The run-up process takes longer than 3 minutes if the device was turned off for a long

time. Once the T-Guard™ is ready for the measurement, the current measured value

of the leakage rate is displayed on the screen. Otherwise the device is activated with

a warning after 30 minutes at the latest.

The name of the current parameter set is displayed in the top line of the Leak Rate

screen. If the parameter set is changed later, there will be an asterisk before the

name of the parameter set.

Notice If the T-Guard™ Leak Detection Sensor has been switched off for several

days, the initial sensor current may be too high to measure with the highest

sensitivity. In this case, apply external air to the reference inlet and wait for

two hours.

Then, the T-Guard™ Leak Detection Sensor will meet its specification.

Using external air, the unit will display "Background OK".
