Starting the Logger

It is highly recommended you start a UTRED30-WiFi logger only after you have placed it in the position it will be used in. This allows you to verify wireless and network connectivity on site quickly after the start.

Push button start

After configuration for a push button start the current time and READY are shown, together with the Backup Battery Status symbol.

The power symbol is shown when the unit is connected to a USB power supply.

WiFi and cloud connection symbols are also shown with a tick, if the UTRED30-WiFi successfully connected to the wireless network directly after configuration with LogTag® Analyzer.

Ready to be started

Press the START/CLEAR/STOP button. Starting is briefly shown in addition to Ready.

Start Sequence

Then Ready disappears.

Start Sequence

Once Ready disappears, release the button within two seconds. Starting will now disappear, and the Recording symbol will be shown. The UTRED30-WiFi now records temperature data.

 

The logger will not start if you…

  • release the button before Ready disappears
  • keep holding the button for more than 2 seconds after Ready disappears.
  • The backup battery is critically low and the logger is not connected to power.

Recording OK, no alarms

The UTRED30-WiFi now automatically performs a Connection Test (see Testing your wireless and network connection).

Push Button Start with Start Delay

If the logger has been configured for a push button start with a start delay, the word STARTING deLay is shown instead of  the Recording symbol.

The delay time is shown in hours and minutes. The time counts down and the UTRED30-WiFi starts recording when it reaches 0:00.

The WiFi connection symbol is shown with a tick, if the UTRED30-WiFi successfully connected to the wireless network directly after configuration with LogTag® Analyzer.

As with a regular push button start without delay, the UTRED30-WiFi will perform a Connection Test as soon as the recording has started. To check the connection before the delay value has elapsed, you can initiate the connection test yourself. Please refer to Testing your wireless and network connection (on page 1).

The timer can be cancelled and the logger reset to Ready.

While Starting and Delay are shown, press and hold the START/CLEAR/STOP button. Stopped will now show. Release the button when Starting disappears.

Stopped and Delay will both disappear, and Ready will show, together with the current time, and the logger can now be started again as normal.

The UTRED30-WiFi will not be reset if you …

  • release the button before Starting disappears, or
  • if you keep holding the button until Stopped disappears.

Cancelling the timer

Automatic date/time start

If you configured the UTRED30-WiFi for a date/time start, it will start recording temperature values as soon as the entered start time is reached. Until then the logger will display the screen on the right.

Once the configured start time is reached, the logger shows the normal recording display.

Waiting for a Date/Time Start

The UTRED30-WiFi will perform a Connection Test as soon as the recording has started. To check the connection before the start time is reached, you can initiate the connection test yourself. Please refer to Testing your wireless and network connection (on page 1).

Hibernating the logger using LogTag® Analyzer will abort any previously configured Date/Time start.
