Calibration

This weighing indicator, converts an input voltage from a load cell to the "mass"
value, and displays it. Calibration is the adjustment function so that the scale
(indicator) can weigh correctly.

5.1.1. Items of Calibration Mode

There are seven items in the calibration function.
Basic Items
The minimum division ............... Setting the weighing interval.
The maximum capacity ............. Setting the maximum display.
Zero calibration.......................... When unloading any weight on the weighing unit
Span calibration......................... The function to measure an input voltage variation by
Optional Items (Sub-functions)
Range function............................ The function for a multi-interval scale. Select "dual
Digital linearization function........ The function to revise a linearity deviation using
Gravity compensation function... The function to revise weighing error between the
Caution The maximum display is less than or equal to 10000 divisions. This number
is calculated from the maximum capacity divided by the minimum division.
Check the accuracy of weighing instrument periodically.
Recommended mass, use a mass heavier than 2/3 maximum capacity.
