Process Unit 73 LF
The Individual Menus
Here, you have the Calibration menu as an example
for operator prompting using information
texts. You can choose between four different calibration
sequences.
Access can be blocked by a passcode (can also
be disabled).
During the calibration sequence, you get instructions
for each step. At the end, the determined
sensor data are displayed and stored.
The Parameter Setting menu is divided into
Viewing, Operator and Administrator level according
to the operator’s specialization.
On the Viewing level, the parameters can only be
displayed but not edited.
On the Operator level, only marked menu items
are enabled for parameter setting.
On the Administrator level, all parameter setting
functions are accessible. In addition, each item
can be marked to configure an optimum menu for
the Operator level.
Operator and Administrator level are protected
against unauthorized access by passcodes. For
the Operator level, the passcodes can also be disabled,
if required.
The Maintenance menu contains functions for
measurement point maintenance (rinsing and
cleaning the probe) and for temperature probe adjustment.
It also provides a current source function
for manual adjustment of the output currents, for
example in order to set controller parameters or
test external devices (recorder, indicator).
Access can also be passcode protected if required.
The Diagnostics menu provides information on
sensor and Process Unit.
Activated warning and failure messages are listed
in plaintext in the message list.
Furthermore, you can retrieve the cell constant.
Messages and function activations are automatically
stored with date and time in a logbook with a
storage capacity of 200 entries. This allows tracing
back events and QM documentation according to
ISO 9000. Comprehensive instrument testing
(memory, display and keypad) can be performed
on site using the diagnostics function.
