1. PRESENTATION
The STTC probe is intended for the measurements of the ambient equivalent dose rate for gamma
radiations. It can be connected to any CSP survey meter via the appropriate connection cable. It allows
to widen the measure dynamics of the device and to run remote measurements up to 20 meters. It
comes under the shape of a compact and sturdy metal case which contains the Geiger-Müller detector,
the high voltage supply and the pulses shapers.
Due to its wide range of measure, it can be used in nuclear power plant to control very variable gamma
streams, but also in medicine or in emergency situation (measure after accident, fire brigades). It is also
possible to use this probe in measure of environment, combined with a remote communication device
CSP-COM, if the measure of the background is not exactly required.
STTC-W is the waterproof version of STTC. It includes a 20 meters cable on a reel and ballast. STTC-
W cable is mounted on probe body via a cable gland to ensure good waterproofness down to 40
meters.
The STTC probe can be connected to CSP survey meters and radiameters such as :
-Avior 4000 with a firmware version 1.08 or superior,
-Radiagem 4000 with a firmware version 4.22 or superior,
It can also be connected to a PC :
-equipped with CSPS Software version 2.0 or superior,
-equipped with a software using CSP-PL ™.
Note: the new versions of the firmware can be downloaded for free on the Canberra website:
www.canberra.com. See the user manual of the survey meter for the complete update procedure.
For connecting the probe to the CSP-COM, an aluminium adapter ring is provided.

3. PROBE FUNCTIONING
3.1. UNITS DISPLAY
Rem/h for all the CSP survey meters; Rem for compatible survey meters (see user manual).
3.2. IDENTIFICATION OF THE PROBE FUNCTIONING MODE
The type of probe connected is shown on the survey meter display.
3.3. ALARM SET POINTS
The new STTC probes are delivered with 10 values for each unit with default setting stored in their
memory. They can be changed by connecting the probe to a computer with CSPS (Canberra Smart
Probe Software). Selection of the active alarm set point (used for the alarm triggering) is done on the
survey meter.

3.4. PROPER DETECTOR FUNCTION TESTING
The survey meter continually checks to ensure the detector registers a minimum count rate (due to the
background and the genvironment). If no pulses are detected within 180 s for STTC, the system
indicates there is a detector defect by displaying “FAIL” and by sounding 1 audible beep every
10 seconds.
3.5. PROBES PARAMETERS SETTING
The STTC probes parameters setting is performed through a direct link to a PC (USB connection, cord
78466).
The Calibration/Setup software (CSPS) enables to define equivalent activity coefficients, to calibrate the
probe under QA procedure, to modify the probe alarm set points and to download data from probe
memory to PC via a USB cable.
3.6. DATA LOGGING
The probes can store in their memory up to 1000 data stamped measurement points whom the date
and time are written by the connected instrument.
The recorded data are structured as follow: Index, Date, Time, Measurement, Unit, Measurement time.
The unit which is displayed depends on the user selection during the probe connection to the
instrument (§ 3.1).
The data logging running and measurement time setting are performed by the instrument connected.
The data download is performed with CSPS through a direct link to a PC (USB connection, cord
78466).

4. USE
4.1. CONNECTING THE PROBE
For the survey meters:
-Connect the probe to the survey meter via a 1,50 m cable (code 77336) or a 20 m cable (code
80653).
Example of a STTC connected to a RADIAGEM
A probe can be connected to the CSP surveymeter even if it is switched on. The host instrument
automatically detects the presence of a probe, if the cable is first connected to the probe and then to the
surveymeter (e.g.: Radiagem).
For the PC equipped with CSPS:
-Connect the probe to the PC via the cable code 78466.
4.2. CONNECTING THE STTC-W PROBE
For the survey meters:
-Connect directly the probe to the survey meter as shown below:

For the PC equipped with CSPS :
-Connect the probe to the PC via the cable code 78466.
4.3. DISCONNECTING THE STTC PROBE
The probe is equipped with a locking connector, for disconnecting the cable from the probe :
-Pinch the probe side connector between thumb and forefinger,
-Pull on the connector to unlock it and simultaneously pull the cable side connector.
4.4. CONNECTING THE STTC TO THE CSP-COM
The aluminium ring provided with the STTC is necessary to connect the probe to the CSP-COM.
