rotronic AWEY 2AG4J-AWEY AwEasy Water Activity Devices

GENERAL DESCRIPTION

The AwEasy is a standalone measurement head for water activity and temperature. It can be operated as standalone device together with the free AwEasy App for Android and iOS.

For more information please visit www.processsensing.com or www.rotronic.com or scan the QR code (also on the measurement head), which gives you the direct access to the Rotronic Online Manual with further explanations.

MEASUREMENT ARRANGEMENT

Before charging the AwEasy put the correct socket adapter on the power adapter (PS1006). Then connect the USB-A to USB-C cable with the USB-A plug to the power adapter and with the USB-C plug to the wireless charging plate (AwEasy- Charger). To disconnect the device from the power supply, disconnect the power adapter from the socket.

NOTE: The power adapter must always be easily accessible.
WARNING : The power supply can only be used up to an ambient temperature of 45°C. See also the temperature limits for the battery and charging in the TECHNICAL DATA.

STARTING THE APP

Please go to the App Store (iOS) or the Play Store (Android) and download the AwEasy App. After the installation of the AwEasy App you can then start the application.

NOTE: Please make sure before using the device, that it’s fully charged. For turning on or off the AwEasy press and hold the touch button on the top (below the display) for at least 10 seconds. To add the AwEasy measurement head to your device list, go into Measurements and click on the top right the “+” to add a new AwEasy device. The App will automatically search for the AwEasy measurement head

As soon as the measurement head is connected it will be shown in the Probes overview with a green arrow on the left side. If there is no active connection with the measurement head, it will be shown as discon-nected (with no green arrow).

STARTING THE MEASUREMENT

To start a measurement, click on the specific connected measurement head and click on the bottom of the measurement overview the Add new measurement button.

After that the Measurement Settings menu will open. To start a new measurement, it needs to be filled out at least the Measurement Name and the Batch Number. Content and Notes are optional for the measurement. In the end the measurement method has to be chosen. Rotronic recommends for the AWQ measurement a dwell time of at least 4 minutes and a temperature stability of 0.1°C/min. For the standard AWE measurement Rotronic recommends an AW stability of 0.0001 aw/min and a temperature stability of 0.01°C: Optional it’s also possible to set an AW Setpoint. After setting the Measurement Settings it is then possible to start the measurement by clicking the Start button. As soon as the measurement starts a moving green line will appear and the Start button will change to Stop (to stop the current measurement).

NOTE: Do not use the AwEasy direct after charging. The charging generates heat in the battery, which can affect the measurement. Please wait at least 1 – 2 hours.

STANDALONE MODE

To use the standalone mode, it must be set up first over the AwEasy App. Go from the Main Menu into Settings. In the Settings menu the File Name and the Batch Number needs to be defined. In there you can select different types like Date, Serial Number etc. for the generated Batch Number or File Name. Most important here is that in the Batch Number the Increment Number is selected as type. Next go into Measurement and select the desired AwEasy in the probes overview. Set up the measurement as described in STARTING MEASUREMENT above and click on Save.

After that, the AwEasy measurement head can be used without a Smartphone. The measurement data from the AwEasy will be automatically loaded to Smartphone as soon as it is reconnected. To add a new measurement and to start or stop a measurement just double tap the touch button. The following icons will appear on the AwEasy display:

GENERAL GUIDELINES

To make accurate and reproducible measurement, follow the following general guidelines to measure water activity:

• Measure water activity only in rooms with constant temperature; Ideal are rooms with small daily and yearly temperature variations. Avoid heating of the measuring equipment by sun radiation or radiators, draught, body radiation etc.
• Put the samples into the disposable sample cup and put the lid on it. The probe and the sample must stay in the same room for acclimation (normally room temperature)
• Avoiding warming up the probe and sample through body heat. Do not hold too long in your hands.

SAMPLE CUP

Put the sample into the sample cup.
To avoid cross-contamination do not fill more then up to the fill line.

Put the probe immediately on the sample cup after having filled in the sample to avoid humidity exchange with the ambient. The measurement time may vary depends on the probe. humidity and temperature value are ready to read when the values are stable for at least 1 – 2 minutes.
