6.4.6.1 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 6.2.1).

6.4.6.2 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 6.2.3) 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
In the "Simulation" menue, you can simulate the pressure as well as the current to test the
subsequent measuring chain.

The current simulation influences only the current output. The pressure simulation takes all
settings into consideration, including the damping and an active table function.
