Autonomous Monitoring Mode

To access autonomous monitoring mode​

To start/stop sensor scanning​

  • when the sensor is powered up it will beep twice
  • in autonomous mode, if no commands are given within 15 secs, the sensor will beep twice again and begin scanning
  • the first sensor readings are provided after 3 mins
  • to stop scanning, remove power to the sensor
note

Unless in modbus mode, once scanning in autonomous mode, you cannot access the menu functions unless you power cycle.

To display the sensor output on anb_utils​

  • open anb_utils
  • turn on the sensor, and wait for the second beep
  • select the com port within 15 secs
  • select the command line prompt (option 3) on anb_utils and the splash screen will be displayed
  • type mode from the primary menu and select option 2
  • recycle power to the sensor without closing anb_utils
  • if no commands are given within 15 secs, the sensor will beep twice again and begin scanning
  • the sensor output will be displayed after 3 mins
  • to stop scanning, remove power to the sensor

To access the Autonomous Primary Menu​

  • open anb_utils
  • turn on the sensor, and wait for the second beep
  • select the com port within 15 secs
  • select the command line prompt (option 3) on anb_utils and the splash screen will be displayed
  • type mode from the primary menu and select option 2

Measurement Functions​

INTERVAL​

This function allows you to choose the time (H:MM) between measurement blocks with a minimum of 15 minutes (0:15) and a maximum of 4 hours (4:00).
Should you require continuous measurements, simply enter 0:00.

note

The sensor will go into a low power state during the set interval.

The following will be displayed:

To add Interval Time please enter H:MM [ENTER]

where H(Hours) = 0 to 4
where MM(Minutes) = 15 to 59

With a MINIMUM time of 15 minutes
and a MAXIMUM time of 4 hours

For no Interval enter 0:00

START DELAY​

This function changes the time delay before monitoring starts, with a minimum of 0 minutes (00:00) and a maximum of 24 hours (24:00).

To add Start Delay please enter HH:MM [ENTER]

where HH(Hours) = 00 to 24
where MM(Minutes) = 00 to 59

With a MAXIMUM time of 24 hours

For no Start Delay enter 00:00
