Function
If this key is only set for HOLD (P2=0), press to enter or exit the HOLD mode.
If this key is only set for PRINT (P2=1), press to output the data according to P4 setting.
If this key is only set for HOLD and PRINT (P2=2), press to output data according to P4
setting and hold the current weight.
Choose weighing units; lb, kg, lb:oz
Note: The weighing units that can be used are restricted by display division, and
calibration weight unit (restricted by P8, P9, and P10)
For example, if the calibration unit is kg; calibration display resolution is 50kg (that
means: P8=5, P9=0, P10=0). If the UNIT key is pressed to choose weighing units, lb or
lb:oz are not allowed to choose since the display resolution of 100lb or 2000oz is not
available to this indicator.
Tare function
This function can be activated only when the scale is in stable mode and the gross
weight is not a negative value.
Power on
Zero function: When the weight is within zero range, it will activate as ZERO function
and clear the tare weight. When the weight is not within the zero setting range (P13),
the scale will show 0----- (zero point is over the setting range) or 0_____ (zero is below
the setting range).
Power off
ignore modification
Prepare to exit from current working mode
