TESTING MODE
The device enters this mode just after switching on.
Before the beginning of the testing process the indication (sound and/or vibrating) is switched on
approximately by 1 s. All marks, segments and pointers must be indicated on the LCD.
Then on the LCD a number of the software version (P-1.4) is indicated on the LCD for
several seconds.
In the testing mode all required tests are fulfilled. Initially, the battery
discharge level is tested. “bAtt” is indicated on the LCD, as well as quantity of
segments of the analogue scale which corresponds to the battery discharge level.
Then the “test” message is indicated and the reducing analogue scale. Tests are
performed. The time to completion of the test is displayed in relative units on the
analogue scale in the form of the reducing number of the indicated segments.
After the test completion the device is shifted to the calibration mode by the
background level. The analogue scale is indicated on the LCD with the number of
segments increasing in time, as well as the message “

.
CALIBRATION MODE BY BACKGROUND LEVEL

The indicator enters this mode automatically after completion of the testing mode, and being so,
“CAL” message is indicated on the LCD
In the calibration mode the analysis of the background level of gamma (and
neutron) emission is carried out.
Attention! Find below the principles of operation of the device gamma channel.
Functioning of the neutron channel

is subordinate to a more complicated operation algorithm and
is not shown in details in the present manual.
The processor counts the number of impulses passed from the detection block over the preset
calibration time, and the time is indicated on the analogue scale in relative units from the calibration
beginning in the form of increasing number of the indicated segments. In case of recalibration of the
indicator by the user during operation the recalibration time may automatically be reduced along with
growth of the background level, when calibration is fulfilled.
