DP20 Economical Multisignal meter Instruction Manual
The instrument has two menus accessible to the user :
Conguraon menu’ (key SQ) (<)
Fast access’ menu (key UP) (5)
Conguraon menu
The conguraon menu modies the conguraon parameters
to adapt the instrument to the applicaon needs. To access the
conguraon menupress for 1 second the SQ (<) key. This access
can be blocked by acvang the Password (‘PASS’) funcon.
While operang the conguraon menu, the alarm status is ‘hold’
to the status they had before accessing the menu, and the output
and control modules remain in error state. When leaving the
conguraon menu, the instrument applies a system reset, followed
by a brief disconnecon of the alarms and the output and control
modules. Funconality is then recovered.
For a detailed explanaon on the conguraon menu see secon
1.29, and for a full view of the conguraon menu structure see
secon 1.29.
Fast access’ menu
The fast accessmenu is an operator congurable menu, providing
fast and direct access to the most usual funcons of the instrument
with a single key pad stroke. Press key UP (5) to access this menu.
See secon 1.19 for a list of funcons eligible for fast access in
this instrument. The Password (‘PASS’) funcon does not block
access to this menu. Accessing and modifying parameters in the
fast accessmenu does not interfere with the normal funconality
of the instrument, and it does not generate any system reset when
validang the changes.
Front key pad descripon
Key SQ (<) - press the SQ (<) key for 1 second to access the
conguraon menu. Inside the menu, the SQ (<) key funcons
as a ‘ENTER’ key. It selects and accesses the menu opon currently
displayed. At menus with numerical value entries, it validates the
number displayed.
Key UP (5) - the UP (5) key gives access to the ‘fast access’ menu.
Inside the menus, it moves vercally through the dierent menu
opons. At menus with numerical value entries, it modies the digit
selected by increasing its value to 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.
Key LE (3) - inside the menus, the LE (3) key funcons as the
ESCAPEkey. It leaves the selected menu, and eventually, will leave
the whole menu. When leaving the conguraon menu with the
LE (3) key, the changed parameters are acvated. At menus with
numerical value entries, the LE (3) key allows to select the acve
digit. To modify the value of the selected digit use the UP (5) key.
Menu ‘rollback’
Aer 30 seconds without interacon from the operator, the
instrument will rollback and leave the conguraon menu or the
fast access’ menu. All changes will be discarded.
