Calibration
Calibration helps ensure that the leak detector is correctly adjusted to detect the tracer gas selected anddisplay the correct leak rate.
A calibrated leak is used to calibrate the leak detector.
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.

28/98

Operation
Tracer gas or test method setting modification
The selected test method and tracer gas have an impact on the calibration.
It is mandatory to perform a calibration of the detector if one of the following parameters is
modified:● test method (hard vacuum or sniffing)● tracer gas (4He, 3He or H2)
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, 3He 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 3He 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.

7.6.1

Calibration in hard vacuum test mode with internal calibrated leakInternal calibrated leak (see chapter “Calibration”).
Calibration can be performed when the detector is in test mode.
1. Allocate a function key to [Auto.Cal] (see chapter “Function keys”).

3. Press the [Auto.Cal] function key to start a calibration.

7.6.2

Calibration in hard vacuum test mode with external calibrated leak
External calibrated leak (see chapter “Calibration”).
Calibration with an external calibrated leak is advised when the reject point is far from theinternal calibrated leak value.
1. Allocate a function key to [Auto.Cal] (see chapter “Function keys”).
2. Configure the following settings:● test method: hard vacuum (see chapter “Test method”).
● type of calibrated leak: external (see chapter “Calibrated leak”).

7.6.3

Calibration in hard vacuum test mode with a pumping system in parallel
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 (‘Autocor’).
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
1. Allocate a function key to [Correction] (see chapter “Function keys”).
2. Select the ‘hard vacuum’ test method (see chapter “Test method”).
3. Press the START/STAND-BY button to start a test.
4. Press the [Correction] function key.
– if the value of the correction factor to be applied is known:– Press [Value] and configure the correction factor to be applied. The correction factor isthe coefficient to be applied to the measured leak rate.

Massive modeThis 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 “Leak Detection: Externalgauge”).

ActiveTo be selected
Prerequisites for the detector to shift automatically into Massive mode:● function activated● 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 · l/s (5 Pa · m3/s) only).
The maximum use time is 55 minutes.

Tracer gas or test method setting modification
The selected test method and tracer gas have an impact on the calibration.
It is mandatory to perform a calibration of the detector if one of the following parameters is
modified:● test method (hard vacuum or sniffing)● tracer gas (4He, 3He or H2)
For quick access from the main screen, configure a function key to [TRACER GAS] (seechapter “Function keys”).

Hydrogen test

WARNING
Risk of injury due to the use of hydrogen as tracer gas
Hydrogen can be used as a tracer gas for leak detection. Depending on its concentration, in the worst
scenario, there may be a risk of explosion.
► Never use a tracer gas with a hydrogen content greater than 5%.
► Use hydrogenated nitrogen as a tracer gas: mix of 95% N2 and 5% H2.
The detector’s background is higher in H2 than in 4He/3He.
Typical background in H2, in test, when the detector is equipped with a blank-off flange on the inlet port:● at start-up: low range ± 3 · 10-6 mbar · l/s (3 · 10-7 Pa · m3/s)● after 2 or 3 hours : low range ± 5 · 10-7 mbar · l/s (5 · 10-8 Pa · m3/s)

Leak Detection: Calibration
Calibration helps check that the leak detector is correctly adjusted to detect the tracer gas selected anddisplay the correct leak rate (see chapter “Calibration”).
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 with an external leak (see chapter “Calibration”).
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.

1) Initial setting: see chapter “Tree diagram of the Settings menu”‘Calibration checking’ details
For quick access from the main screen, configure a function key to [Calib. check] (seechapter “Function keys”).
At any time, the user can start a calibration check: with the leak detector in “Stand-by”
mode, press the [AUTOCAL] function key twice within 5 seconds.
Calibration checking allows the user to save time because this operation is faster than full calibration.
The calibration control is performed with the leak detector’s internal calibrated leak (leak type parameter= ’internal’).
Calibration checking is disabled if calibration is set to ‘manual.’
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.

Leak Detection: Internal Pirani gauge calibration
This function is used to calibrate the detector’s internal gauge.
Prerequisite(s)● Test method: hard vacuum● Most sensitive test mode selected● End of cycle: operator (manual end of cycle by the user)
Procedure
The calibration takes place in 2 stages: setting the limit pressure and setting the atmospheric pressure.
Access: Settings Screen + Menu [Advanced] [Leak Detection] [Internal Pirani Calibration]
1. Close the detector’s inlet with a blank-off flange.
2. Set the ultimate pressure.
– Start a test: press the START/STAND-BY button.
– The ‘Pressure’ value decreases: wait for this value to stabilize (about 5 minutes).
– Make sure that the internal pressure is significantly lower than 1 · 10-3 hPa.
– Press the [>HV] key.
3. Set the atmospheric pressure.
– Start a test: press the START/STAND-BY button.
– Create an inlet vent: press [Inlet vent].
– Ensure that the detector is at atmospheric pressure.
– The ‘Pressure’ value increases: wait for this value to stabilize (about 5 minutes).
– Press the [>Atm] key.

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

90/98Appendix
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
