Performing a measurement 
1. Make sure that the device is in Ready mode - see "Modes" on page 15.
2. Select appropriate product - see "Selecting a product for measuring" on page 23.
3. Place a septum 
 on the product/package  to be measured/analysed. This ensures 
leak-free gas extraction and thus accurate measuring.
4. Penetrate the septum 
 with the needle  so that the gas can be sucked in from the 
package through the tip.
CAUTION! Do not let the needle tou17ch the product, fluid or anything else in 
the package, as this could soil the needle, hose or filter.
If this happens, the needle, hose and filter must be replaced to avoid destroying 
sensors or other items inside the unit.

.
6. If selected product requires keying in of data before measurement (see "Edit product" on 
page 33 for details) Data required. Press   will be displayed in the bottom of the 
measuring screen

7. Pressing the   key will bring up the appropriate touch screen keyboard for keying in of 
the required data. Key in the data and confirm by pressing the OK key, which will either 
bring up the next data request screen if required or return to the measurement screen
