5-3. Secondary Calibration Procedure (Equivalent Calibration)
Equivalent calibration by entering the Output (in mV/V) of the load cell to calibrate the instrument.
The equivalent calibration function is not available for NTEP. Due to the replacement of weighing
controller provides against an emergency or miss-operation Span calibration, and no chance to do
actual load calibration, but have to continually operate the weighing system. It is a convenient,
temporary measure.
Release calibration inhibition lock by switching OFF the Lock Switch on
the rear panel. (Hardware Lock)
Release Setting Value Lock which inhibits the calibration. (Software Lock)
Select Load cell Excitation between 10V and 5V.
Register the Unit of the scale.
Register the position of Decimal Point.
Register the maximum capacity of the scale.
If the registered value is exceeded by 9 scale divisions, display shows over
scale “OFL2”.
Register the minimum scale division of the scale.
Enter the Balance value equivalent to the mV/V for calibration.
Enter in the output of load cell in mV/V.
If it is necessary, re-enter initial zero point.
Disable changing setting value related to calibration.
Turn on Lock Switch, disable calibration.

Notice
The set Balance weight must be equal or less than the set Capacity.
When use the rated load cell mV/V for equivalent calibration, the Capacity must be
equal to load cell capacity.
When connecting several load cells in parallel, it is possible to occur some differences
between input and output value due to voltage drop caused by connection or material of
lines.
In this case, register actual mV/V value to perform accurate calibration.
