Response rate
The device's ability to respond to material level changes is designed to exceed even the
most demanding installation requirements.
The Response rate (2.3.4.) (Page 174) setting automatically presets various parameters
affecting the device response to material level changes as follows:

If any of these parameters are independently altered, a Response rate (2.3.4.) (Page 174)
parameter alteration automatically resets the independently altered value.
Slower Response rate (2.3.4.) (Page 174) provides greater measurement reliability.
Faster performance may be obtained by independently setting Fill rate/minute (2.3.2.)
(Page 173) and Empty rate/minute (2.3.3.) (Page 173). Maximum rates may be impeded by
Echo lock (2.11.5.4.) (Page 235),Scan delay (2.1.14.) (Page 167) and Shot delay (2.1.16.)
(Page 168) values.
A.12
Analog output
The mA output (current output) is proportional to material level in the range 4 to 20 mA. 0%
and 100% are percentages of the full-scale reading (m, cm, mm, ft, in). Typically, mA output
is set so that 4 mA equals 0% and 20 mA equals 100%.
