SITRANS LG260 - Operating Instructions

44284-EN-171021

The following data or settings for adjustment of the display and ad-

justment module are saved:

• 

All data of the menu "Setup" and "Display"

• 

The items "Sensor-specific units, temperature unit and linearisa-

tion" in the menu "Additional settings".

• 

The values of the user-programmable linearisation curve

The function can also be used to transfer settings from one instru-

ment to another instrument of the same type. If it is necessary to 

exchange a sensor, the display and adjustment module is inserted 

into the replacement instrument and the data are likewise written into 

the sensor via the menu item "Copy device settings".
