"Diagnosis" menue
In this menue you can view and configure various diagnostic information. The following
diagnostic functions are available:
Menue entry
Description
Counter
Display of operating hour counter and maintenance timer
Min/max values
Displaying and resetting the min/max values for the different
measured variables
Last error
Display and reset of the last critical error
Self test
Self test of the device like after applying the power supply
Maintenance timer
Management of maintenance intervals

6.5.7.1
Min/Max values
The min/max values save the maximum and minimum values of the different measurands
until they are reset by the user. The menue item that shows the min/max value, can also
be used to reset it. Some of the min/max values are also directly accessible from the
measured value display in the device data (see 6.3.1).

6.5.7.2
The maintenance timer
Using the maintenance timer, the device can signal the need for maintenance after a freely
selectable number of operating hours. The timer counts down from the start value. Mainte-
nance need is indicated by an icon in the display (see 6.3.3) and, if necessary, the HART
protocol.
When the maintenance timer has expired, the counter continues into the minus range thus
the degree to which the interval has been exceeded is also visible.

„Simulation“ menue
The different measurands and the current can be simulated in the "Simulation" menue to
check the subsequent processing of measured values.
The current simulation only affects the current output. The measurand simulations take all
settings into account, i.e. including the damping and active tank shape if necessary.
