If you have an active audit running and you would like to update you're loggers, be advised that you should always finish the Audit.

In other words, make sure that the measured data from the loggers are pushed to the BaseStation/Cloud.

Before updating the loggers, check whether the data from the Audit was sent correctly to the Cloud. (Sync the audit and look at the data in the Graph Wizard)

If the loggers are updated and afterwards you would see that the data wasn't sent to the Cloud correctly, there is no way of retrieving the data and you would risk to lose the whole audit.

1. ‘Download logger update’ = Download the most current logger software to the BS from the Internet
   
2. 'Update logger’ = Transferring the downloaded software from the BS to logger(s) via Bluetooth
   

First of all, connect your base station to the Internet. Power up the base station. 

On your base station display, go to Settings, click Enter, go to ‘download logger update’, then click Enter.

The base station will tell you what logger software version you currently have and what logger software version is available on our server.

For example, the picture below shows the base station has logger software version of 3.0 and the available version on the server is 4.0.

Click Enter to download the newest software to the BS.

Go to ‘update logger’. Click Enter.

Click on the Bluetooth button of the logger(s) (left button on the logger(s)).

A window appears on your BS asking if you want to update the logger. Click Enter to update.

For example, the picture below shows a kW logger with serial number 190. It currently has software 3.0. Available logger software in the BS is 3.5. Click Enter to update the kW logger to software version of 3.5.

You will see the blue LED blinking fast. After the logger is updated, the blue LED will stop blinking.
