4.6.2 Diagnostic parameter menu
The diagnostic parameters show the current
temperature offset (from temperature calibra-
tion) and the diagnostic codes (error mes-
sages) that are active, beginning with the highest priority (Prio_1). If no other key is
pressed for 30 s, the instrument automatically
switches back to the measured value display.
4.6.3 Parameter settings
This function can be used to display and set
the values that are essential for start-up.
These are:
• Temperature coefficient (
α
value)
• Cell constant
• Meas. value for 4 mA current output
• Meas. value for 20 mA current output
The value being edited flashes. When the
desired value has been entered, it is
accepted with „
F ”, and the system advances
to the next parameter.
Adjustment ranges

Note:
A minimum distance between the 4
and 20 mA values is required (see
chapter 10)

an error is signalled if
this condition is not fulfilled.
