Operation Manual

Battery and Power Supply

GAMMA-SCOUT

is powered by a 2.7 - 3.7 V lithium thionyl chloride cell. The device will continue

functioning until the cell voltage is down to 2.8. When the voltage drops below this value, the batte-

ry symbol will appear in the display. The data will be retained, even following a total loss of voltage.

The RECHARGEABLE model has a rechargeable battery, which can be recharged via USB (or the

power supply unit included with delivery).

Displaying the Battery Voltage

Press the button to display the current battery voltage. The display shows the remaining

voltage available minus the load drawn by the built-in electronics.

Displaying the Software Version

Press the button while the battery voltage is displayed, the display briey shows the software

version.

Changing the Battery

The battery is permanently xed to the circuit board (because of our extremely low currents of

approximately 10 microampere, plug-in batteries would constantly lead to current interruptions due

to oxidation on the contacts). Should the user want to solder in a new battery, the initial settings can

be restored by pressing the reset button. However, please be aware:

Opening GAMMA-SCOUT

cancels the warranty.

Reset button

The device can be restarted by pressing the reset button (next to the opening for the USB interface,

at on the circuit board). This changes time and date back to factory settings.

Ticker (not in the basic model)

A double click of the button will display the word “on” – which means that the ticker can now

be switched on. Pressing the button will switch on the ticker and a “speaker” symbol appears in

the display. If the ticker was already on, the word “off” would appear in the display and pressing the

button would switch it off. The “speaker” symbol would then disappear.

With the ticker is switched on, GAMMA-SCOUT® emits a tone with each pulse. Increasing radiation

will cause single tones to become a cascade. The tones use 500 times more power than normal

measurement does under environmental conditions. Therefore, the ticker switches off automati-

cally after 10 minutes. If the ticker is used once per day, the power consumption remains within

the acceptable service life of the battery. If the ticker is used more often, the battery will last for a

shorter period. In this case, a maintenance fee will be charged for a battery change. Number and

duration of ticker use is logged internally. On rechargeable devices, the timer does not switch off

automatically.
