The manufacturer cannot be held responsible for the product’s pollution with tracer gas.
► Ensure good ventilation in the area where the detector will be used.

NOTICE
Incorrect use of purge
A leak detection operation should be carried out on parts or equipment that contain any trace of substances that are aggressive, chemical, corrosive, inflammable, reactive, toxic, explosive, or on condensable vapors, even in small quantities.
► Do not use the purge to dilute these hazardous products. This is not its purpose.
The detector is equipped with an inlet vent optimizing the detector’s operation.
● If no inlet vent system is connected, the inlet vent is connected to the ambient air.
● The inlet vent status (opened or closed) depends on the parameters set by the user (see thechapter “Inlet vent”).

5.2.2

Connection of a neutral gas line (purge)
It is possible to connect the detector to a neutral gas line (purge) (at the customer’s expense).
The status of the neutral gas line (purge) (open or closed) is managed by the detector and cannot be
configured by the operator.
The use of a neutral gas (nitrogen, for example) allows for the leak detector background to be reduced.
The neutral gas should be different than the tracer gas used.
In addition to the purge, activating the ‘Pollution’ function is recommended (see chapter “Pollution function”).

WARNING
Risk of injury from contact with pressurized neutral gas
The product uses a pressurized inert gas (e.g. nitrogen) as the purge gas. Installations that do notcomply with or are not configured according to professional standards can endanger the user's life.
► Install a manual valve on the circuit at a distance of 3 m from the product, so that the neutral gas
supply can be locked out.
► Observe the recommended supply pressure.
► Always lock out and disconnect the neutral gas circuit before working on the product.
► Regularly check the condition of the pipework and supply circuit connections.

NOTICE
Incorrect use of purge
A leak detection operation should be carried out on parts or equipment that contain any trace of substances that are aggressive, chemical, corrosive, inflammable, reactive, toxic, explosive, or on condensable vapors, even in small quantities.
► Do not use the purge to dilute these hazardous products. This is not its purpose.
Flow
To guarantee best performance, the neutral gas supply must be dry and filtered, with the following characteristics:

21/98

Installation● relative excess pressure: 200 hPa● flow rate: 5 sccm (if pressure = 1 bar (absolute) at the inlet)
Use pressure
If the neutral gas pressure is too high, the inlet vent valve may remain closed.
● 0 to 0.3 bar relative (≈ 0 to 4.5 psig)● 1 to 1.3 bar absolute (≈ 14.5 to 19 psig)
Procedure► Connect the neutral gas pipework to the neutral gas purge connector (see chapter “Connection
interface”).

5.3

– In ‘Stand-by’ mode, the leak rate displayed corresponds to the detector’s background.
5. Carry out air inlet by pressing the [VENT] function key.
6. Prepare the part/installation to be tested (see chapter “Part/installation connection to be tested”).
– Spray method– Connect the part/installation to be tested to the leak detector inlet port.
– Evacuate the air from the part/installation to be tested.
– Bombing method– Place the part to be tested in a pressurization chamber with the tracer gas.
– Remove the part to be tested from the chamber and put it in the test chamber connectedto the leak detector inlet port.
7. Start the test by pressing the START/STOP button.
– Spray method– Spray the tracer gas on the points on the part that are likely to leak.
8. The various test steps are displayed.
When the detector has reached the most sensitive test mode, wait for the measurement to stabilize: the measurement displayed corresponds to the measured leak rate.
9. Stop the test by pressing the START/STOP button.
Sniffer test
1. Prepare the part/installation to be tested.
2. Select the ‘sniffer’ test method (see chapter “Test method”).
3. Set the reject point and warning set point if necessary (see chapter “Set points”).
4. Put the detector on ‘Stand-by’ mode.
5. Connect the sniffer probe (accessory).
6. Start the test by pressing the START/STOP button.

26/98

Operation
7. Then run the sniffer probe slowly over the areas of the part to be tested that may leak: the leakrate displayed varies when a leak is detected (quantitative value of the measured leak rate).
8. Stop the test by pressing the START/STOP button.

7.5

Calibration
Calibration is used to ensure that the leak detector is correctly adjusted to detect the tracer gas selected
and display the correct leak rate.
A calibrated leak is used to calibrate the leak detector.
By default, internal leak is selected to allow for a rapid calibration of the leak detector. It is also possible
to calibrate the leak detector using an external leak.
The leak detector should be calibrated with a calibrated leak of the same type as the tracer gas used.
Detector calibration
20 minutes after switching it on, the detector suggests that the user perform a calibration.
For correct use of the detector and to optimize the accuracy of the measurement, this calibration must be performed.
It is recommended to perform a calibration:● at least once a day,● for intense operation: start calibration at the beginning of each work session (e.g. workin shifts, every 8 hours),● if it is uncertain whether the detector is working properly.
Internal calibrated leak
The internal calibrated leak is specifically designed for the leak detector. It is composed of:●●●●a reservoir filled with 4He tracer gas (no internal calibration with other tracer gases),a temperature sensor (to take into account the effect of temperature on the leak rate),
an integrated diaphragm (to calibrate the leak rate),
an identification label (identical to the identification label of an external calibrated leak).

The calibrated leak is supplied with a calibration certificate.
Use a calibrated leak in the range of ≈ 10-7 mbar · l/s (≈ 10-8 Pa · m3/s).

In the case of intensive use of the detector, a spare internal calibrated leak is recommended. By default, the detector can be calibrated with an external calibrated leak.
External calibrated leak
The operator must use a calibrated leak containing the tracer gas selected (4He, Mass 3 or H2).
There are several types of external calibrated leaks, with or without reservoir, with or without valve, covering several ranges of leaks.
The manufacturer does not provide calibrated leaks in Mass 3 and H2.
The choice of external calibrated leak depends on application requirements: use a calibrated leak from the same leak rate range as the leak to be measured.

Graph screen: recording
Recording is used to store the measurements taken during the test in the control panel memory. It will
not save these measurements.
For each measurement, the leak rate and inlet pressure are recorded.
During recording, all of the leak detector functions are available.
After the detector is turned off (by a power failure or user manual shutdown), the current recording iscleared.
A record may include several measurements. The successive measurements are recorded one after theother in the recording: a visual cue (Δ) indicates the measure change.
To start a new recording, you must first save the current one.
When the memory is full and a recording is in progress, recording is automatically stopped.
1. Update the recording settings if necessary (see chapter "Graph screen: graph parameters").
2. Press [COMMENT] to add a comment (see chapter "Graph screen").
● Optional: this comment can be added at any time during the recording or during a pause● Comments can be viewed later in the backup .CSV file.
3. Press [START REC] to start recording.
● [START REC] is replaced by: [STOP REC], [STBY REC] and [COMMENT].
● Total recording duration: a flashing round dot is displayed, indicating that a recording is inprogress.
● None of the measurements displayed on the plot before the recording starts will be recorded.
4. If necessary, press [STBY REC] to pause.
● The pictogram glows red without flashing.
Total recording duration: the red dot is steady, indicating that the recording is paused.

Graph screen: graph history
The Graph history automatically records a history of the leak rate and inlet pressure values once theleak detector is on. It is not the user who triggers recording of the history. They do not save these values.
The history recording continues even when the user has started a recording (see chapter "Graph
screen: recording").
The history is recorded in the leak detector’s buffer memory.
The maximum duration of the history recording depends on the current setting:● 12 s display time: 60 min history recording● 1 h display time: 298 h history recording (≈ 12.4 days)► Double press on the graph screen to view the Graph history.

Pollution

To be enabledThis is a safety device for the detector. It prevents too much leaked tracer gas from penetrating the detector. We recommend setting the pollution set point to a maximum of 4 decades above the reject set point. If the leak rate rapidly increases above the pollution set
point, the cycle stops automatically and the leak detector returns to ‘Stand-by’ mode.
The function is only available with the ‘hard vacuum’ test method.
Useful function if the part or installation to be tested is likely to have gross leaks.

Correction factor calculation
When the leak detector is connected to an installation equipped with its own pumping system, only partof the leak will be measured by the leak detector. Calibration gives a direct reading of the leak rate bytaking into account the loss of tracer gas of the leak pumped by the pumping unit.
Calibration is performed via the Correction function.
Correction must be performed when the leak detector is already calibrated with its internal calibrated
leak.
When an external calibrated leak is used, it is recommended to take into account the calibration date
and temperature effect for calculating the target value from the calibrated leak value featured on its
identification label.
Corrected leak rate = target value = measured leak value x correction factor

Using this function is recommended when the background of the tracer gas is stable. Thisfunction is used to measure a leak rate that is lower:● than 2 decades in hard vacuum test mode: 1 · 10-12 mbar · l/s (1 · 10-13 Pa · m3/s) minimum● than 2 decades in sniffer mode: 5 · 10-9 mbar · l/s (5 · 10-10 Pa · m3/s) minimum
than the detector’s background, when the detector is no longer in roughing.

8.2.8

Regeneration
This function is used to ‘clean’ the tracer gas from the detector by automatically carrying out a series ofshort tests and inlet vents between each test. This is used to decrease the background following pollution with tracer gas.

NOTICE
Risk of pollution► Before starting this function, make sure that the leak detector is in an environment free of tracer
gas pollution.
For quick access from the main screen, configure a function key to [REGEN] (see chapter“Function keys”).

It is recommended to use this function when the background noise of the detector is high

1. Check that the detector is in ‘Stand-by’ mode.
2. Check that the inlet vent is “automatic.”
3. From the Settings screen, press [Test] [Regeneration].
4. Install a blank-off flange on the detector’s inlet port.
5. Press [Start].
– Regeneration stops automatically after 1 hour.
6. To stop regeneration before the automatic stop time, press [Stop] or the START/STOP key.
– Start a test (‘Zero activation’ function not enabled) to check that the detector is no longer polluted.

After regeneration, the inlet vent configuration is the same as it was before regeneration.

8.2.9

Massive Mode
This mode allows the detector to perform a test (4He only) on a very large leak when the detector has
not shifted to Gross Leak Mode and remains in roughing.
Massive mode can only be used if an external gauge is selected (see chapter “External gauge”):

Prerequisites for the detector to shift automatically into Massive mode:● function enabled● pressure < 100 hPa● pressure stabilized for at least 30 s
A message informs the use that the detector has shifted automatically into Massivemode.
The detector can then perform a qualitative test of a leak (information leak > 50 mbar

8.2.10Calibration check
Calibration check allows the user to save time because this operation is faster than full calibration.
The calibration check is performed with the leak detector’s internal calibrated leak (leak type parameter= ’internal’).
Calibration check is enabled if the calibration is set to ‘Check at start’ (see chapter “Calibration function”).
The leak detector compares the measured leak rate of the internal calibrated leak with the set leak rateof the internal calibrated leak:● If the ratio is within the limits allowed, the leak detector is properly calibrated.
● If the ratio is out of limits, a message appears suggesting that a full calibration of the leak detector
be started.

Cable characteristics
NOTICE
Risk of electromagnetic disturbance
Voltages and currents can induce a multitude of electromagnetic fields and interference signals. Installations that do not comply with the EMC regulations can interfere with other equipment and theenvironment in general.
► Use shielded cables and connections for the interfaces in interference-prone environments.

NOTICE
Safety Extra-Low Voltage circuits
The remote control circuits are equipped with dry contact outputs (30 V - 1 A max). Overvoltages andovercurrents can result in internal electrical damage. Users must observe the following wiring conditions:► Connect these outputs in accordance with the rules and protection of Safety Extra-Low Voltage(SELV) circuits.
► The voltage applied to these contacts should be less than 30 V and the current less than 1 A.
► 15-pin D-sub male connector for IP 20.

12.2.5

FormulasMantissa (1/10 V)
The “Mantissa” output corresponds with the leak rate mantissa.
FormulaU = Voltage measured (V) on analog output
Mantissa = U

Examples● U = 3.5 V -> Mantissa = 3.5● U = 6.9 V -> Mantissa = 6.9

Exponent (0/10 V)
The “Exponent” output coresponds with the leak rate exponent.
● The Exponent increases by 1 V per decade.
● The starting decade corresponds withe 10 V.
FormulaU = Voltage measured (V) on analog output
D0 = Low decade for 0 V
Exponent = 10 - U + D0

ExamplesExample 1
Low decade at 10-12 (10 V = -12) -> D0 = -12● U = 7 V -> Exposant = 10 - 7 - 12 -> Exposant = -9
● U = 2 V -> Exposant = 10 - 2 - 12 -> Exposant = -4
Example 2
Low decade at 10-10 (10 V = -10) -> D0 = -10● U = 7 V -> Exponent = 10 - 7 - 10 -> Exponent = -7
● U = 2 V -> Exponent = 10 - 2 - 10 -> Exponent = -2

Logarithmic (0/10 V)
The “Logarithmic” output corresponds with the leak rate value.
● The leak rate increases by 1 V per decade.
● The starting decade corresponds with 0 V.
FormulaU = Voltage measured (V) on analog output
D0 = Low decade for 0 V
Mantissa = 10(U - Valeur entière (U)Exponent = Integer value (U) + D0
Leak rate = Mantissa x 10Exposant

Logarithmic (0/10 V)
ExamplesExample 1
Low decade at 10-12 (0 V = 1 · 10-12) -> D0 = -12● V = 3.91 V -> Leak rate = 10(3,91 - 3) x 10(3 - 12) = 8.13 · 10-9
● V = 8.25 V -> Leak rate = 10(8,25 - 8) x 10(8 - 12) = 1.78 · 10-4
Example 2
Low decade at 10-10 (0 V = 1 · 10-10) -> D0 = -10● V = 3.91 V -> Leak rate = 10(3,91 - 3) x 10(3 - 10) = 8.13 · 10-7
● V = 8.25 V -> Leak rate = 10(8,25 - 8) x 10(8 - 10) = 1.78 · 10-2
