To activate the set user level, you must enter a 4-digit number under PN51 as
a “locking code” and confirm it by pressing the [P] key for approx. 1 second.
On changing to programming mode, the unit jumps to the first authorised
program number. If user level PN52 = 3, then, for example, the parameters of
the alarm outputs can be changed, but changing the parameter of the
measuring input (PN0) is not possible at this user level.
In order to obtain access to all program numbers later (equivalent to user
level 0), you have to enter under PN50 the same code you entered before
under PN51. You must then acknowledge this by pressing the [P] key for
approx. 1 s. After this you have access to all program numbers.
Information
If the locking code becomes lost, the unit can be set to the
default value 0000 at the manufacturer's without any data
loss.
PN54: Allocation of functions of the zero key
By pushing of the zero key [O] functions like e.g. TARA and HOLD can be
actuated or an offset shift can be preset. By allocation of TARA the key needs
to be pushed for at least 1 second. The device confirms the function by
showing „0000“ in the display. With activated offset shift, the value in PN5 will
be added to the initial value directly by pushing the key. A display hold can
only be actuated for approx. 20 seconds. By pushing the zero key again one
turns back into the current measurement directly.
During HOLD phase the display flashes.
PN59: Display flashing
By activating the display flashing, various alarm states can be optically
reinforced. The trigger for the display flashing can be freely assigned to the
setpoint outputs.
PN60 to PN75: Alarm outputs
The behaviour of the alarm outputs can be influenced via various program
numbers. The data refer to the scaled measurement and are updated with the
set measuring time. A description of the various parameters is given in
chapter “6.3.4 Description of alarm outputs”.
