The detector offers 4 user interface levels for this section to
accomodate any application requirements.
START-UP USER INTERFACE LEVEL
After unpacking the unit, please fill
up the roughing pump with oil, as
indicated in the User’s Manual
E 750
1 Connect the main cable from the detector to the
proper power outlet.
2Depress 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
11
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
22
This level allows the operator to visualize some parameters without the possibility of making any
changes.
Same as Level
11
, this level is usually selected for production types of applications.
Access to all the control keys.
LEVEL
33
Same as level
22
but with possibility to set some parameters. This level is generally selected for
maintenance applications.
LEVEL
44
This level allows access to all the parameters and is generally used for settings all the parameters.
Note: When switching from level
44
to any other level, the switch can be performed without using the
password. This level is generally selected for R&D applications.

the unit goes in gross leak test mode, or when the pressure
has reached 5.10-1 mbar (0.37 torr), the unit goes in fine

He SIGNAL ANALOG SCALE DISPLAY AUDIO ALARM
Leak detector in hard vacuum or sniffing
test mode and zero function not activated.
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 x 10-7 mbar.l/s
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.

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.
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:
Operator could find an example in the User’s Manual C 540 8

AIR INLET VENT
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).

CALIBRATION
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.
