Sensitivity

The actual sensitivity level of the module under current conditions. The Shut-In module is
showing on the one hand the overall sensitivity of the module, on the other hand it shows the
sensitivity of each monitored pressure transmitter (which can show different sensitivity states).

The following information can be shown:

• Undefined:

transmitters are showing different sensitivity states.

Running Leak Rate/Running Pressure Drop

For the Signature-Test and Differential-Test of the E-RTTM module, as well as for the Mass
Balance module, it shows the average value of the estimated leak rate in volume or mass flow.
For the Shut-In conditions it shows the average value of the estimated pressure drops.

Pos. and neg. Leak Threshold under current conditions

For the Signature-Test and Differential-Test of the E-RTTM module, as well as for the Mass
Balance module, it shows the smallest detectable leak rate. For the Shut-In conditions it shows
the smallest detectable pressure drop.

INFORMATION!
