RDS-32 FUNCTIONALITY

3.11.3 PROBES WITHOUT INTERNAL MEMORY
The RDS-32 is compatible with some probes which don’t have internal memory, the most
common being the GMP-11-3 pulse rate probe, the GMP-15-3 pancake probe, the GMP-12SD
dose rate probe with high dose endurance.
When connecting a probe with no memory, the user will be prompted first to select the probe
type. There are three types:
• Gen.CHK.Def is for a probe with no internal memory that is tested for the pulse
generation of the external probe. If no pulses are detected for a given time, the meter
will show an error message. Select this type when using GMP-11-3 or GMP-15-3.
• Gen.No.Def is for a probe with no internal memory that is not tested for pulse
generation. For example, probes which are alpha sensitive only, and there are no
pulses at all in the determined time window.
• GMP-12SD is dedicated to the GMP-12SD dose rate probe. When using this probe
type, select first the probe type and then the probe serial number to use the correct
probe calibration coefficients. If the serial number is not selected, probe type default
coefficients will be used. If the serial number is not available, the probe calibration
coefficients have not been saved into the RDS-32 memory. The CSW-32 Configuration
software is required to do that. See the software manual for instructions on how to
save the probe coefficients.
The probe type can be changed without switching the meter off, by navigating into the PROBE
menu and selecting another type. Selecting the wrong probe type may lead to an error
condition Det.DFE accompanied by an audible alarm, as the pulses from the probe don’t
match to the expectation and the meter detects a detector fault. In this case, switch the meter
off and select another probe type at start up.
