RDS-32 FUNCTIONALITY
36
The Probe Unit menu shows the probe measurement unit which is currently in use and allows
the user to change the unit. For the GMP-25 probe the available units are cps, cpm, dpm, Bq
and Bq/cm2. To change the measurement unit, navigate into the Probe Unit menu and select
from the list. Note that when selecting Bq or Bq/cm2, the conversion from counts to Becquerels
will be made using the isotope coefficient introduced in the next paragraph.
The Probe Isotope menu shows the name of the current isotope coefficient in use. To view
the actual numerical coefficient or to change the isotope settings, use the CSW-32 software.
When using the ABP-150 probe, the Probe menu features also the radiation type selection -
alpha or beta.
The RDS-32 reads data from the probe memory such as the unit of measurement and the
saved isotopes. For example, the default unit in the GMP-25 is cpm. Even if the unit is changed
from the meter menu, at the next power on the cpm unit will be read again from the probe
memory. The CSW-32 software allows the user to create isotope profiles where the default
unit can be changed, and several isotope coefficients can be saved. These profiles can be
uploaded to the probe memory. The isotope in use (for GMP-15 or ABP-150) can then be
selected from the meter menu. See the CSW-32 Software manual for more details.
