Numeric Value Registering Calibration - KYOWA WGI-400A Instruction Manual

3-4-3 Numeric Value Registering Calibration

This is a function that calibrates data by setting the indicated value to a reference (Initial) value. Conduct this
function after the actual load and sensitivity registering calibrations.
This function is used for pressure transducers for absolute pressure measurement or when already load is
applied and unable to obtain the actual load state. By registering the initial value of the transducer written in the
inspection report or registering an already measured initial value, a reference point equivalent to unload state
can be registered.
1) Changing to Sensitivity Registering Calibration Mode
Press the FUNCTION key more than 2 seconds. Function 'F-01' is displayed to be in function selecting
mode.
Press the → key to have the indicator display 'F-04' and press the SET key.
Then, the numeric value registering calibration is set.
2) Setting Initial Value of the Transducer
The currently set reference value is displayed and the highest-order digit flickers.
Press the → or ↑ key to set the set the initial value of the transducer in mV/V unit.
After numeric value is determined, press the SET key.
At this time, the Status Indicator operates as the minimum digit indicator.
3) Calibration End
Function 'F-04' is displayed. Press the CANCEL key.
Then, the measurement starts with the registered calibration value.
Note: Numeric value registering calibration is erased when conducting the actual load calibration and
sensitivity registering calibration.
Reference: Although, the rated output of strain gage transducers is generally expressed in [mV/V], it may
be expressed in other units. At that time, the obtained data is converted into other units.
