The damping filter cuts off input values exceeding from the limits of a simmetrical band. This band becomes more selective as the
filter level is increased.
The filtering level is programmable from 0 to 9. Level 0 disables the filter.

The 9181 model of DIGIMASTER series done with new
technologies and giving high performances like: display
range of ±9999 points, up to 30 points of linearization,
direct access to the setpoint programming, 31
programmable logical functions and high conversion
rate @ 555 / second.
The 9181 is an instrument to measure and control with direct
indication in engineering units. The multifunction input board
allows to connect Load-Cells (mV) or Shunts to measure DC
currents, Process signals ±10V or ±20mA or lineal
potentiometer for measure distance, length etc.. The
instrument supply different excitation voltages for sensors,
24V @ 30mA, 2.2V @ 30mA, 5 or 10V @ 120mA allowing
supply up to 4 Load-Cells; This differents voltages are
selected by internal jumpers.
Thanks to its high conversion rate (555/s) can read peaks or
valley values from signal with a minimum width of 2,1 ms. An
analog output (ANA option) transmitting 200 readings per
second, an optocouplers output option (4OP o 4OPP) with a
reaction time of 2,1 ms or 2 relay or 4 relay as well as the
easy link to a PC through RS2 or RS4 serial output option
using protocolos burster, ISO1745 or MODBUS RTU with the
possibility of using a logical function that sends through RS
200 informations of variable per second. All is conferring to
the instrument very high performances.
In adition the instrument has three kind of filters that allow to
stabilize the reading with signals comming from differents
process.
A special function nr27 SAMPLE & HOLD allows to stop
during hold time the reached value during the measure as well
as the PEAK, VALLEY, PEAK-PEAK values and also the
comparison with SETPOINTS (selectable).
The basic instrument is made with main board, supply filter,
input board and display (see figure on page. 4).
The basic functions of the instrument are display of input
variables value, reading and store of peak,valley and peak-
peak of this variables as well as funtions Hold, Tare and reset
of them. The model 9181 also accept the following output
options:
