Process course:
• Press < Local parameters> key to enter the setting of local
parameters in density mode.
• Press < Standard liquid> key to select the auxiliary liquid used
for the density determination procedure. If the auxiliary liquid is other
than “Water” or “Alcohol”, then select “Other” from the available list.
• Press <
Temperature>
i key and specify the temperature of the
auxiliary liquid [°C]. Accept inserted value by pressing key.
• If „Other” liquid has been selected, then press < Standard liquid
density>
insert the density value of the auxiliary liquid expressed in
[g/cm
3
]
for the specified temperature of the measurement.
• On specifying the parameters exit to main menu of the density
mode by pressing key.
• In order to start density determination of porous body, press <
Determine porous body density>
key, using a pre-defined hot keys
on terminal’s display.
Caution:
If in the local parameters, <
Ask about sample number> function
is enabled, then on initiating the process, the system asks for inserting
the number of tested sample. The inserted sample number is linked to
the process data and saved in the database.
• The first phase of the density determination of a porous body in the
air. Place the object on the scale’s weighing platform. On obtaining
stable measurement result, accept it by pressing
key,
• Then immerse the tested porous body in oil to fill its pores. Place
the tested porous body impregnated with oil on scale’s weighing
platform. On obtaining stable measurement result, carry out the
measuring process, and accept it by pressing
key,
• In the third step, weight the tested porous object impregnated with
oil in the auxiliary liquid. Place the tested object in the auxiliary liquid,
on scale’s weighing platform and immerse both in the auxiliaty liquid.
On obtaining stable measurement result, carry out the measuring
process, and accept it by pressing
key,
