Functional Description
The parameter range of determines the interpretation of the range-parameter. As it is set
to amplifier the range represents the amplifier-range in V/V. When it is set to sensor, the
range takes into account the values from the sensor-menu and the range is shown with the
physical unit from the sensor-menu. If range of is set to strain, the range is calculated using
the values in the strain-menu and the physical unit will be m/m, g/mm2 or N/mm2. As the
range of parameter is changed, the unit parameter will change as well. That unit can not be
modified from within this menu but only in the sensor- and strain gauge-menu’s.
The range of parameter also determines how measurements are shown on the display,
when the presentation parameter in the system menu 5 (behind the set meas button) is set
to physic. unit.
The electrical range of the amplifier (when range of is set to amplifier) can be set between
100uV/V and 1 V/V. Using smaller bridge-voltages than 5 volt, this has limitations on the
smallest value that can be set as the range.
If the range is adjusted wrongly, an indication:
Calc. gain too large ! !
Settings adjusted ! !
appears in the lower part of the LCD-display. The settings are adjusted to the highest
possible gain.
The value for Output V determines the output-voltage when full-scale input signals are
applied. It is thereby possible to match to data-acquisition equipment, connected to the
amplifier-output.
Most modern systems accept the -10…+10 volt signals that PICAS delivers by default.
Note that the full-scale output voltage, as specified with Output V, is not the same
as the maximum output voltage. Even when 5 volt full-scale is chosen, a maximum of
14 volt may arise on the output during overload-conditions.
