Calibration Function; Actual Load Calibration - KYOWA WGI-400A Instruction Manual

3-4 CALIBRATION FUNCTION

There are 3 calibration functions appropriate for the required purpose, that is, 'Actual load calibration' that
calibrates data by applying already known load to transducers (sensors), 'Sensitivity registering calibration' that
conducts calibration by registering a sensitivity value written in the transducer inspection report, and 'Numeric
value registering calibration' that calibrates data by registering input value to display Zero.

3-4-1 Actual Load Calibration

Actual load calibration is conducted by applying the actual load (already known load such as weight) to a
transducer.
Use a load cell having 'rated capacity: 1 kHz' and 'rated output: 2.004 mV/V.' An example shall be explained to
have the indicator display '100.0' when 100-kg load is applied.
1) Conducting Digital Zero
Set the transducer to no load state. Press the ZERO key to activate the digital Zero function and to set the
indication to '0.' Do not forget to conduct this digital Zero function to register the reference point.
2) Applying Actual Load
Apply the actual load to the transducer.
<Example> Gently apply 100 kg load.
3) Changing to Sensitivity Registering Calibration Mode
Press the FUNCTION key for more than 2 seconds. Function 'F-01' is displayed to be in function selecting
mode.
Press the → key to have the indicator display 'F-02' and press the SET key.
Then, the actual load calibration is set.
4) Setting Indicated Value
The currently set indicated value (Rated capacity) is displayed and the highest-order digit flickers.
Press the → or ↑ key to set the set the desired value (Actual load value) by ignoring the decimal point.
<Example> Set the indicated value to '1000' and press the SET key.
5) Setting Decimal Point Position
The current decimal point position flickers.
Press the → key and move the decimal point position.
<Example> Set the indicated value to '100.0' and press the SET key.
6) Calibration End
Function 'F-02' is displayed. Press the CANCEL key.
Then, the measurement starts with the registered calibration value.
