At the Bridge load line, the bridge load seen from the input of the amplifier must be
entered. This value is used, together with the input impedance from the amplifier (about
50KΩ), to optimize the measurement value. When a bridge with a large impedance is used,
this value becomes more important, because the voltage division at the input will cause an
error in the measurement.
At the Bridge compl. line, the internal bridge complementation can be selected. A selection
can be made from the following options:
1/1 bridge: with this selection a full bridge must be connected
½ bridge: with this selection the internal ½ bridge is connected toe the –IN pin.
The external ½ bridge must be connected to the +IN pin
¼ 120Ω with this selection a 120 Ω resistor is internally connected between the
¼ pin and the +EX pin. Just connect 1 120Ω staingauge between the –
EX and the ¼ pin, to measure this strain gauge.
¼ 350 Ω with this selection a 350 Ω resistor is internally connected between the
¼ pin and the +EX pin. Just connect 1 350Ω staingauge between the –
EX and the ¼ pin, to measure this strain gauge.
With the presentation setting, the presentation of the value on the display is influenced.
When it is set to default, the presentation will follow the setting in System menu 5. When it
is set to another value, this setting will overrule the setting in the system menu 5.
