3.3.4.2

Filter Type

There are three settings for the filter type

Filter Type = Off.

The display will respond immediately to any change in the PV input. If, however, there is

any input noise this will result in fluctuations of the reading

Filter Type = Integrating action.

This is designed for all process input types with the exception of weigh cell

transducers as explained in section 3.6. The function is exponential which means that, for a step change in

the input, the displayed value will move rapidly at first towards the new reading then gradually slow as the

reading approaches the PV value. The effect is that small rapidly changing input values are ignored. The rate
of response is set, in seconds, by the parameter

Int.t

, which only appears for this type of filter. The larger

the value the more sluggish the response

Filter Type = Step Band

. This is specifically designed for weighing applications. The filter only responds

when the displayed value becomes close to the measured value. This means that for a step change in the

input the displayed value will change rapidly towards the measured value then slow as it reaches this value.
The step band is set by the parameter

StP.b

which only appears for this type of filter. The units approximate

to 1

V steps – the larger the setting more sluggish the response over the final stages of the reading. This type

of filter is used, for example, where a weigh bridge or load cell is subject to vibrations

3.3.5

User Calibration Lists

These lists only appear if the ‘Type of Calibration’,

tYPE

, is configured for strain gauge type transducer

applications (see Configuration Chapter for further details). The lists below are shown for each type of calibration.
If

Type

OFF

the lists are not displayed.

Some parameter mnemonics remain the same for each type of transducer, but their functions may vary in detail

between the different types. The tables are repeated, therefore, for each calibration type.

The tables are followed by a description of procedure to use for each type of calibration.
