Measurement Settings
→ Carrier gas flow
This item is only available in Carrier Gas mode.
Enter the total gas flow in Carrier Gas mode here. T-Guard™ Leak Detection Sensor
itself uses a probe gas flow of 180 sccm in Fine mode and 90 sccm in Gross mode.
Possible values: 60 sccm to 1000000 sccm.
Default setting: 1000 sccm

Flow test
This item is only available in Carrier Gas mode.
The T-Guard™ Leak Detection Sensor can measure the total flow in Carrier Gas
mode if the proof leak rate is applied during setting.

Line length
Here, you can set the length of the measuring line between 50 and 250.
For lengths longer than 50 cm, a set-up time of up to one second is set before the
real measurement starts.
This ensures that, for the gross test, the measuring signal is already on the sensor.
The the default value is 50 cm.

Depending on the smallest trigger value and the total gas flow/accumulation volume,
the T-Guard™ Leak Detection Sensor selects reasonable times for measurement.
Measurement times
→ Σετ Τιμεσ → Measuring time
Enter the total measuring time here. The cycle time of the T-Guard™ Leak detection
Sensor is longer than the total measurement time.
Possible values: 9 s to 300 s (accumulation), 3 s to 66.7 s (carrier gas). Default
setting: automatic measuring time.
Measurement settings
→ Set times → Waiting time Purge
This item is only available in Accumulation mode.
After every accumulation measurement, the chamber will be purged after a certain
time after the measurement. Enter this waiting time here.
Possible values: 0.1 s to 300 s.
Default setting: 4 s.
