1. GENERAL INFORMATION
WTC precision balance enables fast and accurate mass measurements under
laboratory conditions.
The weighing pan, made of stainless steel and equipped with anti-draft shield,
is an integral part of WTC balance. Backlit LCD display ensures clear
measurement result. WTC balance is equipped with an internal battery (comes
standard), so it does not have to be connected to the mains.
WTC balance is equipped with the following interfaces: RS 232, USB type A,
USB type B. The interfaces enable cooperation between the balance and
peripheral devices (e.g. printer, computer, flash drive).
2. PRECAUTIONS
2.1. Maintenance
A. Prior first use, carefully read this User Manual. Use the balance only as
intended.
B. Balance to be decommissioned, should be decommissioned in accordance
with valid legal regulations.
2.2. Battery
WTC balance is supplied by NiMH-type battery (nickel-metal-hydrogen) of
1800-2800mAh capacity.
In case of prolonged storage of the balance in low temperature,
the battery has to be charged.
A worn out battery can be replaced only by the manufacturer or
by the authorized service.
The equipment including accumulators does not belong to
regular household waste. The European legislation requires
electric and electronic equipment to be collected and disposed
separately from other communal waste with the aim of being
recycled.

Notice:
Symbols on accumulators identify harmful compounds: Pb = lead, Cd =
cadmium, Hg = mercury.
3. WARRANTY CONDITIONS
A. RADWAG feels obliged to repair or exchange all elements that appear to
be faulty by production or by construction,
B. Defining defects of unclear origin defects and means of their elimination
can only be realized with assistance of manufacturer and user
representatives,
C. RADWAG does not bear any responsibility for defects or losses resulting
from unauthorized or inadequate performing of production or service
processes,
D. Warranty does not cover:
•mechanical defects caused by product exploitation other than
intended, defects of thermal and chemical origin, defects caused by
lightning, overvoltage in the power network or other random event,
•Inappropriate cleaning.
E. Loss of warranty takes place if:
•a repair is carried out outside RADWAG authorized service point,
•service claims intrusion into mechanical or electronic construction by
unauthorized people,
•the balance does not bear company protective stickers.
F. Warranty conditions outline the warranty period for rechargeable
batteries attached to the balance for 12 months.
G. For detailed warranty conditions go to the warranty certificate.
H. Contact with the central authorized service: (0-48) 384 88 00 ext. 106
and 107.

5. UNPACKING AND INSTALLATION
A. Take the device out of the packaging.
B. Place the balance on a flat and even
surface. Keep it far away from any
sources of heat.
C. Install the weighing pan and anti-draft
shields in accordance with fig.4.

6. START-UP
6.1. Levelling
•Prior first use level the balance. To level a balance
turn its feet, keep turning the feet until the air
bubble takes central position.
6.2. Powering the Device
Caution:
Balance can be connected to the mains only with a power adapter that comes
standard with the particular model. Nominal power supply of the power adapter
(specified on the power adapter data plate) has to be compatible to the power
from the mains.
Plug the balance to the mains – connect the power adapter to the socket, next
connect its connector to interface located at the back of the balance housing.
Turn the balance on or off using key.
Test of the display unit takes place right after connecting the balance to the
power, all the elements and pictograms are backlit for a short time. Next, the
name and the program number appear, the indication gets to ZERO (displayed
reading unit depends on the balance).
If the indication is different than zero, press button.
6.3. Battery Status
An internal battery comes standard with the balance. pictogram, displayed
at the top of the display, signals battery status.
Pictogram operation Overview
No pictogram Battery full. Standard balance operation.
Pictogram displayed
continuously Battery status low. The balance will shut down. Immediately charge the battery.
Pictogram blinks every 1 s. Battery charging. Balance connected to power supplier, the
battery is being charged.
Pictogram blinks every 0.5
s.
Battery error. Battery damaged.

6.4. Battery Power
•Simultaneously press and keys.
•Battery power given in %is displayed for 2s.
•Wait for the home screen to be displayed.
7. MAINTENANCE ACTIVITIES
Disassembly a weighing pan and other detachable components (the
components differ depending on a balance type – see: UNPACKING AND
INSTALLATION section).
Caution:
Cleaning anti-draft chamber while still installed may cause damage of the
measuring system.
7.1. Cleaning ABS Components
To clean dry surfaces and avoid smutching use clean non-colouring cloths
made of cellulose or cotton. You can use a solution of water and detergent
(soap, dishwashing detergent, glass cleaner). Gently rub the cleaned surface
and let it dry. Repeat cleaning process if needed.
In the case when contamination is hard to remove, e.g. adhesive, rubber, resin,
polyurethane foam residues etc., you can use a special cleaning agents based
on a mixture of aliphatic hydrocarbons that do not dissolve plastics. Before
using the cleanser for all surfaces we recommend carrying out tests. Do not
use products containing abrasive substances.
7.2. Cleaning Stainless Steel Components
Avoid using cleansers containing any corrosive chemicals, e.g. bleach
(containing chlorine). Do not use products containing abrasive substances.
Always remove the dirt using microfiber cloth to avoid damage of protective
coating.
In case of a daily maintenance:
1. Remove the dirt using cloth dipped in warm water.
2. For best results, add a little dishwashing detergent.
