Table 7: Configuration Parameters
7.4 Transient Sensitivity Adjustment
When initially manufactured, the devices are configured with an S3 Sensitivity of 130. This setting is
deliberately conservative to avoid the situation where the devices continually detect transient events on active
pipes.
Once PIPEMINDER-S has been installed for a few days the background S3 score may be evaluated using the
“S3 Value” plot in the graph on RADAR. In most cases a clear background S3 value can be identified with
occasional event spikes; the S3 sensitivity should be set midway between these two.
The resulting number of transient events identified per day can vary significantly between pipelines but the
situation where transients are continuously detected should be avoided.
When relocating a device, it is important to re-set the S3 Sensitivity back to 130 until the background
knowledge at the new location is developed.
