6. Security rules
To avoid electrical shock or damage of the balance or
connected peripheral devices, it is necessary to follow the
security rules below.
•For power supply use only a socket with a ground contact.
•All repairs and necessary regulations can be made by authorised
personnel only.
•To avoid fire risk use a feeder of an appropriate type (supplied with the
balance). Pay attention that supply voltage is compatible with specified
technical data.
•Do not use the balance when its cover is opened.
•Do not use the balance in explosive conditions.
•Do not use the balance in high humidity.
•If the balance seems not to operate properly, unplug it from the mains and
do not use until checked by authorised service.
7. Environment protection
According to legal regulations it if forbidden to dispose
electronic equipment in waste containers.
(WEEE-Reg.-Nr. DE64249495).
•Please return wasted balance to the point of purchase or other company
specialised in recycling of wasted electronic components.

8.Working environment
+18°C
+33°C
When choosing a location to set up the balance, remember the following rules to
ensure proper working conditions and user-friendly operating:
-setup the balance on an even, flat surface leaving necessary room for easy access,
-maintain proper working temperature,
-avoid strong air drafts, vibrations, dust, big temperature changes and humidity over
90%,
-avoid locations with extreme heat radiation and electromagnetic or magnetic fields.

10
9.Preparation – the balance
1. Take the balance and all supplied accessories (a feeder, pan elements) out of the
box.
2. Place the balance on a stable ground not affected by mechanical vibrations and
airflows.
3. Level the balance with rotating rear legs 6 so that the air bubble in water level 7 at
the back of the balance is in the middle.
4. ( PCE-LSZ 100C - PCE-LSZ 600C only) Gently place the pan support 2 into the
socket in the balance mechanism through the pan ring 3 and put the pan 1 on the
pan support (PCE-LSZ 600C balances are equipped with a pan integrated with the
pan support).
5. ( PCE-LSZ 1000C - PCE-LSZ 4000C only) Place the pan supports 2 on the
mandrels at the corners of the casing. Place the pan 1 on the pan supports.

6. Plug a feeder to the power socket at the back of the balance.
7. Leave the pan empty and plug the feeder to the mains (230V). At the end of self-
tests, the balance displays zero indication and is now ready to work.
10.General rules
1. Weighed sample should be placed in the centre of the pan.
2. In balances with active → 0 ← key and with d=e, before placing a load on the pan
make sure that zero indicator is displayed. If not, press → 0 ← key and wait until
zero indication and zero indicator appears. In other balances the key does not
operate.
3. The balance is equipped with tare equal to its range. To tare the balance press
→ T ← key (left or right). Storing tare value does not extend measuring range, but
only subtracts it from a load placed on the pan. To make weight control easier and
to avoid range overdrawing, the balance is equipped with the load indicator
(graduated in percentages).
4. Weighing result should be read when the indicator " " lights, which signalises
stabilisation of a result.
5. When the balance is not used but it is necessary to be ready to work immediately, it
can be switched off by pressing I/key. The balance reading system is then
switched off to "standby" mode (signalled by the indicator "OFF"). To switch the
balance on press I/key. The balance is immediately ready to operate maximum
accuracy (after self tests).
6. The mechanism of the balance is a precise device, sensitive to mechanical strokes
and shocks.
7. The balance should not be used to weigh ferromagnetic materials due to accuracy
decrease.
Moisture in the air may condense on the surface of the balance when
transferred to the warmer environment. In this case leave the balance for at
least 4 hours unplugged from the mains for conditioning to avoid wrong
operating or damage of the balance.
Do not overload the balance more then 20% of maximum load
(Max). Do not press the pan with a hand.
Before transportation take off the pan (move it slightly and lift it up)
and the pan base and preserve from any damages.

11.Testing and calibration
To ensure reliable results it is advised to check balance accuracy with an object of
precisely known weight before and after each measuring session.
In case permissible error is exceeded calibrate the balance with an external weight
standard or contact an authorised service.
12.External calibration
Calibration with external weight standard should be performed in case balance
indications exceed permissible error. To calibrate the balance a service centre should
use calibration weight as stated in Technical Data table (or of better accuracy) with
valid calibration certificate.
Operation sequence:
Press key.
Press key several times to choose
calibration weight value.
To accept press → T ← button.
Wait until calibration process is finished.
When LOAD communicate put a calibration
weight on the pan and press → T ← key.
Wait until internal calibration is finished.
The display should indicate the weight
standard value.

13.Connecting the balance to a computer or a printer
The balance may send data to a computer or a printer through RS232C port.
When cooperating with the balance, a
computer should be equipped with a
program, which enables processing data from
the balance.
PCE Group offers computer programs
cooperating with balances. Demo versions
and program descriptions are available on
the website: .
There is also a freeware program for testing a
serial port of the balance.
We also offer:
•Computer wires
•Thermal printers
•Label printers
The balance sends weighing result after initialising signal from a computer or after
pressing key.
Data transmission protocol description (Long protocol)
Computer →Balance: initialising signal S I CR LF (53h, 49h, 0Dh, 0Ah)
Balance →Computer: balance indication in the following format (16 Bytes)
Byte 1 - sign or space
Byte 2, 11 and 14 - space
Byte 3÷4 - digit or space
Byte 5÷9 - digit, decimal point or space
Byte 10 - digit
Byte 12 - k, l, c, p or space

18.Paperweight calculation (PAPEr)
The paper scale is a high precision / resolution device for the determination of the
basis weight (in relation to a square meter of materials). This is the most accurate way
to determine basis paper / tissue weight. The scale displays the basis weight of paper,
tissue, fabrics ... directly in g/m² with 0.1 g/m² (0.001 g) resolution. This function
enables to calculate paperweight of 1m2of paper basing on samples of known area.
Weighing in g/m ²
By the pressing of the key one changes for the conventionally weighing between
the paper balancing function in g/m ² and in [g]. The paper balancing mode [g/m ²] by
the indication ▲in the left display corner suggested without that the unit [g/m ²] at the
display is indicated.
Weighing in g
Switch with the help of the key from the paper balancing mode into the
conventional balancing mode in [g]. Present them the sample on the weighing platform
of the balance. The weight of the sample is indicated to the balance at the display.
19. Serial port transmission parameters (F..-rS)
The function enables to set the following
transmission parameters (standard
parameters underlined):
-transmission speed (bAud: 1200, 4800,
9600),
-the number of bits in a byte (bit: 7, 8),
-parity control (PArItY: 0, 1; Odd: 0, 1),
-Continuous transmission – without using
, key, approx. 10 results per second
(SEnd: 0, 1).
To set desired transmission parameters
activate “F.._rS” function, choose
appropriate parameter and press → T ← key
to accept needed parameter value. The
example at the left presents how to set
transmission speed value to 9600bps.
To leave the function, choose “out” option.
