1.13.5 Display filters
The available functions are:
• the ‘
Steps
’ (‘
StEP
’) function defines the reading to be
done in steps of 1, 2, 5, 10, 20 or 50 counts.
Example - selecting a step of 20 configures the reading to
change in steps of 20 counts (‘1420’, ‘1440’, ‘1460’, ...).
• the ‘ Memory of maximum ’ (‘ MAX ’) function displays the
maximum reading value stored in memory and allows to
reset this value. This parameter is directly accessible using
key ‘UP’ (
5
)
(see section 1.13.6).
• the ‘ Memory of minimum ’ (‘ MIn ’) function displays the
minimum reading value stored in memory and allows to
reset this value. This parameter is directly accessible using
key ‘UP’ (
5
)
(see section 1.13.6).
1.13.6 Fast access
The ‘
fast access
’ is an operator configurable menu. The op -
erator can access this menu with a single press of the front
key ‘UP’ (
5
). The configured menu entries will be accessible.
Eligible parameters to be accessed by this menu are:
• access to the alarm setpoints through the ‘UP’ (
5
) key al -
lows to read and modify the values.
• access to the maximum and minimum alarms through the
‘UP’ (
5
) key allows to read and reset the values. To reset
the memory values: visualize the value on display, press the
‘UP’ (
5
) key, when the ‘ rSt ’ message appears, press ‘SQ’
(
<
) . The instrument will return to the memory visualiza -
tion. Press the ‘LE’ (
3
) key to exit his menu.
The ‘
fast access
’ menu is not affected by the password func -
tion. This means that the configuration menu can be password
blocked, while some configured functions or parameters can
still be accessible to the operator through the ‘
fast access
’
menu.
• Super fast access
If only a single function is selected for the ‘
fast access
’ menu,
pressing the the ‘UP’ (
5
) key will shortly display the function
name and then automatically jump to the function value.
1.13.7 ‘on power up’ function
The ‘ On Power Up ’ (‘ on.Pu ’) functions allows to define a se -
ries of actions to activate when the instrument restarts after
a power loss. Functions available are a delay so the instru -
ment waits a defined time before starting to measure and
control, and the state of the alarms at power up. The func -
tions will apply only after a restart due to power-loss, they
will not apply after a restart due to changes in configuration.
Delaying the measure and control functions gives additional
time to elements of the system who are slower, so they can
start completely before the instrument begins to acquire sig -
nal and control the outputs.
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.
1.13.8 ‘LE’ key
The ‘LE’ (
3
) key at the front of the instrument can be config -
ured to activate several functions. Only one function can be
assigned to the ‘LE’ (
3
) key. Eligible functions are the alarm
unlock function
(see section 1.13.3).
