6.3.3 Setting setpoints
You can set the leak rate for the setpoint to 1, 2, 3 and 4 separately.
When the setpoints are exceeded:
• If the setpoint 1 or 2 is exceeded, the measurement line in the measurement
window changes color.
• The setpoint relay of the digital output switches, see also "I/O module [}128]" or
the interface description.
Also setpoint 1 defines the trigger point for the different alarms, see also "Change
audio settings [}60]". It is also the limit for I•ZERO, see “Set and use the function
ZERO [}72]“.
