11.2.5 HOLD and PEAK HOLD

The key implements a manual Hold function. The key implements a Peak Hold function where
the largest absolute weight, either positive or negative is stored in the peak value (e.g. -30 is larger than 25). The
Hold annunciator is active when the display is showing the held weight. Refer to Status Annunciators section 5.1.1.

To perform the Hold function, do the following:
• Press the manual key once to hold the current displayed weight.
• Press the manual key again to return the display to normal weighing.

To perform the Peak Hold function, do the following:
• Press the hold key once to show the absolute peak weight reading.
• Press the hold key again to return the display to normal weighing.
• A long press of the 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.

11.2.6 LIVE.WT

The key is used to enable live weight averaging. With this feature, it is possible to determine the weight
of a continually moving mass (e.g. livestock).
• Press and hold the 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 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 or 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 key to force the sample to be re-calculated.
• Once the weight is returned to the zero 'dead' band, the cycle can be repeated.

11.2.7 SHOW.T

The SHOW.T item stands for Show Total. The function key will be labeled .
The PRINT key is used not only to print the current weight but also to add that weight to the current total.

• When the key is pressed the indicator displays count followed by the number of items in the total.
• After this, TOTAL is displayed followed by the current total weight.

If the total weight is too large to display in six digits, the weight is shown in two sections labeled with the upper six
digits displayed before the lower six digits.
A long press of the key causes the total accumulated weight to be printed and then cleared. The
SERIAL:TYPE option must be set to PRINT to activate this function.
