6.7 Parameter adjustment - Real value correction
To correct a level measurement, a real value correction can be carried
out when a certain level is reached. This is for example necessary in
case of recurring buildup on the vessel wall.
The level measurement can thus be reset to the correct real value.
The level measuring instrument acts as Master and the MINITRAC 31
operates as Slave.
First of all, define the function of the Slave instrument before you
define the Master instrument. The Master instrument can thus imme-
diately recognize the connected Slave.
For this purpose, the Slave instrument must be defined as "Real value
correction". Select under the menu item "Setup/Application" the func-
tion "Real value correction".
You can set the address (MGC) on the Slave instrument at will. Only
the address "0 - 0" is reserved for the Master instrument.
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".
You have to enter the address of the Slave instrument in the list of
the Master instrument. This function is not possible in the display and
adjustment module. To do this you need PACTware with the respective
DTM.
The main menu is divided into five sections with the following func-
tions:
Setup: Settings, e.g. for measurement loop name, isotope, applica-
tion, background radiation, adjustment, signal output
Display: Settings, for example language, measured value display
