2. Sensor Filter Level: Signal digital filtering level on sensor measurements before reaching
the stage of determining the status. There are 16 levels of filtering, where level 15 is the
highest level and used when the sensor floats in a very non-stable liquid environment.
Level 0 doesn't filter at all, and is used for calm water conditions. It is advised to check
Water Calibration after changing this parameter.
3. Alarm Cycles Wait Before Transmit: Relevant for firmware versions before 4.1. This
determines how many Sample Intervals will be performed from the moment that a new
status change is first detected, until the new status is accepted as valid. If the status
changed during one of the cycles, the new status is ignored, and the process starts again.
The number of cycles can be between 1 and 7. 1 means that one additional cycle is added
to the original cycle, so two consecutive cycles must "agree" on the same status change. If
Immediate is selected, then the status is determined at the end of each cycle.
4. Over Range Delta: This is a value (in μA) above Water Calibration. If measured sensor's
signal is higher than Water Calibration + Over Range Delta + Hysteresis, the status will
be FAIL: SIGNAL TOO HIGH.
5. Under Range Set Point: This is an absolute value (in μA) that indicates an abnormal low
sensor signal value limit. If measured sensor's signal is lower than Under Range Set Point
minus Hysteresis, the status will be FAIL: SIGNAL TOO LOW.
6. Air Delta: A value (in μA) above Air Calibration. It is used for ensuring Air status even if
the sensor is a bit wet or doesn't sit correctly on the bottom flange. If measured sensor's
signal is less than Air Calibration + Air Delta – Hysteresis, then the status is AIR.
7. Sensor Current Pos Reading: This is a read only value (in μA), shown in red, of the
measured current through the positive wire of the sensor, representing current
consumption of the sensor. It is updated each time the Advanced screen is entered.
8. Sensor Current Neg Reading: This is a read only value (in μA), shown in red, of the
calculated current through the negative wire of the sensor, representing return current
consumption of the sensor. The value equals the difference between measured current
through the positive wire and Sensor Signal (shown on Main View Screen). It is updated
each time the Advanced screen is entered.
