A fully graphic LCD with switchable illumination (LED back-light) shows all the information. Four keys allow to select functions from a menu, where the display always describes the current function of all keys. Menu options are represented in plain language. The user may select one of the three pre-programmed languages (German, English, French) or even a fourth individually programmable language. Besides the current function the display always shows some important parameters in a status line: battery condition, detector in use (low or high range tube), date, time, and whether alarm thresholds have been exceeded.
The Teletector can store up to 450 measurements. One measurement is not just a shot of the current dose rate, but it is an averaged value of dose rate, where the user can control the averaging time. This permits improved statistical accuracy of the stored measurements especially at low dose rates.
The integrated loudspeaker allows single pulse detection and sounds when some alarm is on. In case of contamination, the speaker may easily be replaced without having to open the instrument.
A non-volatile memory stores all settings when switching the Teletector off or when replacing the batteries. The real time clock keeps date and time with the help of a rechargeable back-up battery. A 16-bit microprocessor controls all the functions.
The Teletector 6112M(/H) has three operational modes the user can select:
6112M mode: This mode offers the widest scope of functions.
6150AD mode: This mode makes operation very similar to operating a 6150AD5/6. Only the 6150AD5/6 functions will be available..
Fire brigade mode: In this mode the Teletector only indicates dose rate, other functions are not available. The dose rate alarm threshold is fixed at 25 µSv/h. This mode is particularly intended for use by fire brigades.
