POINTRAC 31 • 8/16 mA/HART - four-wire

39411-EN-131119

The POINTRAC 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.

Setup

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",

"X-ray alarm" or "Real value correction".

X-ray alarm

ing result of continuously measuring, radiation-based sensors.

You can also use the POINTRAC 31 as a Slave instrument for detec-

tionagainstX-rayalarm.Henceanalarmcanbetriggered.

For this function you require PACTware with the respective DTM.

Real value correction

detectionofadenedlevel.Henceyoucanautomaticallycorrectthe

measured value of a continuously measuring, radiation-based sensor

to the real value when this level is reached.

For this function you require PACTware with the respective DTM.

urement.

With this menu item the natural background radiation can be faded

out.

For this purpose, the POINTRAC 31 measures the natural back-

groundradiationandsetsthepulseratetozero.

In the future, the pulse rate from this background radiation will be

automatically deducted from the total pulse rate. This means: only

the component of the pulse rate originating from the source will be

displayed.

The source container must be closed for this setting.

In this menu item you can select the temperature unit.
