13.2 LIQUIDS DENSITY – QUICK ACCESS KEYS
Each working mode features automatically displayed set of default keys. The set can be modified
by assigning out-of-list quick access keys to on-screen keys. Such operation requires particular
permissions level.
Default Quick Access Keys: parameters, adjustment, print header, print footer, product, user, start,
databases.
13.3 LIQUIDS DENSITY DETERMINATION
Glass-made sinker is a basic component for liquid density determination. Its volume, given on a
sinker hanger, is precisely calculated. Prior to determination, enter the sinker volume value into
balance memory.
Determination of density for a particular solid consists in weighing the sinker in the air first, and in
the liquid next. Upon completed procedure the result is displayed automatically.
Procedure-
1. Install density determination kit (Instructions found in Section 26.1)
2. Enter <LIQUIDS DENSITY> function.
3. Prepare sample that is to be measured (pour tested liquid to the beaker).
4. Start the process by pressing < Start> key.
5. Enter the sinker volume (the program displays volume of the most recently used sinker).
6. The following message is displayed in a bottom bar:
7. Hang the sinker on a stand (sinker weight measurement carried out in the air), confirm the
indication upon stabilization.
8. The following message is displayed in a bottom bar:
9. Now take the sinker out of the stand and put a beaker on the beaker basis (the beaker
cannot be in contact with the stand), gently hang the sinker on the stand making sure that it
is completely immersed in the liquid (measurement carried out in the liquid), confirm the
indication upon stabilization.
