Functional Description
If a sensor or strain gauge-bridge is connected with known unbalance, that unbalance-value
can be entered as ...-balance. That value is then electronically subtracted from the input
signal in the amplifier.
The use of the input balance can temporarily be disabled by setting use balance to no. The
value does not change and can be used again by setting use balance to yes again.
When a sensor or strain gauge-bridge with unknown unbalance is connected, it is possible
to use the auto-balance-function. If enter is pressed on the appropriate line, a
measurement is done and the result is placed on the ..-balance lines. The output of the
amplifier should be near 0 volt. In the larger ranges, an output signal of a few millivolts may
be left.
In the 100uV/V range however a maximum of 50mV may be left at the output because of
the 0.5uV/V resolution of the input balance.
The balance values are displayed and entered in the unit, displayed in this menu. The unit
value cannot be changed in this menu.
