The detector offers 4 user interface
levels for this section to accomodate any
application requirements.
1 Connect the main cable from the detector
to the proper power outlet.
2 Depress the main switch to position “I”. On
the control panel, the indicator lights flash.
3 The following screens are shown on the
LCD.
4 When the detection
pump reaches its
nominal speed, the
unit autocalibrates
itself.
5 When calibration is
completed, the unit is
ready to start a cycle.

LEVEL
This level has very limited information on the alphanumeric display (LCD). This level is
generally selected for production types of applications.
No access to control keys (Cycle
key included).
LEVEL
This level allows the operator to visualize some parameters without the possibility of
making any changes.
Same as Level
1
, this level is usually selected for production types of applications.
Access to all the control keys.
LEVEL
Same as level
2
but with possibility to set some parameters. This level is generally
selected for maintenance applications.
LEVEL
This level allows access to all the parameters and is generally used for settings all
the parameters.
Note: When switching from levelL
4
to any other level, the switch can be performed
without using the password. This level is generally selected for R&D applications.

The audio alarm offers 2 modes of operation. They are both linked to the zero function.
zero function not activated: the audio alarm starts when the He signal exceeds a fixed
set point: this set point is programmable.
zero function activated: the audio alarm is modulated with respect to the position of
the helium background.

How to read the He signal analog scale?
reject point is visualized by a blinking led.
if the leak value exceeds the reject point, the leds
will turned red (the blinking led will turn orange).
if the leak value remains under the reject point, the leds will remain green.
Example : Reject point = 1 .10-7 mbar l/s

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
1 .10-7 1 .10-8 1.1 .10-7 9 .10-8 2 .10-7
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 C 540

Purpose: the air inlet valve vents the inlet of the detector back to atmosphere at the end
of the test.
The indicator “inlet valve = off” indicates that the venting valve is not activated
(= closed) at the end of cycle.
The setting by default is «off» (= valve closed).

Internal: The internal autocalibration is automatically activated
during the start-up process. It doesn’t require any
operator action. Thanks to the initial autocalibration,
the leak detector can be immediately operational.
Internal autocalibration on request: it can be started by the
operator whenever needed (the unit has to be off-cycle).
The result of the autocalibration process is displayed.
External: The external autocalibration allows direct readout in cases of operation with
an auxiliary pumping system.
