Autonomous Monitoring Mode

  • When the sensor is placed in autonomous mode the sensor will beep once.
  • If no commands are given, the sensor will beep twice and begin scanning after 20 secs.
  • To enable the menu functionality in autonomous mode, type MENU within the first 20 secs of power up and the sensor will beep three times.
  • To enable scanning after menu functions are complete, repower the sensor.
  • If MENU instruction has not be given in the first 20 secs the sensor will not respond to any instructions and will continue scanning regardless of any commands given.

The Autonomous Mode Primary Menu looks like this:

SYSTEM FUNCTIONS:
VERSION ----- Display the sensor firmware revisions, serial number and time

Measurement Functions

IMMERSION

This function allows you to enable or disable the immersion sensor. The immersion sensor will need to be disabled if testing the sensor in dry conditions.

The following will be displayed:

Please select 1 or 2 [ENTER]

1 = Enable immersion sensor
2 = Disable immersion sensor

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
