Finally the balance stays in a standby state of showing 0g, 0.0g in the display
Notice: the lasting time of --------- will be decided by the stability of the loadcell, thus, the
balance must not be located in an unstable surface or in the wind blow. If O flashes in the
display, it means the balance is not in a stable condition, calibration and counting operations
is not allowed.
CALIBRATION
The purpose for this operation is to calibrate the balance so as to achieve the best
performance in case there is obvious tolerance error in weighing or the balance is
located in different gravity due to different latitude.
It is suggested to warm up the balance over half an hour before calibration.
Remove all loads from the platter, press function key TARE to clear the readings to
0g ,0.0g.
Press and hold function key CAL for 3 seconds, release function key CAL when
"---CAL---" is shown in the display, a figure of standard weight will flash in the display,
put a standard weight on the platter accordingly, standby state "------" will be shown in
the display for a few seconds before the standard weight figure is shown in the
display, remove the weight, "------" standby state will remain for a few seconds before
the balance enter stable weighing mode, showing 0g ,0.0g.
It is recommended to make the operations twice to achieve the best calibration
result.
WEIGHING
When the balance is warmed up and calibrated, 0g,0.0g is shown in the display
indicating weighing mode, put the object on the platter, when stable, the weight of the object
is shown in the display.
TARING
When a loader is put over the platter, its weight is shown in the display, press function key
TARE, 0g, 0.0g will be shown in the display, indicating the weight of the loader is deducted,
put the object into the loader, when stable, the figure shown in the display is the weight of
the object.
PIECE COUNTING
Remove all loads from the platter, press function key TARE to clear the readings in the
display, press function key COU to enter counting mode, figure
10(default
sampling quantity) will
be
shown
