Reading the analog output
The current (I) or voltage (U) can be calculated for a given NAS
contamination class as follows:
I = 4.8 mA + NAS class x (19.2 mA - 4.8 mA) / 14
U = 2.4 V + NAS class x (9.6 V - 2.4 V) / 14
The current (I) or voltage (U) can be calculated for a given NAS
contamination class as follows:
NAS class = (I - 4.8 mA) x (14/14.4 mA)
NAS class = (U - 2.4 V) x (14/7.2 V)
NAS Maximum
The NAS maximum value designates the largest of the 4 NAS classes.
NAS class
2 µm
5 µm
15 µm
25 µm
Particle size

> 25 µm
The signal is updated after the measuring period has elapsed (the measuring
period is set in the PowerUp menu, factory setting = 60 s).
The NAS maximum signal is output depending on the maximum NAS class.
Example:
NAS classes
NASMAX (NAS Maximum)
NAS 6.1 / 5.7 / 6.0 / 5.5
For basic information about cleanliness classes, see page 124 ff.
The NAS classification consists of whole numbers. Better trend recognition is
based on a resolution of 0.1 contamination classes as supplied by the CS
1000.
To convert a decimal value to an integer, the decimal value has to be
rounded up.
For example: a readout of NAS 10.7 is, according to NAS, a class NAS 11.
