5.4 Connection - Summation

To measure the level in very high vessels, multiple instruments can be

cascaded.

Cascading means that two or several instruments are connected

which can together cover a longer measuring range.

The instrument acts as Master and all other instruments operate as

Slaves.

The pulse rates of all instruments are summed in the Master instru-

ment and converted into a common signal.

The Master instrument must have the function "Level". For this

purpose, select under the menu item "Setup/Application" the function

"Level".

Set the address setting (MGC) on the Master instrument to "0 - 0".

The address setting (MGC) on the Slave instruments can be freely

selected. Only the address "0 - 0" is reserved for the Master instru-

ment.
