1. Introduction 1.1 RDS-31iTx S/R Multi-Purpose Survey Meter The new RDS-31iTx S/R Multi-purpose Survey Meter continues the line of the Mirion survey meters offering modern design and approach to a wide range of radiation monitoring applications. RDS-31iTx is a small hand held, battery-operated survey instrument utilizing an energy-compensated GM-tube as a primary detector.
RDS-31, additionally the GMP-12 series gamma probes and the GMP-11/GMP-15 alpha/beta/gamma probes of Mirion Technologies (RADOS) Oy. In addition, the TGS gamma contamination, Alpha Wound and Alpha 125 alpha contamination probes from Mirion Technologies (MGP) of France can be connected to RDS-31.

The instrument uses two IEC (LR6/ HR6) AA-size batteries. The use of alkaline batteries is recommended, but rechargeable NiMH batteries can also be used. The polarity of the batteries can be seen in the picture below. It is also engraved in the bottom of the battery compartment. Insert the batteries and secure the battery cap.

3.2 Connectors and Strap The connector for an external detector and an external charger is in the bottom of the instrument. There is also the fixing lug of the wrist strap. The round connector (Binder 702 series) is used for external probes, for cable connections and for external alarming devices.
to prevent any unwanted activation of the button e.g. while wearing gloves. The two buttons have been named On/Off [ ] and Menu [Ξ]. This indicates the main purpose of the buttons. The On/Off button switches (through the menu selection) the instrument on and off.
on for 24 seconds and the Menu button would give the current accumulated dose in the display for 14 seconds. In the background, the instrument would perform the diagnostics and record the current status, dose and dose rate into the histogram memory with each pushing of the button (Manual histog.

The instrument starts measuring the dose rate and accumulating the dose immediately when the instrument is switched on. During the initial start-up, the instrument informs the user that the time of the Real Time Clock has not been set (flashing ‘TIME NOT SET’...
5.3 Operating the Instrument Menu The actual Menu list is completely dependent on the existing instrument configuration. This means that in the most basic form there are no items in the menu list that can be activated with the button operations. Pressing the button will only illuminate the display and perform some internal functions.
1) Optional menu items depending on the configuration 5.4.1 Show and Reset Cumulative Dose (DOSE) The instrument integrates the cumulative dose continuously into a dose register when switched on. To see the cumulative dose: Activate the menu (Short [Ξ]) and scroll (Short [Ξ]’s) until display changes to DOSE.
Press an intermediate [ ] (Short [Ξ] takes back to the menu). The maximum dose rate is now set to zero. The display shows the 0.0 µSv/h (0 µrem/h) without blinking and if no button actions take place within the time-out period, the display returns to the dose rate.
To change the chirp state: While the current chirp state is displayed, press [ ]shortly and the display shows the state of the related Chirp function blinking Scroll with short [Ξ] until the desired value (CA:OFF| CA:ON; CV:OFF| CV:ON; CH:/1|…CH:/50) is given ...
5.4.4.1 Fixed Dose Rate Alarm Level: There are 8 different levels for dose rate alarm: disabled, 10, 50, 100, 500, 1 000, 5 000, 10 000 or 50 000 µSv/h or mrem/h. The user may select any one of these to be the active alarm threshold level.
5.4.4.2 Sequential Dose Rate Alarm: When sequential dose rate alarm function is enabled, all the eight dose rate alarm levels will be active in the order of the list (the default values are the same as in the “fixed dose rate alarm level”).

display changes to FX.DAL The current dose alarm threshold value is displayed on right side of the display. To change the current dose alarm level: While the current dose alarm level is displayed, press [ ]shortly; the next level in row starts blinking ...
5.4.5.2 Sequential Dose Alarm: NOTE: the sequential dose alarm function can be taken into use with the CSW-31 Software only! When the sequential dose alarm function is enabled, all the eight dose alarm levels will be activated in the order of the magnitude (the default values are the same as in the Fixed dose alarm).
To check the status of the Time to Dose Alarm: Activate the menu (Short [Ξ]) and scroll (Short [Ξ]’s) until display changes to TM.2.AL The current status is displayed (the remaining time to reach the current dose alarm level in form of xxh xxm or disabled = DISAB).

adapter is activated and remains waiting the RDS-31 instrument to be connected to the adapter. When the Cable-adapter to the PC–link is established and the instrument is connected to the adapter, the communication between instrument CSW-31 activated automatically. When the RF-adapter to PC–link is established, the instrument is manually set to start the communication.
5.4.9 Histogram (HISTO) The Histogram functions of the RDS-31 are very versatile. The menu functions of the Histogram are summarized in the following table. First HISTO level Second STATE L: (location) I: (interval) Manual Clear level Third Show the Show the Show the Picks Clears the...

The histogram function of the user interface has the following main features: STATE: The STATE provides the currently active status of the timed histogram logging. When ON the measurement data is stored into the histogram memory using the determined interval.
Page 32
Manual: It is also possible to store manual samples into the histogram memory. In this case, only the immediate value in the display is stored. With timed logging, the average and maximum dose rate values are also stored. Clear: ...

Res/h 0,01 Dose Rate [µSv/h] Typical result for the RDS-31 standard GM-detector and counting statistics, not to be used as a specification. 5.4.9.1 Other Histogram Records In addition to the preprogrammed and manual histogram data storing, there are automatic records that are stored into histogram memory: ...
Calibration memory: results newest calibrations are stored in the memory. The oldest are overwritten in case more than 64 calibrations are performed. Diagnostics memory: The first start-up of the day is stored here. In case the instrument operates continuously without going to the OFF state, an automatic diagnostics is run at 00:00:00 and the results are stored into a specific diagnostics memory.

With CSW-31 LITE there can be one Shortcut to the menu button ([Ξ]) only. With the CSW-31 PRO, the user can configure two shortcuts to both buttons ([ ] and [Ξ]) allowing up to 4 different choices. Note: To avoid confusion and misuse of instrument, the user should check with the CSW-31 software the programming of the Shortcut.
Page 36
Diagnostics The menu item DIAG is activated. The normal button operations are allowed from this point forward. Note: In case the instrument configuration would not allow the function that is programmed into the Shortcut, the Shortcut function overdrives the instrument configuration. This means that even in a case where the instrument menu is completely disabled, some limited actions can still be performed using the Shortcut function.

6.2 Show and Reset Cumulative Dose (DOSE) The cumulative dose is always measured from the internal tube, even when using an external detector. The dose alarm can therefore be used to warn the user even when using any type of an external detector. The dose is accumulated always when the instrument is switched On.
cannot be changed using the instrument’s push button. Configuration 3: The Alarm Level is displayed and can be changed using the push button. 6.5 Show and Change Dose Alarm Level (FX.DAL/SQ.DAL) The Dose alarm is always measured from the internal tube even when an external detector has been inserted.
Configuration 2: Manual diagnostics is allowed. 6.8 Histogram (HISTO) The histogram function stores the dose and dose rate information into the memory for later analysis. The storing of the data can be manually activated or time sampled. Each data set consists of all the measurable data available and, the user can activate what data is to be processed through the filtering options during the read-out.
6.9 WRM transmission The RDS-31iTx model has an extra radio modem which can be used for transmitting the dose/dose rate data to a master system at selected time intervals. Option Effect Configuration 1: Disabled Configuration 2: Enabled 6.10 Indication Unit The displayed units can be chosen between Sv and rem.

Note After fitting fresh batteries, it is recommended to perform the functional test (DIAG). If the flashing low battery symbol appears in the display after the test, refit the batteries. Note: When changing the battery type between alkaline and rechargeable, use the CSW-31 software to indicate the change to the instrument.
