Parameter
Response Filtering
This parameter is used to turn filtered
output ON (01) or OFF (00).
The default setting is ON (01). The analog
output is filtered so that responses below
the 75 PPM are squelched. If the display
mode (P.-09) is set to ON (01) the display
shows 0 for any signal level below 75 PPM.
Some installations may wish to monitor the
small analog output changes that may be
created by the detector environment.
Turning filtering OFF (00) allows these
small variations around the minimum
analog output (for example, 4 mA, 1V.,
etc.) to be transmitted via the analog output
terminals.
NOTE: The detector display is OFF when
filtering is OFF (P.-09 is disabled).
NOTE: Whenever filtering is OFF the
detector display will turn ON for 10
minutes if the detector is re-zeroed (see
Section 4.3., Perform a Manual Zero).
This is intended to aid maintenance testing.
The analog outputs continue to transmit the
full, unfiltered range, and the alarm setpoint
remains active.
