of the scale is in the middle. Lock legs with a nut.
correct wrong
5. Put on a pan.
6. Remove everything from a pan and plug the scale to the mains with a ground
connector. After self-tests and result stabilisation, the scale displays zero indication.
8. General operating rules
1. Before each measurement make sure that zero indicator is displayed. If zero
indicator does not displayed or “----“ communicate appears, press → 0 ← key and
wait until zero indication and zero indicator appears.
2. The scale is equipped with a tare equal to its range. To tare the scale press → T ←
key (left or right). Storing a tare value does not extend measuring range, but only
subtracts it from a load placed on a pan. To make weight control easier and to avoid
range overdrawing, the scale is equipped with a load indicator (graduated in
percentages).
3. Weighing result should be read when the indicator " " lights, which signalises
stabilisation of a result.
4. When the scale is not used but it is necessary to be ready to work immediately, it
can be switched off by pressing I/ key. The scale reading system is then switched
off to "standby" mode (signalled by the indicator "OFF"). To switch the scale on press
I/ key. The scale is immediately ready to operate maximum accuracy (after self
tests).

6. Protect the scale against dust, aggressive dusts and liquids. To clean it is advised to
wash the scale with water and dry it afterwards.
9. Connection with external devices (option)
The scale may send data to external devices (a computer or a printer) through RS232C
or RS485 port.
When cooperating with a computer, the
scale sends weighing result after initialising
signal from a computer or after pressing
key.
When cooperating with a printer data is send
automatically after result stabilisation, but
next transmission is possible after removing
previously weighted sample.
The scale sends following information:
successive number of weighing and
weighing result (see: printer cooperation
mode setting).
The scale may be equipped with the second
interface (optional) used for example for
continuous weighing result transmission to
an additional, external display.
When cooperating with the scale, a computer should be equipped with a program
which enables processing data from the scale – available by PCE Group with extra
charge.
