However, the jug can be used to measure while being hand held - under a tap for
instance. As the contents increase the reading will be spoken or can be requested at
any time by pressing the
Speak button. The more the jug is tilted the less accurate its
readings will be - it may even say “Zero” if tipped far enough. If you wish to pour some
liquid from the jug it is important that you level it again before taking a reading - ignore
the announcements while the jug is tilted.
Ensure that the jug is firmly locked onto the base particularly before lifting or pouring.
The jug will turn itself off if no buttons have been pressed or any liquids added or
removed for 30 seconds. This is indicated by a short double beep sound. This is to
conserve battery power and does not mean you have to start again if you are in the
middle of measuring. Simply press the
Speak button to wake the unit up with all the
readings stored. If you do not realise it has turned off and you add more liquid then you
will find that the jug will not speak the new weight automatically. Again, just press the
Speak button and you will hear the correctly measured new weight.
Be careful not to touch the jug while measuring, as doing so will reduce the accuracy.
User defined liquid
If you have a requirement to measure a very unusual type of liquid, perhaps a sauce or
soup, then there is the facility for a user defined liquid.
To use this option hold the Liquid button down for five seconds until the jug says:
“Empty jug then press zero”. Empty the jug and press the Zero button until it says: “Fill
the jug to calibration mark and press Liquid button”. If you feel inside the rear of the jug
you will feel a raised rib projecting up from the bottom of the jug to almost half way to
the top. This is the calibration mark. Add your liquid until it is level with the top edge of
this rib (970 millilitres), then press the
Liquid button until the jug says: “User defined
liquid set up complete”.
You will now find that when you next use the Liquid button a User defined choice has
been added. This selection can be re-calibrated for a different liquid at any time by
repeating the above. If you want to remove the User defined liquid from the options
then, when asked to fill the jug to the calibration mark, just leave it empty and press the
Liquid button. The jug will understand that you no longer want to use this option and
will remove it until you re-calibrate it again with another liquid.
Please note that the base is not waterproof or microwave safe and should never
be placed in water or a microwave. It should be cleaned by wiping with a damp
cloth then dried. The jug itself is both dishwasher and microwave safe.
