  • Page 112 Configuration menus LoRaWAN wireless range test You may use the range test feature in the Advanced menu to ensure that your Cobalt X data loggers are within wireless range of the configured LoRaWAN network (i.e. your LoRaWAN gateway). This feature is useful for system installers, as it can help you prepare your environment before deploying Cobalt X data loggers.
  • Page 113 Configuration menus We recommend not setting up your data loggers if signal level is weak. Poor signal quality can result in inadequate coverage and cause system performance or reliability problems. The wireless signal may be affected by excessive obstruction, RF/radio interference, or harsh environmental conditions. Make sure the data logger in question is placed optimally long-term operation.

  • Page 115 Configuration menus 7.4 Quick server connection test Without using the Advanced menu, you may perform a simple Test command to make sure that your Cobalt X data logger is able to communicate with the server. This function sends a request to the server and waits for a response to determine whether the server is reachable.
  • Page 116 Configuration menus 7.5 Data synchronization The OCEAView monitoring solution enables you to force synchronization of your Cobalt X data logger with the server. This may be useful to speed up certain operations, notably: • When adding a new sensor to a Cobalt X data logger: if you use the Synchronize function, the new sensor is updated on the server right away, otherwise the update occurs at the next programmed data transfer.
  • Page 117 Configuration menus 7.6 Using your data logger in Bluetooth-only mode The Cobalt X data logger may be used in “Bluetooth-only” mode, that is, without any LoRaWAN functionality. In that case, the data logger behaves exactly as it does with LoRaWAN connectivity, but data transmission is handled via Bluetooth wireless “advertising frames”...

  • Page 119 Alarms and warnings When an alarm or warning occurs, the translucent outer ring on the Cobalt X casing flashes for as long as data logger remains in an alarm condition. The light stops flashing if, at the next programmed sensor read, the alarm condition has ended. Two colors are used for alarms: •...

  • Page 123 Alarms and warnings Acknowledging an alarm When an alarm is in progress, the Cobalt X data logger remains in an alarm state as long as the alarm conditions are present. If data logging was programmed with a delay to trigger an alarm only after a specified period of time, a stopwatch icon is displayed on the data logging screen (as described in the next section) and the alarm is activated when the limit is reached.

  • Page 125 Alarms and warnings Alarm delay indicator When setting up data logging, you may program a delay before the alarm is triggered. For example, you could set a 5-minute delay for the data logger to wait 5 minutes before triggering an alarm in case the temperature rises above, or drops below, the programmed limit.
  • Page 126 Maintaining your Cobalt X data logger Maintaining your Cobalt X data logger 9.1 Replacing batteries The Cobalt X data logger runs on batteries and/or AC power (via an adapter plugged into the USB port). Batteries are not installed prior to delivery. If data logging is currently running, we recommend that you not take any risks by removing both batteries at the same time.
  • Page 127 Maintaining your Cobalt X data logger 3. A single battery will ensure continued operation so you can replace the other battery without interrupting data logging: Remove one used battery from the data logger and replace it with a new one, making sure to respect battery polarity (see image printed inside battery slot).
