This feature lets you set Filter Limits for the selected Sensor/Transmitter.

Example 1:If, say, a Sensor/Transmitter is located in or near to an electrical switch panel, which can be very noisy electrically, occasional interference may occur on the radio link, which would be seen on the graph as a large spike in the data.
Sensor Filters are designed to remove such interference.
Example 2:If, say, a Sensor/Transmitter is monitoring temperature and the expected range for this application is -10°C to +50°C, a Filter could be set at say -40°C for the Minimum Value and +80°C for the Maximum Value and any readings seen above or below these values would be rejected.
Caution:Filters should only be used in exceptional circumstances.

6.To activate each channel's Filters, enter the required Minimum and Maximum values into the Min Value: and Max Value: dialog boxes.

Note:   For Temperature Channel Filters, the values should be whole numbers within the range 50 for the Maximum value and -40 for the Minimum value.

7.Click on Update. See Figure 965 above.

•This will save the Filter values for the selected Channel of the currently selected Sensor/Transmitter.

•The following message will be displayed in the Sensor's Filter window. See 966 below:

Filter Updated Successfully OLD

•For dual or triple Channel Sensor/Transmitters, repeat the above process for the other channels if required.

Caution: Setting Filters will cause data to be rejected above and below the Filter's limits.
Check that any Filter limits set are above and below the expected ranges.
