2. Basic Information
2.1 Proper use
The balance you purchased is intended to determine the weighing value of material to be weighed.
It is intended to be used as a "non-automatic" balance, i.e. the material to be weighed is manually
and carefully placed in the centre of the weighing plate. As soon as a stable weighing value is
reached the weighing value can be read.
2.2 Improper Use
Do not use balance for dynamic weighing. In the event that small quantities are removed or added
to the material to be weighed, incorrect weighing results can be displayed due to the "stability
compensation" in the balance.
(Example: Slowly draining fluids from a container on the balance.)
Do not leave permanent load on the weighing plate. This may damage the measuring system.
Impacts and overloading exceeding the stated maximum load (max) of the balance, minus a
possibly existing tare load, must be strictly avoided. Balance may be damage by this.
Never operate balance in explosive environment. The serial version is not explosion protected.
The structure of the balance may not be modified. This may lead to incorrect weighing results,
safety-related faults and destruction of the balance.
The balance may only be used according to the described conditions. Other areas of use must be
released by ACZET in writing.

unit etc. against shifting and damage.
5. Unpacking, Setup and Commissioning
5.1 Installation Site, Location of Use
The balances are designed in a way that reliable weighing results are achieved in common
conditions of use.
You will work accurately and fast, if you select the right location for your balance.
Therefore, observe the following for the installation site:
• Place scales on a stable, even surface
• Avoid extreme heat as well as temperature fluctuation caused by installing next to a radiator or
in the direct sunlight;
• Protect the balance against direct draughts due to open windows and doors;
• Avoid jarring during weighing;
• Protect the balance against high humidity, vapors and dust;
• Do not expose the device to extreme dampness for longer periods of time. Non-permitted
condensation (condensation of air humidity on the appliance) may occur if a cold appliance is
taken to a considerably warmer environment. In this case, acclimatize the disconnected
appliance for ca. 2 hours at room temperature.
• Avoid static charge of goods to be weighed or weighing container.
Major display deviations (incorrect weighing results) may be experienced should electromagnetic
fields (e.g. due to mobile phones or radio equipment), static electricity accumulations or instable
power supply occur. Change location or remove source of interference.

6
5.2 Unpacking/installation
Carefully remove the balance from the packaging, remove plastic cover and setup balance at the
intended workstation.

5.4 Rechargeable battery operation (option)
The internal battery is charged with the supplied mains cable.
Before the first use, the rechargeable battery should be charged by connecting it to the mains power
cable for at least 15 hours. The operating time of the battery is about. 90h. Charging time until
complete recharging ca. 12h.
To save battery life, the background light can be switched off in the menu (See chap.. 11 menu).
An arrow [▲] appearing on the weight display below the battery icon indicates that the
capacity of the rechargeable battery is low. The balance will be ready to operate for about another
10 hrs., then it will switch off automatically. Connect the power cable as soon as possible to load
the rechargeable battery.
5.5 Connection of peripheral devices
Before connecting or disconnecting of additional devices (printer, PC) to the data interface, always
disconnect the balance from the power supply.
With your balance, only use accessories and peripheral devices by ACZET, as they are ideally
tuned to your balance.
5.6 Initial Commissioning
In order to obtain exact results with the electronic balances, your balance must have reached the
operating temperature (see warming up time chap. 1).
During this warming up time the balance must be connected to the power supply (mains,
accumulator or battery).
The accuracy of the balance depends on the local acceleration of gravity.
Strictly observe hints in chapter Calibration.

9. Calibration
As the acceleration value due to gravity is not the same at every location on earth, each balance
must be coordinated - in compliance with the underlying physical weighing principle - to the
existing acceleration due to gravity at its place of location (only if the balance has not already been
adjusted to the location in the factory). This adjustment process must be carried out for the first
commissioning, after each change of location as well as in case of fluctuating environment
temperature. To receive accurate measuring values it is also recommended to adjust the balance
periodically in weighing operation.
9.1 Calibration Procedure
• Switch on balance Whilst balance is carrying out self-test (counts
down from 99… to 00…) and press at the same time.
“UnLoad” will be displayed, followed by flashing numeric value.
• Change by pressing the navigation keys (See manual chap. 8); select
desired setting; currently enabled digit will be flashing.
• Confirm value by “Load“ will be displayed.
• Place adjustment weight, stability display appears
• Now press key to confirm the calibration.
• After the adjustment the balance will carry out a self-test. Remove
adjusting weight during self test, balance will return into weighing
mode automatically. In case of an adjustment error or incorrect
adjusting weight the display will show an error message, repeat
adjustment process.

9.2 Linearization
Linearity shows the greatest deviation of a weight display on the scale to the value of the respective
test weight according to plus and minus over the entire weighing range.
If linearity deviation is discovered during a testing instrument control, you can improve this by
means of linearization.
• Carrying out linearization is restricted to specialist staff possessing well acquainted with the
workings of weighing scales.
• The test weights to be used must be adapted to the weighing scale's specifications.
• Observe stable environmental conditions. Stabilisation requires a certain warm-up time.
• After successful linearization you will have to carry out calibration.

10.4 Parts counting
Before the balance can count parts, it must know the average part weight (i.e. reference). Proceed
by putting on a certain number of the parts to be counted. The balance determines the total weight
and divides it by the number of parts (the so-called reference quantity). Counting is then carried out
on the basis of the calculated average piece weight.
The higher the reference quantity the higher the counting exactness.
• Place the reference quantity
• Press , the scales will change to quantity counting mode
Reference quantity of 10, P 10 will appear.
• Reference quantities of 10, 20, 50, 100 and 200 can be set by
pressing .
• Confirm by pressing

10.4 Parts counting
Before the balance can count parts, it must know the average part weight (i.e. reference). Proceed
by putting on a certain number of the parts to be counted. The balance determines the total weight
and divides it by the number of parts (the so-called reference quantity). Counting is then carried out
on the basis of the calculated average piece weight.
The higher the reference quantity the higher the counting exactness.
• Place the reference quantity
• Press , the scales will change to quantity counting mode
Reference quantity of 10, P 10 will appear.
• Reference quantities of 10, 20, 50, 100 and 200 can be set by
pressing .
• Confirm by pressing
You will briefly see a line on the screen before the scales show the
respective quantity
• To change between reference weight, total weight and quantity, press
the key.
• To return to weighing mode, press the key.

9.2.1 Linearization Procedure
In case of an adjustment error or incorrect adjusting weight the display will show an error message;
repeat linearization process.
• Place the second adjustment weight.
• After the apparition of the stability display, „LoAd 2“ will
be displayed
• Put on the third adjustment weight
• After the apparition of the stability display, „LoAd 3“ will be
displayed
• Put on the forth adjustment weight (max load)
• After the apparition of the stability display, „LoAd 2“ will be
displayed
• Third adjustment weight
• After the apparition of the stability display, „LoAd 1“ will be
displayed
• Second adjustment weight
• After the apparition of the stability display, „LoAd 0“ will be
displayed
• First adjustment weight (weighing plate empty)
• After successful linearization the balance automatically
returns to weighing mode.
How to carry out linearization:
• Switch on the balance and during the selftest press the and
the button at the same time. “LoAd 0“ followed by LoAd
1” will be displayed.

9.2 Linearization
Linearity shows the greatest deviation of a weight display on the scale to the value of the respective
test weight according to plus and minus over the entire weighing range.
If linearity deviation is discovered during a testing instrument control, you can improve this by
means of linearization.
• Carrying out linearization is restricted to specialist staff possessing well acquainted with the
workings of weighing scales.
• The test weights to be used must be adapted to the weighing scale's specifications.
• Observe stable environmental conditions. Stabilisation requires a certain warm-up time.
• After successful linearization you will have to carry out calibration.

10.5 Weighing with tolerance range
You can set an upper or lower limit when weighing with tolerance range and thus ensure that the
weighed load remains exactly within the set limits.
Exceeding or dropping below the tolerance range is indicated by an audio sound or optical signal.
Audio signal:
The audio sound depends on the setting in menu block “BEEP“ (See chap. 11 menu).
Options :
• 0 No audio sound during tolerance weighing
• 1 An acoustic signal sounds when load is within tolerance limits
• 2 An acoustic signal sounds when load is beyond tolerance limits
Optical signal:
The arrow symbols indicate whether load is within the two set limits.
The icons provide the following information:
1. Goods to be weighed above tolerance limit
2. Goods to be weighed within tolerance range
3. Goods to be weighed below tolerance limit
