Monitoring
→ Contamination limit
Set the contamination limit to "High" in order to be able to measure a high helium
content in the test gas. Set it to "Low" in order to protect the sensor from receiving
too much helium, which reduces the lifetime of the sensor. The default setting is
"Normal".
"Low" stops the measurement after 30 s at 40 ppm, "Normal" after 30 s at 75 ppm,
"High" after 30 s at 200 ppm, or in case of higher concentration after the relevant
shorter time (e.g. double concentration after the half time).
Monitoring
→ Pressure limits
Enter a permitted pressure range for the Wise Technology™ sensor here. Exceeding
the pressure limits will give a warning. Use this setting to be warned in case of
clogged filters or wrong test settings.
Possible values: Low limit: 10 mbar to 350 mbar, High limit: 250 mbar to 800 mbar.
Default settings: 180 mbar and 350 mbar. The high limit must be 100 mbar higher
than the low limit.
