Zero tracking ( trc )
This function tracks zero point drift caused by changes in the environment and stabilizes the
zero point. When the weighing data is only a few digits, turn the function off for accurate
weighing.
trc 0
The zero tracking function is not used for weighing a very light sample.
trc 1 The normal zero tracking function is used for stable zero display.
trc 2 The strong zero tracking function is used for stable zero display.
trc 3
The very strong zero tracking function is used for stable zero display.
Display refresh rate ( 5pd )
Period to refresh the display. This parameter influences "Baud rate", "Data output pause"
and "Stream mode".
Note This item is selected automatically in the weighing speed adjustment.
Decimal point ( pnt )
The decimal point format can be selected.
Auto display-ON ( p-on )
When the AC adapter is plugged in, the display is automatically turned on without the
key operation, to display the weighing mode. Used when the balance is built into
ON:OFF
an automated system. 30 minutes warm up is necessary for accurate weighing.
Auto display-OFF ( poff )
When the AC adapter is connected and no operation is performed (inactivity state) for 10
minutes, the display is automatically turned off and the standby indicator illuminates.
Capacity indicator ( g5i )
In the weighing mode, the indicator displays the weighing data relative to the weighing
capacity in percentage. (Zero = 0%, maximum capacity = 100%)
When the "Data memory (

value), the indicator displays the information stored in memory, such as the amount of
memory data or data number.
Accumulation function ( add )
The accumulation function adds the weighing data, displays and outputs the total value.
Refer to "6-5. Accumulation Function." for details.
Display at start ( rng )
When the weighing accuracy is not so strict, the smallest displayable weighing value can be
turned off without any key operation at weighing start. Useful when the balance is built into
an automated system.
