The LCD screen may display any of the following information:
• gamma Dose Rate (DER) in µR/h;
• Dose (DЕ) in µR;
• n coefficient: number of mean square deviations for the gamma threshold (also called “alarm
multiplier”);
• Messages "tSt", "CAL", "OL", "oFF" etc.;
• “ ” sound alarm icon (if sound alarm is enabled);
• “ ” vibration alarm icon (if vibration alarm is enabled);
• Blinking “h” symbol — indicates that there has been an alarm actuation and information about it
hasn’t been uploaded to a computer;
• Blinking “S” symbol – indicates that the search mode is currently on;
• Critical battery discharge: displayed when the battery voltage drops below 1.15 V.
An analog bar in the lower area of the LCD display indicates the time left until self-tests or background
calibration are completed.
In the Search Mode, Measurement mode and Dose indication mode, the analog scale segments represent
the dynamics of radiation environment change. The bar represents a relative excess of the measured
value over the set alarm threshold.
