•
Press the ↓ key to scroll to ‘Sensor Max / Min’ on Line 2 of the
display.
•
Press the ‘ENTER’ key and a series of values will be displayed.
The current sensor minimum and maximum measurements as well
as the peak sensor values since the last peak history reset will be
displayed. A ‘!’ at the start of a line indicates that the sensor is
currently overloaded. This may indicate the sensor is not working
properly or the pre-amplifier gain is too high and should be
reduced. Pressing the ‘ENTER’ key will refresh the display.
Pressing the ‘
→’ arrow key will display a prompt to erase the
sensor peak history. Press the ‘ →’ arrow again to erase the peak
values.
Sensors typically have peak values of -32768 and +32767. Values
within the range of about -/+2000 to -/+8000 are considered to be
“ideal” when the process is operating at normal conditions. Note:
In most cases the SONARtrac system will operate properly outside
of the “ideal” range of values.
Sensor minimum and maximum values should be within about +/-
30% of each other. If one or more sensors are outside of these
values, contact CiDRA Technical Support.
•
Press the ‘EXIT’ key to return to ‘Operational Mode’.
•
If the ‘Sensor Max / Min’ values are outside of their “ideal” range
adjust the gain per the procedures in Section 3.2.1.2.
