should be returned for repair (see Warranty section).

PEr3  = Printer mechanism fault - repair needed (see Warranty

section).

PEr4  = Printer clutch jammed - reset the printer (see page 28).

MEMORY ORGANIZATION

Capacity: 8,000 data samples which are divided into 16 pages.

Each time a new logging period starts, it automatically starts from a
new page.

If “LOGGING” is still on, and the available page is “0” the meter will
overwrite the first LOT DATA in the existing meter memory. During
logging the meter automatically returns to the oldest page in the
memory and if it contains data, it will overwrite. In this case the first
log will not correspond to the oldest set of data

It is recommended to periodically “clean” the memory. Save data
with PC if you need to keep a record and then disconnect the
batteries for about 1 minute. If you do this, remember to set the date
and time, once the batteries have been connected again.

ATTENTION:

Data are stored into memory until batteries are removed.

If replacement of the batteries is needed and data are not to be lost,
plug the adapter in and proceed with batteries replacement as
described below. Only once batteries have been replaced it is possible
to unplug the adapter without loosing the stored data.
