2.14. Peak Weight

The Peak Weight feature records the heaviest stable or unstable load t placed on the scale, and its time and date.

1.Press and hold ZERO for three (3) seconds.

–The display will alternate between the Peak Weight Value, the time and date for thirty (30) seconds, then return to the Weigh Mode.

2.Press UNITS to end the process. and exit to the Weigh Mode.

–Pressing the UNITS key will not clear the accumulator.

∙Conditional upon programming the Operating Mode to ACCUMULATION,
