DETECT CONFIG MENU
ADJUSTING THESE PARAMETERS WITHOUT FIRST
CONSULTING ONLINE ELECTRONICS LTD MAY CAUSE
THE UNIT TO MISS PIG PASSAGES OR GIVE FALSE
DETECTIONS.
The DETECT CONFIG MENU allows the user to configure the
detection parameters for the unit. This menu consists of
three pages as shown.
HIGH THRESHOLD – The Difference Level (DL) must
exceed this threshold before the unit will consider a possible
pig approach. (0 – 65535)
LOW THRESHOLD – The Difference Level (DL) must fall
below this threshold after being above High Threshold (HT)
to trigger a pig detection. (0 – 65535)
DELTA TIME – The length of time the Difference Level (DL)
must be above the Low Threshold (LT) after exceeding the
High Threshold (HT) before the unit will indicate a detection.
If the time does not exceed this value, then the pig approach
will be cancelled. (1 – 100 seconds)
AV VALUE TIME – The time period the Power In-Band (PIB)
is averaged over to calculate the Average Value (AV).
(1 – 100 seconds)
AV NOISE TIME – The time period the Power In-Band (PIB)
is averaged over to calculate the Average Noise (AN).
(1 – 100 minutes)
AV NOISE OVER – The value of Average Noise (AN) can be over ridden by the user, if this value
is set to zero then the calculated Average Noise (AN) will be used. (0 – 65535)
NUM AVERAGES – The number of samples that will be averaged to calculate the Power In-Band
(PIB). Increasing this value will smooth the resultant PIB output waveform at the expense of
increased processing time to compute the FFTs. (1 – 50)
UPPER FREQ BIN – The highest frequency bin to be included in the Power In-Band (PIB).
200Hz/bin (1 – 100)
LOWER FREQ BIN – The lowest frequency bin to be included in the Power In-Band (PIB).
200Hz/bin (1 – 100)
HARDWARE GAIN – The hardware gain configuration. (1 – 4)
SENSOR GAIN – The sensor gain level. (1 – 12000)
HP FILTER – Enables or disables the hardware high pass filter stage.
RESET TO DEFAULTS – Selecting this item will reset all detection parameters to their default
values. This option requires the user to confirm before it is actioned.
