11 Operation
Correct operation and compliance with the measurement accuracy can only be en-
sured if the environmental conditions specified in the "Technical data" are adhered
to� Ensure that the maximum pressure range, measuring range and permitted
operating temperature are not exceeded�
After power on and expiry of the power-on delay time (approx� 0�5 s) the unit is in
the Run mode (= normal operating mode)� It carries out its measurement and eval-
uation functions and generates output signals according to the set parameters�
→ 8 Operating and display elements
• During the power-on delay time the outputs are switched as programmed: ON
for NO function (Hno / Fno), OFF for NC function (Hnc / Fnc)�
• If output 2 is configured as analogue output, the output signal is at the final
value of the measuring range during the power-on delay time�
