1. Applications
The digital HWZ series offers precise, fast and diverse counting and checkweighing and is intended for
use in areas that are not regulated by law.
 Scales of HWZ series are represented by 3 odels with capacities up to 30 kg.
 All odels are equipped with weighing platfor s ade of stainless steel and with housings ade
of ABS plastic.
 All scales have sealed keypads with colour-coded e brane switches and three large, very easy-
to-read liquid crystal displays (LCD). The LCD display is equipped with a backlight that can be acti-
vated or deactivated.
 All scales have an auto zero function, an audible alar for preset weights, an auto atic taring, a
preset taring and a totaliser that allows to save and recall the nu ber of pieces as a total su .
 Power is supplied via a 230 V ains connection and a 6 V 4 Ah rechargeable battery.
2. Delivery contents
 Scale
 Rechargeable battery (integrated into the scale)
 Weighing platfor
 Cold device power cord
 Protective hood
3. Warnings
The scale co plies with the directives and standards for electrical equip ent, electro agnetic co pat-
ibility and the stipulated safety regulations. However, i proper use ay cause personal injury and da -
age to property.
Read the operating anual carefully before putting the device into operation. This will prevent da age
to the device. Keep the operating anual in a safe place.
The following instructions must be observed for safe and trouble-free operation of the scale:
Protect the weighing platfor fro i pacts and vibrations and do not overload the scale.
Handle the scale with care when it is carried around and always keep in ind that it is a
precision easuring instru ent.
Do not expose the scale to high te peratures, whether fro neighbouring devices or direct
sunlight. The liquid crystal display ay suffer da age.
Electronic scales ust be protected fro possible ingress of water. Use the scale in a dry
place. Clean the scale with a da p cloth. If water accidentally penetrates the device, switch
off the scale i ediately and allow it to dry well.
Never clean the scale with abrasive or aggressive cleaning agents. The housing thereby
loses its shiny surface and is ore susceptible to dirt.
In this case, before connecting the supplied power cord to the scale, ake sure that the
voltage on the na eplate atches the local power supply. Connect the power cord to the
local power supply.
Do not ta per with the scale! In case of proble s, consult your co petent custo er ser-
vice representative.

4. Set up of the scales
1. Carefully re ove the delivery contents fro the packaging.
2. Place the scale on a stable, horizontal surface. Do not place the scale on a shaky or vibrating
table as this will cause distortion of easure ent results.
3. To align the scale, adjust the four feet of the scale so that the air bubble is exactly in the centre
of the spirit level.
4. Re ove the weighing platfor fro the separate packaging and insert it carefully into the holes
on the top of the scale.
5. Connect the power cord to the connector on the botto of the scale. Switch on the scale. The
on/off switch is located on the right-hand side under the housing. When switching on the scale,
the weighing platfor ust be unloaded. The scale runs through a test progra e and
acknowledges the end of the routine with an acoustic signal.
If the weighing platfor is loaded when switching on the scale, the scale will not be properly
calibrated and ready for use.
Switch off the scale and repeat the switch-on process.
6. The scale is now ready for use.
7. For accurate easure ent results, the ite to be weighed ust be placed in the iddle of the
weighing platfor . The ite to be weighed should not protrude beyond the weighing platfor .

weight. Entering a value via the keypad saves
this value as a tare value.
Zero key Sets the zero point for all next weighing opera-
tions. Zero is displayed.
7. Display description
The scales have three digital display windows. These are “Weight”, “Unit weight”, and “Count”.

6 HWZ-190214-Rev006-UM-en
7.1 Weight window (WEIGHT)
This window has a 5-digit display to show the weight on the scale.
The arrows above the sy bols indicate:
Zero position
Low battery voltage,
Net Net weight
Stability
7.2 Unit weight window (UNIT WEIGHT)
This window shows the unit weight of a sa ple. This value is either entered by the user or calculated
by the scale. The weighing unit gra e is set for all scales.
An arrow indicator appears above the sy bol when the nu ber of units is insufficient to accurately
deter ine the nu ber of units. If the unit weight is not sufficient to deter ine an exact nu ber of units,
an arrow indicator appears above the sy bol
In both cases, the scale continues the process. The arrows only appear to warn the user of a potential
proble .
If a preset nu ber of units has been saved, a s all arrow appears above the sy bol .
7.3 Count window (C UNT)
 This window shows the nu ber of units on the scale or the value of the total nu ber of units. See
Section 6 (Operation).
 An arrow indicator appears above “Memory” when a value has been entered into e ory.
8. peration
8.1 Setting display to zero
 You can press the key at any ti e to set the zero point. All weighing and counting operations
are perfor ed fro this point. Nor ally, it is only necessary if the weighing platfor is unloaded.
When the zero point is reached, the “Weight” window shows an arrow indicator above “Zero”.
 The scale has an auto zero function to account for s all deviations or accu ulation of ite s on the
weighing platfor . It is still possible that you ust press to reset the scale to zero if s all
a ounts of weight are displayed while the weighing platfor is e pty.

HWZ-190214-Rev006-UM-en 7
8.2 Taring
There are two ethods of entering a tare value. The first is based on the weight that is on the weighing
platfor and the second is based on a value entered by the user.
8.2.1 First method:
 Set the scale to zero by pressing the key. An arrow indicator appears above “Zero”. Place
a container on the weighing platfor . The display will show the value of its weight.
 Press the key to tare the scale. The weight that was displayed is stored as the tare value
and this value is subtracted fro the display. Zero re ains on the display. An arrow indicator
appears above “Net”.
 When a product is added, only its weight is shown on the display. The scale could be tared a
second ti e if another type of goods should be added to the first. Again, only the weight added
after taring is displayed.
 When the container is re oved, a negative value is shown on the display. If the scale was tared
shortly before re oving the container, this value is the gross weight of the container plus any
products that were re oved. The arrow indicator above “Zero” is also on because the weighing
platfor is under the sa e condition as the last ti e the key was pressed.
8.2.2 Second method:
 This ethod allows you to enter a value for the tare weight using the keypad. This is useful when
you are using the sa e containers, or when the container is already full while the net weight is
required and the weight of the container is known.
 Re ove all objects fro the weighing platfor and press the key to reset the display to
zero. Enter the tare weight value (including the deci al point) using the keypad and press
to save the tare value. The weight has a negative value, identical to the tare value.
 Place the container on the weighing platfor .
 The display shows the weight of the container inus the tare weight.
 When the full container is placed on the weighing platfor , the tare value is subtracted fro the
gross weight. Only the net weight of the content is displayed.
 If the input value does not atch the digit incre ent on the scale, the tare value of the scale is
rounded up to the next possible value. For exa ple, if a tare value of 10.35 g is entered for the 6
kg/0.2 g scale, the scale will show -10.4 g.
8.3 Unit counting
8.3.1 Setting the unit weight
In order to perfor unit counting, it is necessary to know the average weight of the individual units to be
counted. This can be done by weighing a known nu ber of individual units and deter ining the average
unit weight fro the scale, or by anually entering a known unit weight via the keypad.

8 HWZ-190214-Rev006-UM-en
8.3.2 Weighing a sample to determine the unit weight
 To deter ine the average weight of the individual units to be counted, it is necessary to place a
known nu ber of units on the scale and then enter the nu ber of units to be weighed.
 The scale then divides the total weight by the nu ber of units and the average unit weight is
displayed. Set the scale to zero by pressing the key, if necessary. If a container is to be
used, place the container on the scale and tare as previously described.
 Place a known nu ber of units on the scale. If the “Weight” display is stable, enter the nu ber of
individual units with the nu eric keys and press the key.
 The nu ber of units is shown in the “Count” window and the calculated average weight is shown
in the “Unit weight” window.
 If ore units are placed on the scale, the weight and the nu ber of units will increase.
 If a nu ber is placed on the scale that is lower than the reference unit weight, the scale recalcu-
lates the unit weight and increases it. To lock the unit weight and avoid auto atic recalculation,
press .
 If the scale is not stable, the calculation will not be perfor ed. If the weight is below zero, the
“Count” window shows a negative nu ber of units.
8.3.3 Entering a known unit weight
 If the unit weight is already known, this value can be entered using the keypad.
 Enter the value of the unit weight with the nu eric keys and press the key. The “Unit weight”
window shows the value as entered.
 Place the units to be counted on the scale. The weight and the nu ber based on the unit weight
are displayed. When weighing in kg, the unit weight is displayed in gra es. When weighing in
lb, the unit weight is displayed in pounds.
8.4 Counting more units
 After the unit weight has been deter ined or entered, it is possible to use the scale for unit count-
ing. The scale can be tared to clear the container weight as explained in the previous section.
 After taring the scale, place the units to be counted on the weighing platfor . The “Count” window
shows the nu ber of units that was calculated using the total weight and the unit weight.
 It is possible to increase the accuracy of the unit weight at any ti e during unit counting: Enter
the displayed nu ber of units and press the key. You ust be sure that the nu ber shown
equals the a ount on the scale before pressing the key. The unit weight can be adjusted if it is
based on a larger nu ber of sa ples. This will allow greater accuracy when a larger sa ple size
is to be counted.

HWZ-190214-Rev006-UM-en 9
8.4.1 Automatic update of the unit weight
 The scale auto atically updates the unit weight if the nu ber of units on the scale is less than
the reference nu ber of units. An acoustic signal sounds when the value is updated. It is safer to
check that the nu ber of units is correct when the unit weight has been updated auto atically.
 This feature is deactivated as soon as the nu ber of added individual units exceeds the nu ber
of the reference nu ber of units.
8.4.2 Presetting the maximum and minimum values for audible alarm
The HWZ counting scale has a progra ing function that e its an acoustic signal if a count or weight
specified by the user is either reached ( ini u values) or exceeded ( axi u values).
More infor ation about the audible signal setting can be found in chapter 9 “Para eters”.
 To ake these presets, press the key.
 The “Weight” display shows HI CNT. Using the 10-key keypad, enter the axi u value for a
count (nu ber of units) at which an acoustic signal should sound and confir with the key.
 The “Weight” display now shows LO CNT. Using the 10-key keypad, enter the ini u value for
a count (nu ber of units) at which an acoustic signal should sound and confir with the
key.
 The “Weight” display now shows HI NET. Using the 10-key keypad, enter the axi u weight at
which an acoustic signal should sound and confir with the key.
 The “Weight” display now shows LO NET. Use the 10-key keypad to enter the ini u weight at
which an acoustic signal should sound and confir with the key.
 You will now return to weighing ode.
 To delete the preset values fro the e ory and thus deactivate the checkweighing function,
save the value 0 in each case.
8.4.3 Setting the acoustic alarm function
The acoustic alar function can be set for the weight ode or counting ode, or it can be turned off.
The function is disabled by default.
 To ake 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
alar . The preset weight values are taken into account.
 After pressing the key again, the preset nu ber of units are taken into account for the acous-
tic alar 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 alar 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 nu ber of units) on the display can now be added to the values in e ory
by pressing the key. The “Weight” window shows the total weight. The “Count” window
shows the total nu ber of units. The “Unit weight” window indicates how often the units were
added to the e ory for totalisation. The values are displayed for 2 seconds before the scale
returns to nor al weighing ode. This is also printed out if the optional RS232 data interface is
used.
 The scale ust return to zero or a negative nu ber before another sa ple can be added to
e ory.
