12. How to operate the instrument
The instrument is fully configurable from the 3 push button keypad and
the 4 red digit led display at the front of the instrument (see Table 16).
AT POWER-UP
When the power supply is connected, the instrument applies the
following sequence :
• the ‘ display ’ shows the firmware code ‘ b3.xx ’.
• the ‘ display ’ shows the configured ‘ units ’ and ‘ input range ’ (for
example: ‘ Lc’ and ‘15 ’ for 0/15 mV in load cell mode, or ‘ MV ’ and ‘ b15 ’
for ±15 mV in millivolt mode).
• the instrument is now in ‘ normal mode ’ of operation and the ‘ display ’
shows the ‘ information ’ configured at section 13.5.
FROM ‘NORMAL MODE’ OF OPERATION
From ‘ normal mode ’ of operation, the operator can access the following
functions:
• key ‘ SQ ’ (
<
) gives access to the ‘ configuration menu ’ (see section 12.3).
• key ‘ UP ’ (
5
) gives access to the ‘ force ’ menu (see section 12.4).
• key ‘ LE ’ (
5
) activates the ‘ messages ’ function (see section 12.5).
‘ECO’ FUNCTION (‘DISPLAY’ POWERED OFF)
The ‘Eco’ function powers off the display under the following conditions:
• the instrument is in ‘ normal mode ’ of operation.
• and there is no interaction from the operator for 60 seconds.
The decimal point remains active (flashing), indicating that the
instrument is working correctly. This is a configurable function, enabled
by default. To configure the ‘ Eco ’ function, see section 13.9.
12.1 Configuration system
12.2 ‘Normal mode’ of operation
HOW TO ENTER THE ‘CONFIGURATION MENU’
With the instrument in ‘ normal mode ’ of operation (see section 12.2),
press the ‘ SQ ’ (
<
) key and maintain for 1 second. The horizontal leds
light from bottom to top. When the upper led lights, the instrument
enters into the ‘ configuration menu ’.
When entering the ‘ configuration menu ’, the first menu entry ‘ Function
code ’ ( codE ) is displayed. See section 14 for a full view of the
‘ configuration menu ’.
If the ‘ SQ ’ (
<
) key is released before entering into the
‘ configuration menu ’, the horizontal leds light downwards from
top to bottom, and the instrument returns to ‘ normal mode ’ of
operation.
HOW TO OPERATE INSIDE THE ‘CONFIGURATION MENU’
Inside the ‘ configuration menu ’, use the front keypad to move through
menu entries, parameters, and select configuration values:
• Key ‘SQ’ (
<
) functions as the ‘ ENTER ’ key. It selects the menu entry
currently displayed. At numerical value entries, it validates the number
displayed.
• Key ‘UP’ (
5
) moves vertically through the different menu entries. At
numerical value entries, it modifies the selected digit by increasing its
value to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
• Key ‘LE’ (
3
) functions as the ‘ ESCAPE ’ key. It leaves the selected
menu entry, and eventually, will leave the ‘ configuration menu’ .
When leaving the ‘ configuration menu ’, the changed parameters are
activated. At numerical value entries, the ‘LE’ (
3
) key allows to select
the active digit. To modify a numeric value press the ‘ UP ’ (
5
) key to
increase the value ‘+1’. Press the ‘SQ’ (
<
) key to validate the value.
WHEN EXITING THE ‘CONFIGURATION MENU’
When exiting the ‘ configuration menu ’ without changes (either by
‘ rollback ’ activation or because there are no changes in the configuration),
the horizontal leds light down from top to bottom, and the instrument
returns to ‘ normal mode ’ of operation.
When exiting the ‘ configuration menu ’ with changes, the display leds light
a round shape while the new configuration is stored. When the round
shape is finished, a start-up is applied (see section 12.2). After start-up,
the new configuration is active and the instrument is in ‘ normal mode ’ of
operation.
‘ROLLBACK’ FUNCTION
If there is no interaction from the operator for 60 seconds, the instrument
exits the ‘ configuration menu ’ discarding changes, and returns to ‘ normal
mode ’ of operation.

Flashing
When the operator is inside the ‘ configuration menu ’, the output
signal will remain overranged at maximum signal. Additional
configurations are available at the ‘ On SQ ’ parameter (see
section 13.9).
When the operator exits the ‘ configuration menu ’, the output
signal is temporarily set to minimum value for a time
<5 seconds, while the instrument restarts.
