6.FUNCTIONS
・Zero tracking is the function to reset gross weight to zero automatically when
the state remaining the zero point drift within the zero tracking range
continues more than set period.
・ Zero tracking period must be set between 0.1 ~ 9.9 second and its range must
be set between 0 ~ 99 using 1/4 resolution interval of weight display.
For instance, 02 corresponds to 0.5 and 12 corresponds to 3 of weight
display.
Zero tracking range is not proportional to the Minimum scale division
regardless of the setting state of Minimum scale division.
Zero tracking does not work if you set the period to 0.0 sec. and range to 00.
Period / setting range :
Range / setting range :
・ Since zero tracking should work from the point at which the gross weight is
zero, it does not work when the weight is already over the tracking range.
Adjust the zero point by digital zero or zero calibration.
・ If the amount of zero adjustment to be made by digital zero or zero tracking
(deviation from the calibrated zero point) exceeds Digital zero regulation
value, the zero alarm status turns ON without zero adjustment.
