17.2.3. To View <strong>and</strong> Change Input Filter Time<br />

An input filter provides damping of the input signal. This may be necessary to prevent the<br />

effects of excessively noise on the PV input.<br />

The filter may be turned off or set up to 10mins<br />

If the input is configured to accept process levels, eg 4-20mA, as in the above example, the<br />

parameter which follows ‘Eng Value Hi’ is ‘Filter Time’.<br />

For thermocouple <strong>and</strong> RTD inputs the first parameter to be displayed is the Input Filter Time,<br />

since the input scaling parameters do not appear for specific linearised inputs.<br />
