13.8.5 Changing the error limits, the warning limits and the hysteresis
of the density factor
A monitored value can be:
• in the normal operating range
• in the warning range
• in the error range
You can set 4 limit values: 2 error limits and 2 warning limits.
→ To set the limit values, see chpt. 13.8.5 Changing the error limits, the warning limits and the hysteresis of
the density factor.
Figure 19 in 13.4.5 explains how the device reacts when the monitored value enters in another range (for
example, from the normal range into the warning range). The reaction time depends on the hysteresis value
and if the monitored value increases or decreases.
By default, the monitoring of the density factor and the diagnostics are all disabled.
To change the error limits, the warning limits and the hysteresis of the density factor, do the following:
→
Select the device in the navigation area.
→ SAW sensor
→

The new settings are displayed.
→
Finish
The limit values and the hysteresis value are changed.
