INDICATOR OPERATION
Attention! In case of the indicator operation at temperature below minus 15 °°°°
С
normal
operation of the LCD is not guaranteed. In this case only sound or vibrating indicators should be used
as the source detecting indicator. When the indicator returns to the conditions with the temperature
above minus 15
°°°°
С
the normal operation of the LCD is restored.
INDICATOR SWITCHING ON/OFF
For switching the indicator ON in the process of operation the MODE button should be pressed.
Immediately after switching on the LCD illumination must be switched on
and all LCD segments must be illuminated at the same time approximately for 1 s
signaling (sound and/or vibrating) must be switched on, the device must be shifted to
the testing mode. In the testing mode a number of the software version (P-1.4) is is
indicated at the LCD for several seconds.
After completion of the tests the indicator must be shifted to the calibration
mode by the background level
(
except for devices having the search mode "0-9"
)
, the
analogue scale is indicated on LCD with the number of segments increased in time,
as well as the “
СА
L” message.
After calibration completion the indicator must be shifted to the working mode in accordance with
the order chart (see attachment A).
The indicator is ready for operation.
For switching off the indicator a LIGHT button is to be pressed and kept for more than 5 s. Being
so, the "
OFF
" appears.
Attention! The indicator is automatically switched off (“OFF” is indicated
at the LCD) after reading the indicator operation history in the mode of
communication with a PC).
OPERATION MODES
Operation modes included by the manufacturer in the given indicator modification comply with
the order chart (see attachment
А
).
The indicator provides the following operation modes:
• the testing mode;
• the calibration mode by the background level;
•
the searching mode (indication of the average count speed, s
-1
);
• the mode of MED measurement;
•
the mode of MED measurement along with the search function;
•
the searching mode "0-9" (indication of digits 0-9);
• the mode of gamma registration
(only for РМ 1703 М - О 1)
• the mode of indication of the average count speed of gamma radiation over the time of
accumulation
(only for РМ 1703 М - О 1)
