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.

I•Guide Mode

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.
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 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.

Do not touch voltaged parts with the sniffer tip. Test samples need to be disconnected from electricity before leak testing.
Do not suck in any liquids.
A water-protection tip is available (Cat.-No. 12246) which will protect the Ecotec E3000 against intake of liquids if necessary. For details on how to install the water protection tip see 1.6.2)

3.4.1 Standard Operation Mode

Provided the Ecotec E3000 has been set-up to meet the requirements of the particular application and it has been calibrated (see Section 3.5), a measurement is run as follows:
First briefly operate the Ecotec E3000 eliminates all interfering influences which may affect the (i.e. the detection limit of 0.05 g/a). 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.

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 IGUIDE. In the opening menu go to the top line item and change the setting to side push button and press enabled I•Guide program in the list. A message screen will pop-up notifying the operator that I•Guide has been activated and therefore only one or two gases will be measured from now on (the gas selected in the I•Guide program you choose).

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.
3-14 Operation of the Ecotec E3000

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 “
OK” on the main display.

Fig. 3-21 Setting-up the leak rate of the external leak
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.

Default value: 69

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.

ZERO TIME can be set to values between 1.0 and 9.9 s.
Default value: 5.0 s

Flow limits

In this submenu the minimum and maximum gas flow through the capillary is entered. If the actual gas flow drops below this limit (e.g. if the capillary becomes partially blocked) or exceeds this limit (e.g. if the sniffer line is damaged so that ambient air is sucked in) an alarm is issued. The closer the
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.

Recorder output scale

LIN The voltage range spans from 0 V to 10 V.
The leak rate which is output is normalized with respect to the trigger level for the corresponding gas. The trigger level will correspond to an output of 1 V. Higher and smaller leak rates may be output as a voltage deviating by a corresponding factor with reference to the trigger level.
Example: The trigger level of the corresponding gas has been set to 3 g/a.
