Offset Adjustment; Average Mode - IMKO SONO-VIEW Operating Instructions Manual

2017-05-24

1.1.2 Offset Adjustment

For compensation of measurement deviations caused by e.g. density fluctuations in the
material or by installation conditions, it is possible to linearly shift the measured value. This
menu item is used for this purpose. You can move the measured value between -10 and +10
percentage points. The set displacement is stored in the probe and then also affects the
analog output. The setting remains comprehensible.

1.1.3 Average Mode

This menu item allows you to switch on or switch over a measurement averaging in the
moisture probe. The configuration of SONO- probe is preset in the factory before delivery.
SONO moisture probes offer the following options:
Mode CS: (Cyclic-Successive) For very short measuring processes (e.g. 2...10 seconds)
without floating average and without filter functions, with internal up to 100 measurements
per second and a cycle time of 250 milliseconds at the analogue output. Measurement mode
CS can also be used for getting raw data from the SONO-probe without averaging and
filtering.
Mode CA: (Cyclic-Average-Filter) For relative short measuring processes with continual
average value, filtering and an accuracy of up to 0.1%
Mode CF: (Cyclic-Float-Average) for continual average value with filtering and an accuracy
of up to 0.1% for very slowly measuring processes, e.g. in fluidized bed dryers, conveyor
belts, etc.
Mode CK: (Cyclic-Kalman-Filter with Boost) Standard setting for SONO-MIX for use in fresh
concrete mixer with continual average value with special dynamic Kalman filtering and an
accuracy of up to 0.1%.
Mode CC: (Cyclic Cumulated) with automatic summation of a moisture quantity during one
batch process.
Mode CH: (Cyclic Hold) similar to Mode CC but without summation.
Mode CH is recommended for applications in the construction industry. If the SONO-
probe is installed under a silo flap, Mode CH can measure moisture when batch cycles are
very short, down to 2 seconds. Mode CH executes an automatic filtering, e.g. if dripping
water occurs.
