Quick Guide to Specific Gravity on an OHAUS Valor 3000 Xtreme
by Carl S. Joslyn
For processing applications where determining the density
of a mix is important, the OHAUS Valor 3000 Xtreme offers a quick
solution. The Valor 3000 Xtreme was developed with a Specific
Gravity mode which allows it to compare a sample weight on the
platform against a reference weight in memory, displaying the
results relative to the sample weight.
This mode is useful for applications like determining the amount
of aeration in a cake mix for a commercial bakery. By using the
same container with the exact same sample volume, an equal volume
of the mix can be compared to an equal volume of water. The result
can then be used to adjust the process for more or less
aeration.
- Turn on scale with nothing on platter and ensure it is reading
0.
- Press Mode/Unit/Menu key until the display shows Set.rEF the S
icon.
- Press the Yes key to establish a new reference weight in memory
(if you want to use the reference already in memory, press the No
key and go to step 7).
- The scale's display will blink until the reference weight is
stored in memory.
- Place the container on platform and press the O/T/On/Off key -
display should read 0 again
- Fill the container with water until the proper volume is
measured. Press the Enter/Cal key to store the weight in
memory. The display will show the weight of the water with
the S icon blinking.
- Replace the reference volume of water with the same volume of
sample material in the same container. Press Enter/Cal.
- The display will now show the specific gravity of the
sample.
- For ongoing process control where the same container and volume
will be used, the scale will retain the reference weight of the
water in memory.
