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.

12.2. Autozero function
The autozero function has been implemented in order to assure precise
indications of a balance. This function controls and corrects “0” indication.
If enabled, the function continuously compares the results with constant
frequency. If two sequential results differ less than the declared value
of autozero range, then the balance is automatically zeroed and the
pictograms
and appear on the displayed.
When AUTOZERO is disabled zero indication is not corrected
automatically. However, in particular cases, this function can disrupt
the measurement process e.g. slow pouring of liquid or powder on the
weighing pan. In this case, it is advisable to disable the autozero function.
