor.

▪ 2 = Critical signal

Valid measured value acquisition is no longer guaranteed.

Decrease the distance to the measurement object or opti-

mize the alignment of the sensor.

LEDs blink if a critical signal is reached.

The alarm output is activated when no measured value can

be recorded anymore.
