1.12.13 Fast access
The ‘ fast access ’ is an operator configurable menu. When
configured, the operator can access the most usual functions
with a single press of the front key ‘UP’ (
5
). Functions avail -
able are listed below :
• access to alarm setpoints from the front key ‘UP’ (
5
) al -
lows to read and modify the actual setpoint values
• access to the ‘stock units’ parameter from the front key
‘UP’ (
5
) allows to read and modify the actual ‘stock value’
parameter. See section
1.12.6
for additional information
about the ‘stock units’ function.
• values for ‘gross weight’ and ‘tare’ are accessible from the
front key ‘UP’ (
5
)
(see section 1.9.5).
To reset the tare value
visualize the value and press key ‘UP’ (
5
). When message
‘rSt’ appears, press key ‘SQ’ (
<
). The instrument returns
to visualize the ‘tare’ value. Press key ‘LE’ (
3
) to leave the
menu.
• functions ‘signal mV’, ‘exc. voltage’ and ‘exc. current’
five access to values for the input signal measured in mV,
the excitation voltage measured in Vdc between terminals
‘
sense+
’ and ‘
sense-
’, and the excitation current measured in
mA provided from the instrument to the load cell
These three functions act as an integrated voltmeter and
ammeter, to be used for troubleshooting purposes, as they
give information on the real signals received and provided
to the load cell.
1.12.14 ‘On power up’ function
The ‘
On power up
’ (‘
on.Pu
’) menu allows to define a series
of functions to activate when the instrument restarts after a
power loss.
Functions available are a delay on the activation of measure
and control functions, and a tare function.
These functions will activate only after a restart due to power-
loss, they will not apply after a restart due to changes in con -
figuration.
Delay the measure and control functions gives time to slow
system elements to start completely before the instrument
begins to acquire signal and control the outputs.
• access to maximum and minimum memories from the
front key ‘UP’ (
5
) allows to visualize the values. To reset the
maximum or minimum value, visualize the value, and press
key ‘UP’ (
5
). When message ‘rSt’ appears, press key ‘SQ’
(
<
). The instrument returns to visualize the actual memory
value. Press key ‘LE’ (
3
) to leave the menu
The ‘
fast access
’ menu is not affected by the password func -
tion, allowing to have a locked access to the general configu -
ration menu, while still some functions are accessible to the
operator through the ‘
fast access
’ menu.
• Super fast access
If only one function is configured at the ‘
fast access
’ menu,
pressing the front key ‘UP’ (
5
) will shortly read the name of
the function and then automatically show into the value.
While on delay mode, the instrument shows all decimal points
lightened and flashing, all alarms are deactivated, and there is
no signal acquisition or communications control. When the
delay time is over, the instrument starts its normal function -
ing.
