Liquids/Density Determination (Mode Key - F7)
The Density of Liquids may be calculated using the sinker method. The volume of the sinker is listed on the
sinker hanger and must be programmed into the balance prior to calculating the density of liquids.
Press Mode Key and scroll to the F6 Mode, Press Enter Key PRODUCT will appear on the display. Press F2
Key and 0.00000 (flashing) along with SINKER will appear of the display. Press Up/Down Arrow Keys to
insert the precise sinker volume into memory, Temperature and Density. Press Enter Key to save and exit to
the Density (Solids) Calculation Mode.
Once you have completed the programming for the Density Mode (Solids or-* Liquids) simply weigh the
sample IN AIR (Press the Enter Key after stable weight reading) and IN LIQUID AIR (Press the Enter Key after
stable weight reading) the balance calculates the density of the sample that appears on the display as
RESULT.
When using Density Mode simply Press the Escape Key to begin another mixture. To Print a Report, Press the
Enter Key.
Animal Weigh/Dynamic Weigh (Mode Key - F8)
The Animal Weigh/Dynamic Weigh Mode may be used to determine the weight of live animals or when
working in less-than-ideal environmental conditions. In the Animal Weigh Mode the balance calculates the
average weight value over a number of readings taken over a time period. The mean average is designated
as stable readout on the weight display.
Press Mode Key and scroll to the F8 Mode, Press Enter Key, the ANIMAL WEIGH ICON will appear on the
display. Place Sample Container on the weigh pan and Press Tare Key. Place sample in container and Press
F2 Key, DETERMINATION appear on the display. When the Animal Weigh program is complete, RESULT
and the mean average will appear on the display.
Animal Weigh Mode may be adjusted to an AUTOSTART model – no need to press the F2 Key. This feature
automatically starts the weighing (DETERMINATION) process once an active sample is placed into the
container on the weigh pan. Press the Setup Key and Scroll to P2.9.7. Press Enter Key and use Up/Down
Arrow Key to select YES or No.
When using the Animal Weigh/Dynamic Weigh Mode simply Press the Escape Key to begin another test.
