Zero function
 Deactivation of zero function:
The digital display shows the standard He signal.
Use Helium signal analog scale.
 Analog display:
 When zero function is activated, use the Helium signal zero scale.
 The He signal zero scale displays 2 leds signal centered around the zero value.
Example:
2 leds ash

 Purpose: the zero function offers the operator the possibility to detect small leaks that are
smaller than the helium background.
 Activation of zero function: connect the part or installation to be tested.
Operator could find an example in the Operating manual
