Using the scales
2
If you use the display consistently and logically, you will soon discover the universally powerful capacity of the scales. Many functions only require one push
of a button - memory functions are available with just a few frequently used
key sequences.
The clearly laid out keyboard is divided into blocks of keys:
Control keysFunction keys
Numerial keysCommand keys
Numerical keys
Function keys
Command keys
Control keys
An acoustic signal confirms that the
entry is correct
Incorrect entries are indicated by means
of five acoustic signals in swift sucession.
Please check that your entry is correct. If
necessary, cancel the command sequence
by pressing the ”CI” key.
Loading values
Loading the value which is in the secondary display or which has been entered
manually using the numeric keyboard:
Press the ”Ld” command key.
Now enter the number of the memory in
which you wish to store the value.
Confirm your entry by pressing the
appropriate function key (in this case
”Tare”)
The procedure is the same for organisational data memory, limit value memory
and tare memory. The reference weight
memory is only available in counting
mode. Switch over if necessary.
Recall of stored value
Press the ”i” command key and the
number of the memory where the value
you want is stored. Please note that
reference weights can only be called in
counting mode.
Confirm your entry by pressing the
appropriate function key (in this case the
limit memory)
Tare memory values and (in counting
mode) reference weight memory values
are activated by pressing the function key
again (in this case the limit value memory).
Clear memory
Press the ”CI” command key. Then enter
the number of the memory you want to
clear.
Confirm your entry by pressing the
appropriate function key (in this case
Count). Simply overwriting the memory as
described under ”Loading values” also
deletes the current value.
3
The indicator 2761 has a wide range of memory options:
10 tare memories
3 memories for organisational data
3 memories for set points or limit values
in the weighing and counting mode
and in counting mode
40 reference weight memories
These memory options are operated by means of the
numeric keyboard manual entry
and for calling the relevant memory number

The first programmed data block is displayed (4-digit code number) after the key has
been pressed to activate printing (CAL step 19...24). The incrementing of the tens
column from left to right is achieved using the ”0” key as with user modifications.
Modifications with the numeric keyboard. The displayed value is transferred by pressing
the ”K” key. The next data block is then displayed.
Every print code requires a positioning/beginning of printing. The positioning has to be
additive, that is to say that in case of several data blocks in one line, you should subtract
the positioning of the blocks before. Each line closes with the code ”3.300”. An i.e. line
is programmed with ”3.300”, too. This means, that ”3.300” always creates a new line.
The print image presentation is terminated by ”3.400”. When the values are transferred
using the ”K”-key the display moves forward to the next CAL-step. You return to the
weighing mode by pressing the ”x10”-key.

Remedy
Check that your entry is
correct - if necessary interrupt

pressing ”C” or ”CI”.
Remove the items from the
weighing platform. Remove
any dirt. If the scales do not
