1.7 Functions
This section provides the information about functions of the MINI CK100 .
1.7.1 Zero and Span Automatic Calibration
Electronic Calibration (R-Cal) – Allows the calibration without application test weights. The
electronic calibration controls the instrument with load cell, the program inserts a precision
resistance (in parallel to load cell strain gauge) that simulates a weight variation. The
calibration constant is obtained with reference of load cell and scale data.
Calibration with Test Weights – Is necessary the installation of test weights on the scale.
1.7.2 Zero Tracking (AZT)
This function is performed executing continuous periodical zeroing actions, in order to
compensate the zero variations due to deposit of material or similar causes.
If for a selected time the instrument has a weight value different to zero, included a activation
value (Activation Range) selected, the AZT function provides executing zeroing actions.
The max value for autozero tracking is selected with Activation Range.
1.7.3 Current Output Signal (Optional)
A current output is available (0-20/4-20 mA). The output range and the function are selected
by keyboard. The functions available are the following :
•
Gross Weight
•
Net Weight
•
Tare
•
Peak
The current output has a filter and camping that can be selected.
