Page 5: General Setup And Functions
Part 1 General setup and functions 1.1 Safety instructions • Do not modify the electronics of AC-powered devices. Before starting the instrument ensure hardware integrity. • The product is a high voltage device. In operation the amplifier, the cables and connectors to the proportional counter tubes can carry high voltages above 1000 V.

2.1.2 Sensor start • Switch on the device by setting the main power switch to the ’On’ position. The status display shows the StyX Neutronica logo. • The logger checks whether there is an SD card inserted. – If yes, it checks the existence of a correct configuration file central.cfg with the correct revision in the root folder and whether the configuration file should be used.

On the status display the sensor start procedure iterates through the following panels: Step 1 Step 2 Step 3 Step 4 Step 5a Step 5b Step 6b Independently from the logger boot process the nCatcher is initialized with the following steps: •...
Page 11 • the number of cycles for averaging GPS values before storing them to the SD card. • the number of cycles for recording neutron data before saving histograms to the SD card. Due to the low bus speed SDI-12 sensors are not read out every cycle but once every averaging interval. The status display can be switched through several panels Panel 2 Panel 3...
Page 12: Service And Transport
2.1.4 Service and transport The sensor can be transported by means of usual spring-suspended transport devices. For transporta- tion an anti-shock mat is recommended. Dropping down a tube on a hard surface from heights more than 10 cm can lead to damages. 2.2 Software configuration The configuration file central.cfg in the main folder of the SD card contains the following settings 1 // use this config file [bool]...

Page 14 • threshold: The amplifier features a hardware threshold for setting a lower limit for signal detection. It spans 4096 values. Setting the threshold in the range 1–4095 is a non-permanent adjustment, the range 4096–8192 writes the value to the internal nCatcher EEPROM memory. In that case this value is restored after a bootup or a power loss.
