When the values "Level 1" (low oxygen concentration) are reached, the light, vibration alarm,
sound with a pressure level of 95 dBA is triggered through the O2 channel. It is not possible to turn off
the forced alarm, all types of alarms are switched off when the concentration of the measured gases
exceeds the threshold "Level 1".
When the values "Level 2" (high oxygen concentration) are reached, the light, vibration alarm
and sound with a pressure level of 85 dBA are triggered through the O2 channel. Sound and vibration
alarm can be turned off by briefly pressing the button. The indicator will continue to flash the oxygen
concentration value, the light alarm will reduce the flash rate by 5 times. All kinds of alarm is
automatically disabled when returning the value below the "installation Level 2»
2.3. Embedded device clock
The device contains internal clock for the implementation of the binding concentration of the
measured gases at the time of the measurement when you save to the internal memory. The clock time
is automatically adjusted when reading data from the internal memory to an external device. The clock
is not displayed on the device.
2.4 The remaining time of operation of the device
The device is equipped with the function of displaying the remaining operating time. This function
monitors the operating parameters of the device, the number of this alarm, the temperature conditions
of operation of the device, etc. to predict the remaining operating time of the device. The initial
calculation is made from the conditions: the ambient temperature of 25 C, the total time of the alarm
during the day does not exceed 2 minutes. Indication of the remaining operating time is carried out in
weeks (indicated by the symbol WK) until the end of the device, or as a percentage of the entire life of
the device (indicated by the symbol %). During the "sleep" mode to extend the life of the device, the
ability to trigger the alarm and write data to non-volatile memory is disabled.
2.5. Built-in device memory
The device is equipped with a built-in non-volatile memory to store the concentration of measured
gases with time reference. In the memory of the device can be stored about 11000 records about the state
of the atmosphere. The time between data recording to the device memory can be set from 15 seconds
to 3600 seconds.
