Speed of Response
The speed of response adjustment allows the user to collectively set a number of operating
parameters.
* = factory setting
• To change the speed of response, obtain the `SP' display.
• Scroll forward through the options (1-2-3) by pressing the "20" key. Scroll backward through the
options (3-2-1) by pressing the "4" key.
• When the desired option is displayed, stop pressing the key. The display will automatically return
to the Run mode (6 sec).
Fail-Safe
In the event a loss of echo or fault condition exceeds the `Waiting' period (see Speed of Response
above or Fail-safe Timer on page 11), the ` ? ' icon appears and one of the following fail-safe defaults
is immediately effected.
p = proportional span i = inversely proportional span * = factory default
• To change the fail-safe default obtain the `FLS' display.
• Scroll forward through the options (1-2-3) by pressing the "20" key. Scroll backward through the
options (3-2-1) by pressing the "4" key.
measurement response: is the limit to which The Probe will be able to keep up with rates of change.
If The Probe measurement cannot keep up with the rate of level change, set the
adjustment from `1' to `2'. If The Probe still cannot keep up with the rate of level
change, set the adjustment option to `3'. Avoid choosing an option that is too fast for
your application.
agitator discrimination: discriminates between agitator blades in motion, and the material (target) surface.
filter: discriminates between false echoes from acoustical and electrical noise and the
material (target) surface.
fail-safe timer: establishes the `Waiting' period from the time a loss of echo or operating fault
condition starts until the fail-safe default is effected. Adjusting the speed of
response will set the fail-safe timer to the default values in the chart. If a different
response is required, adjust the ‘FSt’ option (see page 11).
