6.4 Settings for the measurements
6.4.1 Setting setpoints
By setting a setpoint, you decide what quantity of gas lost should be tolerated with a test
object.
You can set two setpoints on the device. You can use setpoint 1 to, for example, find "very
good" test objects and setpoint 2 displays up to what value the test object is "still okay."
You can only use setpoint 2 when the function for the sniffer line key is set to “Setpoint” in
the settings,
