  • Page 25: Zero Sensors

    What is zeroing? If G7 is not reading zero and you know you are in an atmosphere with no gas, your gas sensor readings may have shifted. If this happens, it is best to calibrate your sensors. If you are unable to preform a calibration, you can zero your sensors to reset the baseline.

  • Page 26: Gas Alert Countdown

    In both of these places, G7’s screen will display the target gas’ name, as well as its correction factor. GAS ALERT COUNTDOWN This feature will make it easier to prevent false alarms from being delivered to monitoring services. Gases like CO and O2 can spike and dip very quickly, setting G7 into high gas alarm even when gas levels go back to normal.

  • Page 27: Using G7 Sensors In Cold Weather

    Countdown. USING G7 SENSORS IN COLD WEATHER G7 is rated to operate down to -20°C (-4°F). G7 will function in temperatures colder than this for short periods of time, but Blackline does not recommend letting the device’s internal temperature drop below -20°C (-4°F).

  • Page 28: Gas Alarms And Alerts

  • Page 30: Red Alert Gas Features

    SHORT TERM EXPOSURE LIMIT (STEL) ALERT An alert will be triggered when G7 detects you have reached the STEL configured by your safety supervisor. STEL refers to the gas concentration that you can be continuously exposed to for a configurable time frame without suffering adverse health effects.
  • Page 31 NOTE: STEL, LEL and peak readings are reset on power cycle. To have G7 resume readings instead, this setting can be configured in G7’s configuration profile in Blackline Live. What do I do in the case of a red alert? Evacuate the area and follow your emergency safety protocol.

  • Page 32: Configuration Modes

    Configuration modes are customized in the G7 configuration profile on Blackline Live. Each profile supports up to a total of five modes. These modes allow G7 to temporarily change its behavior for different situations, and can be turned on and off through G7’s interface.
