value can be changed to between 10 - 99 seconds using the keypad numeric entry
method. If a value outside this range is selected then it will not be accepted and “
ER LOW ER LOW ER LOW ER LOW ”
or “ ER HIGH
ER HIGH ER HIGH
ER HIGH ” will be displayed followed by return to the time entry screen again.
To confirm the desired value, press [Setup] or to escape without changing the value,
press [Mode].
10.4.4 Density Determination
It is possible to determine the density of solids or liquids using this mode. The user selects
the type of density to be determined and then enters values to be used by the balance.
The density mode allows the user to use a special Density Kit or use the below pan
weighing facility to perform the necessary weighing.
10.4.4.1 Density of Solids
To perform the density of solids test, the user must have a method to immerse the sample
in the chosen liquid. The density of the liquid must be known or determined from a look-up
table.
Steps:
Press [Mode] and then [Up] and [Down] keys until “
Density Solid
” or “
Density Liquid
” symbol is
displayed and then press [Setup] to enter chosen density mode.
When “
Density Solid
” is selected, the type of liquid used for the test must be selected:
Press [Up] or [Down] to select the liquid – water (display “
wAtEr wAtEr wAtEr wAtEr ”), ethanol (“ EtHAnOL EtHAnOL EtHAnOL EtHAnOL ”), or
other (“ OtHEr
OtHEr OtHEr
OtHEr ”).
For Water and Ethanol:
The density will be calculated based on the liquid temperature. A prompt “ WATER T WATER T WATER T WATER T ”
or “ ETH TEM
ETH TEM ETH TEM
ETH TEM ”, shortly followed by a numeric value e.g. “ 20
.
0 ” and the “
°C
” symbol at
the top left of the display will appear. Measure and enter the temperature of the fluid
using the keypad numeric entry method (see section 8.1Error! Reference source
not found.).
or
For Other:
The liquid density value must be accurately known, and entered manually. A value
will appear on screen e.g. “
0 00 0
.
500 500 500 500
g/cc
”. Enter the known density (g/cc) using the
numeric entry method (see section Error! Reference source not found.). Value
must be in the range 0.5
≤
2.0. If a value outside this range is selected then it will
not be accepted and “ ER LOW
ER LOW ER LOW
ER LOW ” or “ ER HIGH
ER HIGH ER HIGH
ER HIGH ” will be displayed followed by return to
the time entry screen again.
To confirm the desired value, press [Setup] or to escape without changing the
value, press [Mode]. The display will show “XX.XXX
g/cc
”. Press [Setup] to continue.
