HOLD and PEAK HOLD
The <HOLD> key implements a manual Hold function. The <PEAK> key
implements a Peak Hold function where the largest absolute weight, either positive
or negative is stored in the peak value (eg. -30 is larger than 25). The Hold
annunciator is active when the display is showing the held weight. Refer to Status
Annunciators page 20.
To perform the Hold function, do the following:
Press the manual <HOLD> key once to hold the current displayed weight.
Press the manual <HOLD> key again to return the display to normal weighing.
To perform the Peak Hold function do the following:
Press the <PEAK> hold key once to show the absolute peak weight reading.
Press the <PEAK> hold key again to return the display to normal weighing.
A long press of the <PEAK> hold key clears the peak value back to 0 (zero).
All printouts that print the displayed weight will use the held weight reading if it is
currently being displayed. K303 will not print while a weight is held.
11.2.6.
LIVE.WT
The <LIVE.WT> key is used to enable live weight averaging. With this feature, it is
possible to determine the weight of a continually moving mass (eg. livestock).
Press and hold the <LIVE WT> key to switch between normal weighing and live
weight mode. The display will briefly show NORMAL or LIVE.WT.
During normal weighing, this key operates exactly like a manual <HOLD> key.
In Live-Weight mode the following sequence is followed:
While the net weight is within the zero 'dead' band, the instrument shows the
current weight.
Press the <TARE> or <ZERO> key to clear any residual weight and return the
scale to the zero state.
Place the mass to be weighed on the scale.
Once the weight moves outside the zero 'dead' band the instrument begins to
calculate a long term average that compensates for any movement in the mass.
The instrument flashes the Hold annunciator and shows the current average
value.
The Hold annunciator is steady when the final sample weight is shown on the
display.
Press the <LIVE WT> key to force the sample to be re-calculated.
Once the weight is returned to the zero 'dead' band, the cycle can be repeated.
