Identifying Parts - SEEIT TM-91N Manuel D'utilisation

Safety precaution before use:
This manual contains valuable information about the nature of ionizing radiation that should be understood by the user so that
accurate measurements can be made. Information on the care of Geiger counter is also included. If the following instructions are
followed, your radiation monitor will give you many years of reliable service. The radiation meters are very sensitive pieces of
equipment. Although housed in a high-impact case, the Geiger Mueller tube that senses radiation is fragile. If the unit is dropped, the
G-M tube may break. Exposure of the unit above 40°C (100°F) may also cause the G-M tube to stop functioning. The electronic
circuitry is sensitive to high humidity (over 90% RH).
Warning :
Take extremely care of the following conditions while
measuring.
Please put the radiation monitor into a plastic zipper bag
before operating it in a radioactive contaminated area to
