Press ‘SQ’ (
<
) for 1 second to access the ‘ con -
figuration menu
’. For a description on how to op -
erate inside the menus see section
1.12.1
. For a
full vision of the ‘
configuration menu
’ structure
see section
1.13
.
At the initial set up of the instrument, first configure the
theoretical part of the load cell at the ‘ Load cell param-
eters’ (‘ cELL ’) menu and later configure the empirical part of
the load cell at the ‘ Field correction ’ (‘ F.cor ’) menu. See sec-
tion
1.12.2
for additional information.
• at the ‘ Decimal point ’ (‘ dP ’) parameter, select the deci-
mal point position. Move the decimal point with key ‘LE’
(
3
). The position defined will be used for all reading pa -
rameters.
Example : to read in ‘Kg’ with tenths of kilograms, place the
decimal point at ‘XXXXX.X’ and the reading will be always
be shown with 1 decimal.
Changing the position of the decimal point will only light a
different decimal point led, but will not modify or re-scale
the measure of the instrument.
• at the ‘ Sensitivity mV/V ’ (‘ MV.V ’) parameter, configure the
value for the load cell sensitivity. Accepts any value between
0.0001 and 99.9999 mV/V. Default value is 2.0000 mV/V.
• at the ‘ Nominal weight ’ (‘ LoAd ’) parameter, configure the
nominal weight of the load cell. accepts any value between
0 and 999999. The decimal point will be shown in the posi -
tion configured at the ‘ Decimal point ’ (‘ dP ’) parameter. De -
fault value is 1000.
Example : for a 5 Kg cell, configure a value of 5000 to read
in grams.
• at the ‘ Excitation voltage ’ (‘ V.Exc ’) parameter, configure
the voltage to power the load cell. Select ‘5 Vdc’ or ‘10 Vdc’.
Default value is 10 Vdc. Select ‘LAb’ for a millivolt meter
mode in laboratory
(see section 1.16.5) .
The ‘ Field correction ’ (‘ F.cor ’) menu includes the functions for
the empirical configuration of the load cell. See section
1.12.2
for additional information on each function.
• at the ‘ Low weight correction ’ (‘ F.Lo ’) parameter, intro -
duce the real value of the actual weight at the cell. Use the
lowest weight possible, close to 0. Press key SQ (‘
<
’) to
start the correction process.
• at the ‘ High weight correction ’ (‘ F.hI ’) introduce the real
value of the actual weight at the cell. Use the lowest weight
possible, close to nominal weight of the cell. Press key SQ
(‘
<
’) to start the correction process.
The ‘ System zero ’ (‘ S.ZEr ’) entry assigns the actual weight to
the ‘system zero’ of the instrument. See section
1.12.2
for ad-
ditional information.
