• Zero point adjustment with a full or empt

• Span adjustment with a full or empt
container (with/without pressure)
• Inte
ration time
• Reset to manufacturer’s defaults
5.2 Key Functions (only available for transmitters without display)
An error signal is caused by a current surge (21 mA or 3.6 mA; 5 sec) when
the zero point or span setting fall outside of the sensor’s nominal pressure
range during adjustments with existing pressure. No values are stored.
The keypad becomes inactive after 10 min. of disuse. All settings will de-
fault to previously stored values. Only settings that have been confirmed
with the "OK" function are stored.
