Introducing Sentia™ General warnings and precautions When you use a new vial of strips, you may need to establish a WiFi connection to the Internet so that the latest test strip calibration data can be downloaded (see Page 8). You will need to download calibration data every 3 months or so to stay up to date with the test strips we produce. Always follow the safety procedures and precautions listed here and throughout this user guide.
Your Sentia™ kit Your Sentia™ kit contains the following items: 1. 2. Analyzer This User Guide 3. 4. Power Supply/ USB Cable Spare Cap Intended use of the Sentia™ system The Sentia™ system can be used to determine free sulfur dioxide (SO2) levels in wine post-fermentation. It is portable and fast, allowing free sulfur dioxide levels to be determined around 30 seconds after sample application.
The Sentia™ system analyzes a sample applied to a Sentia™ test * strip . The sample is applied after the test strip has been inserted into the Sentia™ analyzer's strip port. The sample mixes with dried reagents inside the strip and the analyzer detects the free sulfur dioxide levels. The result is then displayed on the analyzer screen in units of either parts per million or mg/L (user selectable). Up to one thousand records can be stored in the analyzer’s memory.
2. Getting started Powering the analyzer The Sentia™ analyzer is charged via a micro USB cable and AC power supply (included). It can also be charged using a micro USB cable connected to another suitable power source (such as a USB port on a computer). It is best to make sure that the analyzer is fully charged before first use. AC power supply and cable To charge analyzer, plug in AC power supply and connect the USB cable Your AC power supply comes with a range of plugs.

First time use Turning the analyzer on and off To turn the analyzer on, touch the power button briefly. You can turn the analyzer off by touching the power button several seconds and answering yes when prompted for confirmation. for If the power button or touch screen are not responding, you can force the analyzer to shut down by disconnecting the external power supply and holding your finger on the power button for around 15 seconds until the screen goes black.
Before you run any tests you should check the date and time (displayed at the top of the screen). The Analyzer uses the internet and your time zone to set the date and time. If the date and time are not correct, you will need to set the time zone. Set the time zone as follows: 1. From the Home screen, touch the SETTINGS button to navigate to the Settings screen, then select Analyzer and then Time zone 2. Select your region, touch , then select your sub-region.
Connecting to a wireless network If it has been more than three months since you ran a test and you are using a new vial of test strips, a wireless (WiFi) network connection with Internet access may be required for the analyzer to download the necessary calibration information for the strips. If not already connected, follow these steps to connect to a wireless network: 1. From the Home screen, touch the SETTINGS button, then touch Connectivity to navigate to the Connectivity screen 2.
Guidance on wine types Rosé For Rosé wines, winemaker discretion is advised when selecting the ‘Red’ or ‘White’ sample type (see Page 12). The best selection may depend on skin contact the wine received during processing. In most instances selecting ‘White’ will generate acceptable results but there may be some cases where the ‘Red’ option yields better results. Validation of results via an alternate method for your particular wine is highly recommended. 2.
3. Running a test Preparing to run a test Items necessary to conduct a test are as follows: 1. Sentia™ analyzer 2. A vial of Sentia™ free sulfur dioxide test strips 3.
