Autozero

Determination and compensation of the refrigerant background. With this function,
the internal ZERO level of the leak rate signal is determined in order to avoid a
readout of the internal refrigerant background and mistaking it as a properly
measured value. If subsequently negative leak rates are obtained due to this
correction, the stored offset values are changed so that ZERO will be the lowest
value which can be obtained. In this way the values adapt automatically to a
decaying background (adaptive background correction).

Internal background

The existing partial pressure in the measurement system. The level of the internal
background is measured all the time and subtracted from the measured signal.

2.1 Description of the Functions

The Ecotec E3000 is capable of detecting and quantifying the refrigerant sucked in
through the sniffer line by means of a selective mass spectrometer.

The Ecotec E3000 is composed of the following principal subassemblies:

• a quadrupole mass spectrometer as the detection system

• a high vacuum pump system

• an inlet system for the gas flow

• the corresponding electrical and electronic subassemblies for supplying power
and for signal conditioning.

kina22e chapter 2.fm technical handbook(1206)

Fig. 2-1 Vacuum Diagram of the Ecotec E3000

The mass spectrometer only operates under high vacuum conditions, i.e. the
pressure in the mass spectrometer must always stay below 10

-4

mbar. This vacuum

is generated by the turbo molecular pump with the support of the diaphragm pump.
The pressure pV between the two pumps is measured with a piezo resistive
measuring system and this pressure lies in the range between 4 to 10 mbar while in
the measurement mode. This pressure must not exceed a value of 10 mbar as
otherwise the turbo molecular pump will not be capable of maintaining the vacuum
in the mass spectrometer.

How the Instrument Works 2-1

2.2 Description of the Subassemblies

2.2.1 Backing Pump

A diaphragm pump in the Ecotec E3000 serves as the backing pump. All data and
further information on this pump are given in the Operating Instructions of the pump.
The backing pump generates the fore pressure required for operation of the turbo
molecular pump and sucking in of the gas through the sniffer line.

2.2.2 Turbo Molecular Pump (TMP)

Built into the Ecotec E3000 is a turbo molecular pump with upstream compression
stage. The turbo molecular pump generates the high vacuum necessary for
operation of the mass spectrometer, whereas the compression stages permits
relatively high backing pressures without impairing the ultimate pressure in the mass
spectrometer. The TMP has a side connection. Thus a part of the taken in gas is
pumped through the TMP into the first stage of the diaphragm pump. This gas load
prevents the accumulation of water vapour in the diaphragm pump.

2.2.3 Mass Spectrometer

The TranspectorTM mass spectrometer is composed of the ion source, the separator
and the ion collector. The ion source ionizes neutral gas particles and generates an
ion beam. The positively charged ions are accelerated out of the ion source and then
enter the Quadrupole field. This field acts like a filter. Only the ions to which the
system has been adjusted are able to meet the separating conditions and arrive at
the ion collector, where their presence can be measured as a current by an
electrometer amplifier. This current is the output signal which is then used to
calculate the leak rates. Two cathodes have been integrated within the ion source. If
one cathode fails the other is selected automatically.

2.2.4 Quadrupole Supply

This subassembly generates all the voltages and currents required for operation of
the mass spectrometer. Faults in the mass spectrometer are detected and signalled
to the control assembly. The control assembly monitors the mass spectrometer
supply.

2.2.5 Control

The control assembly (microprocessor) is the central assembly of the Ecotec
E3000’s electronics. All other subassemblies are controlled and monitored by this
assembly. The microprocessor which is located here is thus continuously informed
about the status of the entire Ecotec E3000 and can respond accordingly. In order to
accept commands from the operator and to output measured values and messages,
the control subassembly is linked to the display unit.

The external display unit also offers four buttons:

• The START / STOP buttons have no function (the external display unit may also
be used with other INFICON leak detectors which need these buttons)

• The MENU button will open the software menu.

• The ZERO button will set the current background reading to zero. (For details on
the ZERO function see Section 4.4.1)

The probe handle also offers some LEDs in the flange of the sniffer tip in order to
illuminate the location currently being leak tested.

Do not stare into the LEDs intentionally for extended times or at a close distance as
this may cause permanent damage to the eye.

The LEDs offer some bundled light. The intentional starring suspends the lid closing
reflex and also the eyes do not move anymore which may lead to overheating of the
retina.

When looking into the LEDs „incidentally“ the eye is protected by the lid closing
reflex. Also the permanent movement of the eyes prevents overheating and
consequent damage of the retina.

Next hold the tip of the sniffer as close as possible to the suspected leak, if required
the tip may even touch the test object.
If a welded seam or alike needs to be tested, the tip should be moved at a velocity of
no more than 10 cm/s (4 inch per second) along the welded seam. The distance
between tip and test sample should be as small as possible.

If a leak is detected the bar will grow. The Ecotec E3000 continuously compares the
measured leak rates with the programmed trigger levels.
If the trigger is exceeded the background color of the probe display will change from
green to red. At the same time an alarm sound will be released by the speaker in the

3.4.2 I•Guide Operating Mode

The I•Guide operating mode has been introduced to support the operator in applying
proper sniffer leak detection technique.

The I•Guide operator guiding mode allows to store pre-programmed parameters for
different units under test. The number of locations that need to be tested per
specimen, the time each location needs to be tested for as well as the time required
to move to the next location may be programmed. In addition, a maximum allowable
global leak rate for the total unit under test is stored. In the I•Guide mode up to 10
pre-programmed testing procedures can be stored.

Notice: If the number of locations to be tested is set to 0, the Ecotec E3000 will

operate in a continuous mode without checking for a global leak rate but
still issue the timer signal for proper testing.

3.4.2.1 Starting the I•Guide Mode

To start the I•Guide Mode go to the main menu and choose SETUP I•GUIDE. In the
opening menu go to the top line item and change the setting to

3.5 Calibration and Self-Test

The Ecotec E3000 can be calibrated internally with the built-in ECO-Check reference
leak or externally with an external calibrated leak (Cat. No. 122 20 - 122 35).

The built-in ECO-Check reference leak can be used for a self-test of the Ecotec
E3000 as well as for calibration of gases that are measured at mass positions
between 40 and 105 amu. If a gas is measured on a mass position below 40 amu or
above 105 amu it will be permitted for internal calibration in the “

A ECO-Check reference leak (cat. no. 521-001) maybe connected to the Ecotec
E3000 remotely and be used for internal calibration and verification of the calibration
(proof function) for helium and hydrogen. Internal calibration and verification may be
performed accordingly.

Notice Do not calibrate the Ecotec E3000 during the first 20 minutes after start-up.

Also a verification of the calibration may lead to wrong results in the first 20
minutes after start-up.

Only confirm and continue with the calibration or proof, if the real warm-up
time has been longer than 20 minutes (e.g. after a quick restart of the
Ecotec E3000)

Notice: When detecting hydrogen a longer warm-up time is required. For hydrogen

please calibrate the Ecotec E3000 not before 1 h after start-up.

EDIT GAS” menu.

Notice: The accuracy of an internal calibration is less than the accuracy of a

calibration with an external calibrated leak.

Notice: The ECO-Check reference leak is a temperature compensated leak. It

must only be used when electrically connected to the main unit, either
when inserted into its port or when connected to the main unit via a Sub-C
extension cord. The leak rate printed onto the body of the ECO-Check is
only valid at 20°C (68F) and will vary greatly with temperature.

To compensate for this the ECO-Check reference leak is equipped with a
temperature sensor and a compensation curve is stored in the software
which automatically compensates the test leak rate for changes in
temperature when connected to the main unit.

A calibration or verification with the ECO-Check reference leak not being
connected to the main unit will cause a wrong calibration of the Ecotec
E3000 and / or will lead to wrong testing results.

3.5.1 Verifying a calibration (proof function)

Notice: The description of how to perform a verification applies to the use of the

ECO-Check reference leak for detecting helium or hydrogen (forming gas)
accordingly.

Notice: A verification can only be performed while the Ecotec E3000 is in

measurement mode (not when the main menu is opened or during start­up).

If the sniffer tip is inserted into the opening of the ECO-Check reference leak a
verification of the calibration (proof function) will be started automatically.
While holding the sniffer tip in the test leak opening, the Ecotec E3000 will check the
reading from the ECO-Check. Afterwards the operator will be requested to remove
the sniffer tip from the leak opening.

Notice: Any time during the verification procedure an internal calibration may be

started by pressing either the right sniffer probe button or the CAL button
on the main display.

The results of the verification will be displayed in a summarizing screen.

Fig. 3-18 Results of proof function

For gases that are enabled for internal calibration either “Check ok” or “Recalibration
required” will be stated.
For gases that are disabled for internal calibration “Gas disabled” will be stated.
For gases that cannot be calibrated with the ECO-Check because of very high or
very low mass positions, “gas specific check impossible” will be listed.

For returning to the measuring mode, please press the right probe button or press
“

While holding the sniffer tip in the test leak opening, the Ecotec E3000 will first look
for a baseline, find the Argon peak of the air and then measure the test leak.
Afterwards the operator will be requested to remove the sniffer tip from the leak
opening.

After completion of the calibration a screen summarizing the results of the calibration
will be displayed.

Please hold the sniffer tip to the outlet of the external calibrated leak. Hold the sniffer
tip steady and very close to the opening, however, do not clog the opening with the
sniffer tip.
Some air also needs to enter the sniffer tip in addition to the refrigerant from the
external calibrated leak. If the leak rate signal indicated by the bar graph is stable
press “

OK”.

Keep holding the sniffer tip steady in front of the opening while the Ecotec E3000
reads the leak rate of the calibrated leak. During this time the text “Please wait…” will
be displayed.

When the analysis of the calibrated leak signal is completed a message “sniff air!”
will be displayed.
Remove the sniffer tip from the opening of the calibrated leak and hold the sniffer tip
into the air, as far as possible from any sources of refrigerant. Wait until the bar graph
shows a stable signal again and press “

OK” once more.

Notice: When calibrating for helium or Hydrogen, the air signal will decrease only

slowly and the time for the air signal to stabilize may be as long as 30 sec.
Please do not confirm the air signal too early, as this will lead to a wrongly
calibrated leak rate signal later.

A message “Please wait…” will be displayed until the calibration is finished. After
completion a menu page summarizing the old values as well as the new values will
come up. To activate the new calibration please “confirm to save new values”.

4.4.7 Activating the Interfering Gas Suppression (IGS)

The IGS Mode offers a mode in which interferences between R600a as the
refrigerant and Cyclopentane, Isopentane as well as any mixtures of the two will be
suppressed.
In this mode, the Ecotec E3000 will automatically differentiate between these three
gases and should compensate properly for levels of foaming agents not exceeding
50 g/a with an error of less than 1%.

To enable the IGS mode, choose R600a as the refrigerant and go to the mass menu
line. Press enter and toggle through the available masses for R600a until IGS is
displayed in the mass line item as illustrated in Fig. 4-11.

Fig. 4-11 Selecting the IGS mode for R600a

Notice: If the IGS mode is enabled, only one additional gas can be added to the list

of gases to be detected. If the IGS mode for R600a is enabled with more
than two gases being activated at this time, other gases (starting with the
highest gas number of 1 to 4) will be disabled automatically so that only two
gases are left activated.

Notice: For R600a in IGS mode and R134a as the second gas please chose mass

position 83 for R134a as otherwise there will be interference between the
foaming agent and R134a.

Notice: The IGS function should require almost no maintenance.

However, if you should notice repeating false alarms when using the IGS
mode, an adjustment of the IGS function may be required as described in
Chapter 8.2.

Normalization factor

The normalization factor is a factor that is used to transform the internal sensor
current into a leak rate signal. When setting-up a user-definable gas, please try to
calibrate the Ecotec E3000 afterwards with an external test leak. If the calibration is
successful, do not change the normalization factor. If the calibration process is not
successful and the error message “Calibration factor too high” is displayed, please
decrease the normalization factor by one decade, e.g. from 1.0E+08 to 1.0E+07. If
the error message “Calibration factor too low” is displayed, please increase the
normalization factor by one decade, e.g. from 1.0E+08 to 1.0E+09. Repeat this
process until the Ecotec E3000 is successfully calibrated.

LOWER FLOW LIMIT is set to the actual gas flow (160 sccm) the more

sensitive the Ecotec E3000 will respond to beginning clogging of the filters and the
sniffer line itself.
The closer the

UPPER FLOW LIMIT is set to the actual gas flow the more sensitive the

Ecotec E3000 will respond to damages to the sniffer line.
The

LOWER FLOW LIMIT can be set to values between 0 and 160 sccm.

Default value is 100.
The

UPPER FLOW LIMIT can be varied between 160 and 999 with a factory default

value of 250.

Fig. 4-13 Changing the flow limits of the sniffer line

Notice: The flow through the sniffer line depends on the atmospheric pressure. If

operated at high altitude the flow through the sniffer line may drop
significantly (approx. 20% per 1000 m [3000ft] altitude). In this case, please
adjust the flow limits accordingly.

Sensitivity check

S

ENSITIVITY CHECK is a monitoring function which will help to ensure that the

sensitivity of the Ecotec E3000 will always be sufficient.
In the

SENSITIVITY CHECK submenu the sensitivity check can be enabled or disabled.

With this setting the entire gas flow from the tip of the sniffer into the sensor is
monitored and at the same the software checks the Ecotec E3000 to determine if it
in turn determines the correct signal amplitude.
Running of this function ensures that the Ecotec E3000 will not become insensitive
without this being noticed by the user.
If sensitivity changes, E30 will be displayed. In this case, please recalibrate the
Ecotec E3000 to restore sensitivity (see Section 3.5). The error message will be
repeated every 15 seconds until a re-calibration is started.

Notice: It is highly recommended to always keep this function enabled. This

function should only be disabled when operating in an Argon-free
environment as the Argon signal is used for monitoring.
