6.4.5 Gain Setting
Measuring accuracy and consistency of readings are influenced by the material to be measured and
its composition. In order to meet the requirements for accurate measurement, it is requested to set
the gauge according to the special characteristics of a sample and measuring conditions.
For the majority of materials and conditions the auto gain adjustment will be sufficient whereas some
specific measuring tasks might require specific gauge settings. For gain setting, the gauge offers
four different working modes: Auto, Low, Medium and High.
Auto:
This mode matches different transducers and is suitable for the majority of
measuring requirements.
Low:
Suitable for high scattering and materials exhibiting low attenuation properties.
Medium:
Suitable for a large field of applications.
High:
Suitable for high attenuation materials.
6.4.6 Switch Off Mode
Both models, MiniTest 430 and 440, offer three different service modes:
•
after 2 min: automatic switch off after two minutes of idle state
•
after 5 min: automatic switch off after five minutes of idle state
•
disable: automatic switch off is disabled, the gauge is in continuous operation
Note:
When the automatic switch off has been disabled, make sure to switch off the gauge
manually after use in order to save power.
