CAL 2 - Linearity
Linearity is set in the balance’s software at the factory during the manufacturing process. It requires a
special set of weights that are not available commercially. When a CAL 1 function is performed the
linearity is automatically reset as well. Unless the balance is damaged the linearity will not change.
Therefore, CAL 2 should never be performed by the user.
Capacity Tracker
The capacity tracker located between the 0% and 100% at the bottom of the front panel display
provides a graphic display of the used and unused portions of the weighing range. Each segment
represents 10% of the balance’s total capacity. As 10% of the balance’s capacity is used the first
segment will illuminate. As 20% of the balance’s capacity is reached the second segment will light
and so on.
Selectable Vibration Filters and Stability Indicator
Balances are equipped with three user-selectable vibration filters, which reduce fluctuating readings
in varying weighing conditions. The balance was delivered to you set in the high filtering mode (Fil
HI). This is the most aggressive filtering mode. Normal filtering (Fil nor) and low filtering (Fil Lo) can
be selected for quieter conditions and faster response.
The stability indicator, OK, is illuminated when the variance of the readings are below the preset
stability parameters 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 sample 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.
To enter the filter selection mode, proceed as follows:
