WELCOME
Thank you for purchasing a Polimaster Gamma Personal Radiation Detector
PM1401MA. Before operating this unit, please review this manual thoroughly and retain it for
the future references.
PM1401MA is designed to detect, search, and locate gamma radioactive sources.
PM1401MA uses Infrared (IR) interface to communicate with a personal computer.
The instrument is easily operated and requires only understanding of the basic
parameters and settings for proper operation.
PRECAUTIONS
• The PM1401MA is not a personal safety device. It is designed only for the detection
of radiation sources and does not function as a personal dosimeter.
• Keep the instrument at least 11 cm (4 in.) from radio emitting sources, such as cell
phones, to avoid false positives.
• Do not store the instrument with battery installed. The battery will leak once
depleted causing severe damage to the instrument and void the warranty.
• Do not expose the instrument to high temperatures. Environment operation
temperature range of the instrument shall be above -30 °C (-22 °F) and below +50 °C (+122
°F).
• Avoid severe mechanical shocks and submerging the instrument into water.
