3. Displaying measured variables
The measured variables supply you with information regarding
the degree of cleanliness, the water saturation and the temper-
ature of the hydraulic system under investigation. The mea-
surement variables ISO, SAE and NAS are calibrated. They in-
dicate a measured value with an accuracy of ± ½ ISO code in
the calibrated range.
3.1. Measured variable - ISO
The measured variable is updated depending on the set mea-
suring time. The presentation appears as a 3-digit ISO code.
Example: ISO code 20.18.15
3.2. Measured variable - SAE
The measured variable is updated depending on the set mea-
suring time. The presentation takes the form of a channel of
the SAE class. Example: SAE class A = 13.4
3.3. Measured variable - NAS
The measured variable is updated depending on the set mea-
suring time. The presentation takes the form of a channel of
the NAS class. Example: NAS class, channel 15-25 = 13.2
3.4. Measured variable – Water Saturation
The integrated AquaSensor continuously measures the satura-
tion. The measured value is shown on the display as the water
saturation of the fluid, expressed as percentage saturation. Ex-
ample: 19.3% water saturation
3.5. Measured variable – Temperature
The integrated AquaSensor continuously measures the fluid
temperature. The output as Celsius °C or Fahrenheit °F can be
set under . Example: Temperature = 37.8 °C
