MINITRAC 31 • 4 … 20 mA/HART - four-wire
40447-EN-131119
Start with the setup of MINITRAC 31.
In the main menu point "Setup", the individual submenu points
should be selected one after the other and provided with the correct
parameters to ensure optimum adjustment of the measurement. The
procedure is described in the following.
Stick with the normal sequence of the menu items as closely as pos-
sible.
Setup
In this menu item you can assign an unambiguous name to the sen-
sor or the measurement loop.
This parameter is described in the operating instructions manual
"Display and adjustment module".
In this menu item you can adjust the MINITRAC 31 to the integrated
isotope in the source container.
For this purpose, check which isotope is integrated in the source
container. You can find this information on the type label of the source
container.
Through this selection, the sensitivity of the sensor is adapted
perfectly to the isotope. The normal reduction of the emitter activity is
hence considered through the radioactive decay.
The MINITRAC 31 requires this information of the automatic decay
compensation. This ensures an interference-free measurement over
the complete life time of the gamma emitter - an annual recalibration
is not necessary.
Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.
Enter here, the respective application.
This menu item enables adaptation of the sensor to the requested ap-
plication. You can choose between the following applications: "Level",
"Density", "Limit level", "X-ray alarm" or "Real value correction".
