8.4.1 Automatic update of the unit weight

The scale automatically updates the unit weight if the number of units on the scale is less than
the reference number of units. An acoustic signal sounds when the value is updated. It is safer to
check that the number of units is correct when the unit weight has been updated automatically.

This feature is deactivated as soon as the number of added individual units exceeds the number
of the reference number of units.
8.4.2 Presetting the maximum and minimum values for audible alarm
The HWZ counting scale has a programming function that emits an acoustic signal if a count or weight
specified by the user is either reached (minimum values) or exceeded (maximum values).
More information about the audible signal setting can be found in chapter 9 “Parameters”.

To make these presets, press the key.

The “Weight” display shows HI CNT. Using the 10-key keypad, enter the maximum value for a
count (number of units) at which an acoustic signal should sound and confirm with the key.

The “Weight” display now shows LO CNT. Using the 10-key keypad, enter the minimum value for
a count (number of units) at which an acoustic signal should sound and confirm with the
key.

The “Weight” display now shows HI NET. Using the 10-key keypad, enter the maximum weight at
which an acoustic signal should sound and confirm with the key.

The “Weight” display now shows LO NET. Use the 10-key keypad to enter the minimum weight at
which an acoustic signal should sound and confirm with the key.

You will now return to weighing mode.

To delete the preset values from the memory and thus deactivate the checkweighing function,
save the value 0 in each case.
8.4.3 Setting the acoustic alarm function
The acoustic alarm function can be set for the weight mode or counting mode, or it can be turned off.
The function is disabled by default.

To make the setting, press and hold down the key for approx. 5 seconds.

The “Weight” display now shows CHECK, the “Unit weight” display shows NET for an acoustic
alarm. The preset weight values are taken into account.

After pressing the key again, the preset number of units are taken into account for the acous-
tic alarm for approx. 5 seconds. The “Weight” display continues to show CHECK, the “Unit weight”
display now shows PCS.

Pressing the key again deactivates the acoustic alarm for approx. 5 seconds. The “Weight”
display still shows CHECK, the “Unit weight” display shows OFF.
8.4.4 Manual totaliser

The values (weight and number of units) on the display can now be added to the values in memory
by pressing the key. The “Weight” window shows the total weight. The “Count” window
shows the total number of units. The “Unit weight” window indicates how often the units were
added to the memory for totalisation. The values are displayed for 2 seconds before the scale
returns to normal weighing mode. This is also printed out if the optional RS232 data interface is
used.

The scale must return to zero or a negative number before another sample can be added to
memory.
