The operation range of each input must be configured (in Hz) through Lim Low
and Lim High parameters in SCALE option. Lim Low is configured with the minimum
input frequency (in Hz, without decimal point) and Lim High is (generally) the maximum
frequency of the range.
The indication on the display is configured by defining 2 points: P1 (Lim Low and
Eng Low) and P2 (Lim High and Eng High). The value configured for Eng Low will be
indicated on the display when the frequency input signal corresponds to the minimum
frequency of the operation range configured (Lim Low). In the same way, Eng High will
be generally the indication of the maximum frequency of the range (Lim High).
Observe the boundaries of the parameters Eng High and Eng Low and also the
resolution of the instrument when defining the decimal point position. The line defined by
P1 and P2 is not confined in the interval P1-P2, see Figure 11.
DC.PT places the decimal point on the display for readout in Engineering Unit
(EU) of each channel.
OFSET (as shown on the display) - allows the user to enter an off-set value in
Engineering Units to be added to the measured variable.
FILTER - this parameter provides the time constant of a first order digital filter
associated to the selected input. In order to leave the signal without filter set this
parameter to zero.
