CHG1 The battery is very discharged and is being slow charged.
When sufficient charge has been put into the battery it will
switch to fast charge.
CHG2 The battery is being fast charged. When the battery is fully
charged it will switch to trickle charge.
CHG3 The battery is fully charged and is now being trickle charged to
maintain its charge.
A fully discharged battery will take around 7 hours to recharge.
5. CALIBRATION / SETUP
All calibration and setup functions are reached from supervisor mode.
Pressing ‘8’ then ‘ENT’ enters the calibration mode. A series of commands
are then available that are related to calibration. All commands are
constructed from an 8 digit number to avoid misuse.
93010001 - select cell #1 and display as raw value.
93010002 - select cell #2 and display as raw value.
93010011 - select cell #3 and display as raw value.
93010012 - select cell #4 and display as raw value.
93010003 - display all cells as calibrated value.
93010004 - mark start of calibration for selected cell.
90010005 - mark end of calibration for selected cell.
93010006 - save calibration values for all cells
93010007 - set and save zero offset.
93010009 - reload calibration values for all cells.
93020246 - clear data memory (does not affect calibration).
93030xxx - set node number.
93050xxx - set stability threshold.
93060xxx - program tag number into transponder.
93070xxx - set stability timeout.
Each load cell connected to the controller requires calibrating for span
separately, this requires removal of any platform if using a scale with more
than one load cell. The zero point is calibrated collectively.
5.1 EXAMPLE: CALIBRATING CELL #1
1. Ensure the scales are in supervisor mode.
