8.3.3 Selecting the auxiliary liquid
In this menu you can specify the auxiliary liquid you wish to work with. This setting is only relevant if you are determining the
density of solids! You can choose from the following auxiliary liquids:
Water: Distilled water is used as the auxiliary liquid. The density of
distilled water at various different temperatures is stored in the
balance (density table from 10°C to 30 °C) so it need not be
known.
Ethanol: Ethanol is used as the auxiliary liquid. The density of ethanol at
various different temperatures (from 10 °C to 30 °C) is also stored
in the balance so it need not be known.
Other: An auxiliary liquid of the user's choice, whose density at the
current temperature must be known.
Factory setting: Water is activated as auxiliary liquid.
8.3.4 Special function keys for density determination
Additional settings for density determination are available in the function key menu.
On the first page of the menu there are the following function keys for density
determination:
Start: You use this function key to start the density determination, so this
key must always be activated!
Density AL: You use this function key to enter the density of the auxiliary
liquid. This key is only needed if an auxiliary liquid other than
water or ethanol is being used.
Temp. (AL): You use this function key to enter the temperature of the auxiliary
liquid. You only need to use this key if you are using distilled water
or ethanol, because for other liquids the density at the current
temperature always has to be entered. For methods which do not
use an auxiliary liquid the key can be used to input the ambient
temperature so that it appears on the determination reports.
Vol. Sinker: You can use this function key to enter the volume of the sinker.
You only need to activate this key if you wish to determine the
density of a liquid using a sinker.
Vol. Pycno: You can use this function key to enter the volume of the
pycnometer. You only need to activate this key if you wish to
determine the density of liquids using a pycnometer.
Wgt. Pycno: You can use this key to enter the weight of the pycnometer. You
only need to activate this key if you wish to determine the density
of liquids using a pycnometer.
Result: You can use this function key to display the results of the density
determinations (statistics). Note: If there are no results in the
statistics, the key is shown gray and cannot be operated.
