Selectable Filters:
All balances are equipped with three user-selectable vibration filters which reduce nervous readings in varying
weighing conditions. The balance was delivered to you set in the low filtering mode (Fil Lo). This is the least
aggressive filtering mode. Normal filtering (Fil nor) and high filtering (Fil HI) can be selected for noisier con-
ditions and faster response.
The stability indicator, OK, is illuminated when the variance of the readings are below the preset stability pa-
rameters as selected by the user. The stability indicator is useful in determining the stability of the weighing
environment. In normal weighing the OK stability indicator should come on within five seconds after the sam-
ple has been placed on the pan and the windscreen is closed. If the stability indicator does not come on or takes
a very long time this indicates it is too noisy of an environment for that level. Try improving the environment
or raise the filter level to enter the selection mode proceed as follows: To exit the selection mode and return to
normal operation, turn the balance off and then back on again at any time.
User Action Balance Response
1 Press ON/OFF and MODE/UNITS
simultaneously.
The current filter, Fil nor (filtering normal), Fil
Lo (filtering low), or Fil HI (filtering high) and
OK are displayed.
2 Press the SEND button until the desired vibra-
tion filter is displayed. Then press the RANGE/
FUNCTION button to save the setting.
Balance shows SAVED and returns to normal
weighing. The balance will remain in the cho-
sen filter setting even if turned off and back on
Density Determination:
Scientech does not offer a density determination kit nor do you need one to determine density. Density is mass
(grams) per unit volume (cubic centimeters).
In order to determine density of a solid, place a graduated flask with a known volume of water on the pan of
the balance, tare the balance, and then place the solid in the flask of water. Divide the displayed weight in
grams by the increased volume of water. The result is the mass per unit volume of the solid in g/cc.
To determine the density of a liquid, place an empty graduated flask on the balance weighing pan, tare the bal-
ance, then pour the liquid into the graduated flask. Divide the displayed weight in grams by the volume of the
liquid. The result is the mass per unit volume of the liquid in g/cc.
Below Balance Weighing: Please use care when installing Below Balance
Weighing. The suspension can be damaged if over tightened. The overload
protection which is built into the pan assembly is not available at the below
balance hanging device. Therefore, care must be taken to avoid side shocks
or pulling too hard on the hanging device. When using the below balance
weighing option it is suggested that you calibrate the scale from below.
For applications requiring suspension of weight below the balance, a 6-32 threaded screw is provided. To access
the set screw, proceed as shown. Then mount the balance on a solid pedestal or surface with a hole under the bal-
ance to allow access to the hanger. While using the below balance weighing feature all other functions of the bal-
ance operate normally. The balance is capable of weighing both above and below simultaneously provided the
capacity of the unit is not exceeded.
