Model 657 29

– If a load greater than 200 kg or 300 kg

is placed on the scale,

St0P appears in

the display.

– To switch off the scale, press the Start

key again.

Switching the weighing range

The seca 665 has two weighing ranges which can be selected. Weighing range 1 has a

reduced maximum capacity but greater display resolution, whilst weighing range 2 allows

you to use the maximum load capacity of the scale. Depending on the application in ques-

tion, you decide whether you would prefer to use the fine display resolution or the high

load range.

– Switch on the scale at the green Start

key. The scale initially operates in the

weighing range last selected.

– To change the weighing range, press

the key .

– A triangle in the display indicates the

weighing range active in each case.

This remains active even when the scale

is turned off.

Note:

It is possible to switch from Range 1 with fine graduations to Range 2 with coarse grad-

uations with a load on the scale unless the scale is switched to a special function (like pre-

Tare, for example). For technical reasons, it is only possible to switch from coarse Range

2 to fine Range 1 with no load on the scale. In this case too, no special function may be

activated.

Switching off the scale

– To switch off the scale, press the Start

key again.
