2. PRECAUTIONS

2.1. Maintenance

A. Before first use of the balance, it is highly recommended to carefully

read this User Manual, and operate the balance as intended.

B. Balances to be decommissioned, should be decommissioned

in accordance to valid legal regulations.

- 5 -

2.2. Accumulator / battery pack

Balances WTB are devices designed to be powered from NiMH batteries
(nickel-metal-hydrogen) with rated voltage of 1.2V, size R6 and capacities
from 1800 to 2800 mAh charged while plugged to mains without
stopping operation.

A balance plugged to mains continuously monitors the battery status and
charges it if necessary. After sudden power failure from the mains, the
balance automatically switches to accumulator without breaking operation.

In case of an elongated storage period in low
temperatures, it is not allowed to fully discharge
the batteries which are instrument’s standard equipment.

A worn out accumulator can be exchanged to a new
one by the authorized service of the manufacturer.

The equipment including accumulators does not belong
to your regular household waste. The European legislation
requires that electric and electronic equipment be collected
and disposed separately from other communal waste with
the aim of being recycled.

Notice:
Some symbols on accumulators identify harmful elements/compounds:
Pb = lead,
Cd = cadmium,
Hg = mercury.

20. COOPERATION WITH TEMPERATURE SENSOR

The standard design of the balances, includes temperature sensor TB-1,
which is used for temperature measurement of the liquid.

Connecting the temperature sensor to the balance is automatically
confirmed by a message <SnS on> visible on the display. Simultaneously,
the temperature value used during the process of sample weighing in
liquid is automatically acquired from the connected sensor.

Disconnecting the sensor is automatically signaled by a message
<SnS oF> visible on balance’s display. Simultaneously, the temperature
value used during the process of sample weighing in liquid is acquired
from parameter <P4.1. tcnP>.

21. COMMUNICATION PROTOCOL

21.1. General information

A. A character based communication protocol balance-terminal is

designed for establishing communication between a RADWAG
balance and a peripheral devices via RS 232 interface.

B. It consists of commands sent from a peripheral device to the

balance and responses from the balance.

C. Responses are sent from the balance on each receipt of a

command as a reaction for a specific command.

D. Commands forming the communication protocol enable obtaining

data on balance's status and influencing its operation, e.g.: request
measurement results from the balance, zero indication, etc.

21.5. Manual printouts / automatic printouts

Balance WTB/AU series enables generating manual or automatic printouts.

• Manual printouts: press key on stabilization of indication

(measurement result),.

• Automatic printouts is generated automatically, and enabled on
loading a weighed object on weighing pan and stabilization of
measurement result.

Caution:

If a balance is verified, printouts of immediate values (unstable indications)
are blocked.
