4.3 Measurement Modes for the Scintillator Probe.

Following initialisation – see previous section - the user may choose to change the measurement unit mode. The

various measurement modes for the scintillator probe are:

 cps count rate (or cpm)

 background subtracted cps count rate (or cpm)

 Dose rate in µSv/h (or µR/h)

 background subtracted dose rate in µSv/h (or µR/h)

In each case it is possible to utilise the integration function whereby the displayed reading is averaged over a

period of time.

Note: The NORM Monitor-IS is capable of displaying SI units as well as non-IS units (primarily US market). Cps or

cpm & Sv/h or µR/h are factory set parameters and not configurable in the field.

4.3.1 cps Mode

Press the mode

key until the “cps” text appears on the LCD display as shown.

Figure 5 - cps readout screen

This screen provides a bar graph and digital display indication of the radioactivity detected by the probe in counts

per second (cps).

In cps mode the value displayed indicates the total count rate detected by the probe and includes any contribution

from environmental background radioactivity.

The green indicator LED will flash whilst the instrument is counting in this measuring mode
