Impact / Impact Pro / Impact Pro IR Operating Instructions

1� Introduction

The Impact Series is a compact, portable gas monitor designed to be carried or worn without hindering the user. Its purpose is to monitor the atmosphere continuously for hazardous levels of up to four gases. Audible and visual alarms alert the user to danger when hazardous conditions are detected.

The instrument is usually supplied with four gas sensors, for detecting oxygen (enrichment and deﬁciency), ﬂammable gases (up to the Lower Explosiv e Limit) and two toxic gases (for personal safety) all housed in an easily replaceable cartridge. An alternative arrangement using infrared sensors for ﬂammable or carbon dioxide is also available.

Various sensor technologies are used to achieve this. In the vast majority of cases, electrochemical technology is used to detect oxygen and toxic gases while catalytic combustion technology is used to detect ﬂammable gases. Infrared technology is used to detect ﬂammable and carbon dioxide gases.

Two types of cartridge are available. One is disposable where the cartridge has a ﬁxed life and once this has expired the cartridge is disposed of. The other is a Serviceable Cartridge where the sensors can be individually replaced when required. The serviceable cartridge type can only be used in the Impact Pro.

Note

Throughout this manual it is assumed that the Impact Series is equipped with a Disposable Four Sensor Gas Cartridge. References to sensors not

ttedintheusersinstrumentshouldbeignored.

This manual covers all models - some features are not available on all models. Not all models are available in every country.

The instrument is supplied with dry cell batteries and holders as standard. Rechargeable batteries and charger can be purchased separately as a kit.

1�1 Intended Use

The Impact Series has been designed to alert the user to potentially hazardous atmospheres while carrying out his/her normal duties. Therefore, the instrument must be kept switched on and worn as close to the breathing area as possible, and several accessories are provided to allow the instrument to be worn in a number of different ways:

On the chesta)

On a beltb)

Attached to a body harnessc)

The instrument is provided with various methods to enable the user to comply safely and easily with conﬁned space regulations.

CAUTION

Hand aspirated remote sampling only provides continuous gas readings as long as the bulb is being operated.

Honeywell Analytics recommends that the instrument be calibrated at least every 6 months or in accordance with customer site procedures, whichever is sooner.

Ensure the Base Station is connected to a suitable power source.1.

Place the instrument in the Base Station.2.

The Base Station employs a locking mechanism to ensure that the Impact is

retained under most operating conditions. To ensure this operates correctly

the following procedure should be followed:

Ensure that the Impact is oriented such that the instrument lip will be a) inserted under the locking lip.

Insert the front of the Impact at an angle such that the instrument lip b) slides under the locking lip.

In normal operation the Impact is worn on the belt, with its harness, or held by hand. Once turned on the Impact monitors the atmosphere continuously, which reaches the sensors by diffusing through the vents of the cover grille or by being pulled through by the internal pump (if ﬁtted). For non-pump instruments normal air movements are sufﬁcient to carry the sample to the sensors, and the sensors react immediately to changes in concentrations of the gases being measured in the atmosphere immediately surrounding the detector. Depending on your application and the options ﬁtted to the instrument the environment can be sampled remotely in a variety of ways, as summarized below:

CAUTION

Hand aspirated remote sampling only provides continuous gas readings while the bulb is being squeezed. Each time a reading is required, it is necessary to squeeze the bulb at a rate of one per second until the readings remain stable.

When using the built-in pump or hand aspirator ensure that the sampling tube is

notinsertedintoauid.

2�5 How to turn Impact Series on and off

The Impact has been designed for ease of use, and especially for one-handed operation - only a single button is needed to turn it on and off.

To turn the instrument on, press the • button until the instrument activates

its audible and visual alarms. It will follow the start-up sequence described

in Section 3. Instrument Start-up.

If the instrument displays an error that no cartridge is ﬁtted then follow the procedure in Section 2.1 Inserting the Cartridge.

20

To turn the instrument off, press and hold the • button for three seconds,

until it switches off. Note that on some models a password must be entered

to switch the unit off. Failure to enter the correct password will cause the

instrument to continue as though the button had not been pressed.

fresh air?

� -Yes, -No

If enabled, the instrument will prompt if you wish to zero the sensors in fresh air, to adjust for any natural drift that may have occurred. If the 3 button is pressed the instrument will then ask the user to ensure that it is being zeroed in fresh, uncontaminated air. If the button is not pressed within ﬁve seconds, the instrument will automatically proceed to the next stage in the power-up sequence.

If the 3 button is pressed the instrument will attempt to zero the sensors automatically, and display whether the procedure was successful. The oxygen reading will be adjusted to 20.9% v/v – the other sensor readings will be adjusted to 0 ppm and 0% LEL appropriately. If the button is pressed instead the instrument will use its current zero values instead and proceed to the monitoring

screen.

Note

This is a ‘soft’ (i.e. temporary) zero which will be discarded when the instrument is switched off. To permanently adjust the zero, the zero via the calibration menu must be used (‘hard zero’). See Section 4.9.2.1 for details.

3�4 Sensor Warm-up Phase

Following display of the Autozero screen it will be noted that the message ‘Cell Self Test Please Wait’ is displayed. This is displayed while the sensors are in

the warm-up phase of the start-up procedure. If the option of Autozero is declined the main gas measuring screen will be displayed with the message ‘Warm Up’ being displayed in place of the gas concentration readings. The instrument should not be used until the ‘Warm Up’ message has disappeared. The amount of time that the sensors are in warm up will depend on the sensor type. Table B.3.1 in Appendix B of this manual gives details of the warm up times for each of the sensors.

3�5 Testing Sensors and Alarms (Calibration and Bump Checks)

To maintain accuracy, the detector should be periodically supplied with a known concentration target test gas (calibration check) and if the readings differ from the applied gas concentration by more than 20%, a span calibration should be performed under conditions of standard temperature (15°C to 25°C/59°F to 77°F), humidity and pressure. Follow local regulations and your company’s policy on the frequency of testing.

Note:

If the target gas is not available in a known concentration, or is not available for testing and a surrogate gas is used, the 20% tolerance value will not apply. In this case, verify that the instrument responds to the applied gas and triggers alarms (bump test).

If using the Enforcer for calibration checking or bump testing, refer to Section

4.9.4.

For more information on test gas, contact your local Honeywell Analytics representative.

4�1�2 Other Displayed Symbols

If the pump is operating correctly the pump symbol will

rotate.

If the pump ﬂow becomes blocked the instrument will

warn the user and stop the pump to prevent potential

damage. When the user accepts the warning message

the instrument will attempt to restart the pump. There is

no need to remove and reﬁt the Pump Adapter. At this

point, the user should investigate the cause of the blockage alarm. If the blockage is cleared then the pump will successfully restart. If the blockage is still present then the instrument will again warn the user that the pump ﬂow is still blocked. This will repeat until the blockage is removed.

This shows an approximation of the remaining battery capacity within

the instrument. If there is less than 20 minutes remaining battery life

then the instrument will display a ‘Low Battery’ warning.

This will be shown instead of the numerical reading for any sensor or channel that is faulty, if a zero or span calibration has failed, in instances of low oxygen and in some cases of high gas concentrations. Switch the instrument off and then back on. If this does not clear the fault then recalibrate the sensor or change the cartridge.

This indicates that the sensor output of the indicated channel has

Impact / Impact Pro / Impact Pro IR Operating Instructions

4�1�3 Conﬁdence Signal





To ensure correct operation the instrument monitors itself and will conﬁrm correct operation by giving an audible and green visual conﬁdence signal once every 30 seconds. The conﬁdence signal is given when the instrument is able to detect gas (for example the conﬁdence signal will not be given during pump or sensor calibr ation phases, or if the sensors are in warm-up).

There is a conﬁgurable option to silence the audible conﬁdence signal but the visual conﬁdence signal will still operate. If the instrument is in a low battery condition the conﬁdence signal will occur twice every 30 seconds.

Note

The audible confidence signal is the primary indication that the instrument is functioning correctly. It is therefore strongly recommended that this feature not be disabled.

4�1�4 Go/No Go Option

A conﬁgur able option is available which replaces the numeric values with a 3 symbol when everything is OK and 8 when there is or has been an alarm or fault, as shown below. All alarms operate as normal, but other functions and menus are disabled.

This display now also shows the battery capacity as follows.

The Go / No Go Option is conﬁgured using the Impact Conﬁguration Utility (ICU) PC software from the Conﬁguration Screen.

There are two modes of alarm: latching and non-latching. However, the display will give the same alarm indication:

An alarm symbol will appear in the relevant section of the display. The alarm symbol contains a number, indicating the increasing severity of the alarm, with increasing frequency of the audible and visual alarms. If there is a STEL/LTEL alarm the relevant icon will appear and ﬂash.

Any alarm will cause the backlight to be switched on automatically.

4�3�1 Latching Alarms (default)

In the latched condition, once an alarm occurs both audible and visual alarms continue to operate even after the atmospheric hazard has cleared. Pressing any of the instrument buttons will clear an alarm. Any subsequent alarm will reactivate the audible and visual alarms.

4�3�2 Non-latching Alarms

In this mode, should a gas alarm occur the instrument w ould enter an alarm condition. When the readings return to normal levels the audible and visual alarms will stop.

4�3�3 Vibrating Alarm (where ﬁtted)

If this option is ﬁtted to the instrument, any alarm condition that activates the audible and visual alarms will also activate the built-in vibrating alarm.

4�3�4 Resetting an Alarm

If an alarm condition occurs it is possible to cancel the alarm by pressing any of the buttons, once the gas measurements have returned to a safe level. Otherwise, the instrument will remain in the alarm condition, but the audible alarm will be muted. Any subsequent alarms that occur 1 second after the previous alarm has been reset will reactivate the audible alarm.

4�4 Fault and Warning Condition

In addition to the gas alarms, the Impact includes a number of auxiliary alarms to safeguard proper use of the instrument. At switch-on, the Impact performs an electronic self-test that assures the user of proper performance. When the Impact detects that an electronic fault or failure condition has occurred, the audible and visual alarms are activated and an explanatory message will be displayed.

26

CAUTION

As the Impact is designed to protect from potentially life-threatening atmospheric conditions, any alarm conditions must be taken seriously.

4�5 Safelink

4�5�1 What is Safelink?

Safelink is a conﬁned space entry communication system between instruments, ﬁtted with the Safelink feature. It allows one instrument (the ‘attendant’) to display the gas readings measured by the other connected instrument (the ‘entrant’), up to a maximum cable length of 100m. Safelink also provides an automatic timed response system requiring the Entrant’s instrument to return a signal, activated by the entrant, within a user-speciﬁed time interval. Failure of the user to respond will cause an alarm to be raised on the Attendant’s instrument. Additionally, any continued pressing on any button on the entrants instrument at any time will cause an ‘Emergency’ message to appear on the attendant instrument - similar to the action of a panic button. In Safelink mode the entrant instrument can neither be switched off, nor can the pump feature (where ﬁtted) be used on either instrument. It will be found that while the pump is running the Safelink option on the instrument menu system has been removed. Furthermore, if an attempt to start the pump is made (on either the attendant or entrant instrument) during Safelink operation an alarm condition is generated and Safelink Mode has to be exited.

Safelink mode cannot be entered when the batteries are low (i.e. there is less than 1 bar on the battery indication meter).

In some instances a Fault or Warning will not be displayed on the Entrant instrument. In this case it is important to note that gas alarms on the Entrant instrument are still indicated on the Entrant and the Attendant instruments.

On one instrument select Attendant. When selecting the

Attendant on one instrument the instrument will display

‘locating’ while it attempts to connect with the other

instrument. Once established each instrument will brieﬂy

display ‘Conﬁguring’. The instrument will then show the

readings – ensure that the Safelink symbols appear on the display. To check the integrity of the communications it is recommended that a message be sent from the Attendant to the Entrant. Whenever a message must be responded, the instrument will ﬂash its green LEDs and sound its audible alarm at a rate of once per second.

Until the Safelink cable is disconnected both instruments will remain in Safelink mode.

4.5.2.1 Attendant Instrument

The instrument will display the readings being monitored

on the Entrant instrument. The symbol is used to

indicate the Attendant’s instrument. When the symbol is

static it indicates that Safelink communications are

occurring. When it is ﬂashing the Safelink has become

disconnected and the readings will all show ‘---‘, until the link is restored or the user exits from Safelink mode. All display modes from the Entrant’s instrument (peak, STEL, etc) are available to the Attendant.

The Select Message menu gives access to two additional actions:

Emergency, which immediately issues a ‘Get Out’ warning to the Entrant.a) Exit, to enable termination of the Safelink without removing the cable.b)

4.5.2.2 Entrant instrument

The symbol is used to indicate the Entrant’s instrument. When the symbol is static it indicates that Safelink communications are occurring. When it is ﬂashing the Safelink has become disconnected.

Only the instantaneous values are shown, although all alarm conditions will operate as normal.

Impact / Impact Pro / Impact Pro IR Operating Instructions

The status screen shows the duration that Safelink has

been in operation, and the status of the connection as

either Normal, Emergency, or Link failure.

4.5.2.3 Timed Response

At a preselected interval the attendant’s instrument will prompt for the Entrant to be checked. The Entrant must press any button within a preselected time, otherwise the Safelink system will assume an emergency situation has occurred and raise alarms on both instruments. The default interval is 5 minutes. The default time to respond to a message is 30 seconds. Both of these can be changed using the PC software.

4.5.2.4 Terminating Safelink

To terminate Safelink mode the cable should be

disconnected between the instruments. Both instruments

will display a menu enabling Safelink mode to be switched

off.

Safelink mode must be terminated before attempting to use the instrument in a Base Station (for charging or calibration) or the Enforcer.

4�9 Calibration

The accuracy of the Impact instrument should be checked with known concentration calibration gas before each day’s use. If any sensor fails recalibrate the Impact before using, or replace the cartridge. It is recommended that the instrument be calibrated at least every 6 months. The calibration interval for the CO not exceed 1 month.

The Impact instrument provides three methods of calibration, offering ﬂexibility for the user. Flow calibration is the traditional method and can be performed, following instructions displayed on the instrument itself (Section 4.9.2 Flow Calibration – Instrument), or when the instrument is connected to a PC via a Base Station, on the PC display (See Section 4.9.3 Flow Calibration – PC). An alternative method for instruments ﬁtted with a combination of oxygen, ﬂammable, carbon monoxide and hydrogen sulﬁde sensors only is to use the Enforcer accessory. For all other gases the ﬂow calibration method must be used.

CAUTION

Use of non-standard calibration gas and/or calibration components when calibrating the Impact can lead to dangerously inaccurate readings.

The calibration should be carried out in a well-ventilated area to avoid contaminants.

Do not calibrate the electrochemical sensor CO clean air after the apparatus has been exposed to CO upper limit of the measuring range. In this case leave the instrument in clean air

Oxygen sensors may be affected by prolonged exposure to carbon dioxide, and it is recommended the Impact not be subjected to use in atmospheres containing more than 25%v/v carbon dioxide (CO2). Oxygen sensors may read high in the presence of carbon dioxide.

Flammable sensors may be affected by exposure to Silicone substances; organic phosphorus containing compounds and halogenated organic compounds. Although the ﬂammable sensors used in Impact and Impact Pro have a high resistance to Hydrogen Sulﬁde (H2S) poisoning some loss in sensitivity should be expected. Therefore it is strongly recommended repeated gassing with H2S or gas alarms on the H2S channel should be followed by checking and if necessary re-calibration of the Flammable sensor. The sensors on average will lose approximately 20% of their sensitivity when subjected to forty applications of H2S for a period of 1 minute each.

The toxic sensors are designed to be gas speciﬁc, minimizing the effects of common cross-interfering gases. The table below summarizes the effect of various gases on the Carbon Monoxide and Hydrogen Sulﬁde sensors.

4�9�4 Enforcer Calibration

This is designed for oxygen, ﬂammable (catalytic or IR LEL sensor), carbon monoxide and hydrogen sulﬁde, using a special-to-type gas cylinder. It offers quick, simple and safe operation by any user, due to the use of a patented low pressure, low ﬂow rate system.

Note that the Enforcer cylinder contains dangerous gases.

Performing a Calibration Check with Enforcer

To perform a calibration check of your Impact unit using the Enforcer, power the unit on and place it into the Enforcer and follow the on-screen instructions (see Section

4.9.4.1 Enforcer On-Screen Instructions). Then re vie w the peak readings as shown in Section 4.1.1 Peak Screen.

Performing a Bump Test with Enforcer

To perform a bump test of your Impact unit using the Enforcer, power the unit on then place it into the Enforcer and follow the on-screen instructions (See Section 4.9.4.1 Enforcer On-Screen Instructions). A bump test is a check of basic functionality (not a calibration check), so the Impact unit need not remain in the Enforcer for the full ninety seconds; 30 seconds is usually sufﬁcient. Remove the Impact and check that all the ﬁtted sensor channels are showing alarms, and that the visual (red ﬂashing lights) and audible alarms are active.

If there is any doubt about the bump test result, carry out a calibration check as described above, or a full calibration as described below.

Performing full Calibration with Enforcer

Power up the instrument and perform a ‘hard zero’ (using the zero on the calibration menu - see Section 4.9.2.1 Zero) then follow the steps in Section 4.9.4.1. If the Enforcer calibration is successful, the unit will automatically update the next calibration required by date by the predeﬁned calibration interval value (default 180 days).

Note:

If the ’Hard Zero’ is omitted then the calibration is retained only for the current session and the calibration date will not be updated.

4.9.4.1 Enforcer On-Screen Instructions

If it is not already ﬁtted, screw the Honeywell Analytics cylinder in tightly 1. (multi-gas mix for Enforcer), check that the pressure gauge shows gas pressure is present, and pull back the instrument drawer.

Insert the instrument, by tilting at a slight angle, so that the instrument 3. front cover locks under the cover lip in the Enforcer as indicated.

Then return the instrument to the vertical. The rear locking mechanism 4. of the Enforcer will retain the instrument. Now close the drawer ﬁrmly.

When 3 is pressed, the user should hear the distinctive ‘click’ of the Enforcer gas delivery solenoid valve.

After about 90 seconds the instrument will display either a pass or fail.6.

If the instrument reports a failure then check that the gas cylinder has 7. sufﬁcient pressure. Then repeat once more. Note that the instrument drawer must be opened and then closed to reactivate the Enforcer. If a subsequent failure should occur please have the instrument serviced and calibrated, as it may be due to blocked or dirty ﬁlters, or the sensor(s) has failed.

When completed and successful remove the instrument by pressing 8. downwards on the rear locking catch and lifting the instrument out. The instrument will activate all its gas alarms as it detects the gas from the cylinder, thereby also performing a bump test.

The cylinder should be removed after use. The instrument automatically switches to a ﬂammable gas setting of methane while

in use with the Enforcer. On completion it will revert to the ﬂammable gas that the instrument is set to measure. No intervention by the user is required.

5� Fault Finding and Procedures

There are two levels of fault within the instrument. The ﬁrst level is a warning, from which the user may be able to recover, e.g. a low

battery. The user must press the 3 button to conﬁrm the warning has been seen. The second level is usually non-recoverable by the user, and in some cases the

only action available is to switch the instrument off. In both cases a warning/fault code number is given with a brief description of the

fault, and a contact name/telephone number to enable the user to further assistance if required. Details of the warning and fault codes are given in Appendix A.

7� Routine Maintenance

The Impact Series is designed to operate almost maintenance free under most conditions, except for the need for regular calibration. However, it is recommended that on a regular basis the instrument is cleaned and the ﬁlters changed.

7�1 Cleaning

The instrument may need cleaning if exposed to dirty or hostile conditions. This can be easily achieved by wiping over with a damp cloth. Do not use bleaching products or products containing silicon compounds as these can cause damage to the sensors.

7�2 Filters

The Gore-tex ﬁlter ﬁtted under the cover grille is man ufactured from a water repelling material to protect the sensors from the ingress of water and other contaminants. The life of this ﬁlter is dependent on the amount of dust and viscous liquids in the atmosphere. If it becomes dirty (discolored) it will act as a barrier and prevent the diffusion of the atmosphere onto the sensors, and must be replaced. This is easily achieved by removing the cover grille screws (Section 1.2 Product Overview (5)), discarding the old ﬁlter and ﬁtting a new ﬁlter, using the molded detail to locate it.

Note that for instruments ﬁtted with a chlorine sensor a stainless steel ﬁlter (part number P2302D0823) must be used instead of the Gore-tex ﬁlter.

7�3 Battery Charging / Replacement

WARNING

Battery Charging and replacement must not be carried out in a hazardous or potentially dangerous area.

A mixture of dry cell and rechargeable battery packs must not be used - the instrument safety system prevents operation in such a situation, and the instrument displays a fault message and activates the audible and visual alarms.

Special Notes for IR Sensors

The Impact Pro IR offers many beneﬁts that enable the user to achieve drift-free operation and longer-term stability, when compared with catalytic bead (pellistor) or photo ionization detectors (PID). IR sensors are immune to poisons such as silicones that can contaminate Catalytic sensor types. IR sensors can detect hydrocarbon gas levels in the absence of oxygen (O with catalytic bead sensors. Typical applications would be to measure hydrocarbon gases under nitrogen storage blankets or other inert atmospheres. IR sensors generally enable users to achieve their application requirements with an overall lower cost of ownership

There are three (3) types of infrared sensor that can be ﬁtted; two for ﬂammable gas (%LEL and %Vol options), and the third for Carbon Dioxide (CO IR sensor can be installed per cartridge. Both IR ﬂammable sensors are calibrated for methane, although they will be sensitive to many hydrocarbon gases. Please note the following:

Hydrogen (H

) cannot be detected using the IR principle.

By default, no alarms are provided for the 0-100%/Volume IR sensor. The user can setup alarm levels via the ICU software.

Compatibility

The settings for the new IR sensor are stored in the smart cartridge. Those i) cartridges that house the new IR sensors have a slightly modiﬁed internal arrangement. Existing Impact Pro models will need to be returned to an approved service center to make sure the ﬁrmware is current and to get updated certiﬁcation and notiﬁcation labels applied. In addition, earlier models of Impact Pro will have to have modiﬁcation of the cartridge-mounting boss. New Impact Pro IR units ordered will be conﬁgured with the appropriate labelling prior to shipment (see part numbers below). Contact your approved Honeywell Analytics Service Center for full details of this modiﬁcation.

It is the user’s responsibility to ensure that the ﬂammable gas settings are not changed from methane for IR ﬂammable sensor cartridges.

The latest version of this utility (3.0 or later) is designed for this IR series. This revised version of this utility provides for the IR gases and ranges and prevents selection of Hydrocarbon gases other than Methane, as could be done with the standard Impact employing a catalytic bead. The operator must ensure that if an IR ﬂammable cartridge is ﬁtted, only the new ICU (3.0 or later) is utilized for Downloading/Uploading of the instrument.

extremely small concentrations of gas (low or

sub ppm) or one speciﬁc gas in the presence of

several others. Gas Detector or Monitor Refers to equipment designed to alert the user to

potentially hazardous concentrations of gas in the

monitored atmosphere. Hard Zero When a hard zero is performed using either the

built-in calibration menu or the PC software then

any adjustments will remain in place when the

instrument is turned off. Performing a hard zero

followed by an Enforcer calibration, instrument

menu span or PC calibration will adjust the

calibration and change the calibration due date.

Hazardous Areas Areas where there is the possibility of the

presence of an explosive mixture of ﬂammable

gas or vapor and air are known as ‘Hazardous’

and other areas as ‘safe’ or ‘non-hazardous’. Any

electrical equipment used in hazardous areas

must be tested and approved to ensure that, in

use even under fault conditions, it can not cause

an explosion.

In Europe, hazardous areas are defined as

follows:

Zone 0: An area where an explosive mixture is

likely to be present at all times, under normal

operating conditions.

Zone 1: An area where an explosive mixture is

likely to occur in normal operation.

Zone 2: An area where an explosive mixture is not

likely to occur in normal operation, and if it does

it is only for short periods.

In the US, hazardous areas are classiﬁed in 2

divisions:

Division 1: Equates to Zone 0 and Zone 1

Division 2: Equates to Zone 2

Intrinsically safe Approval by an appropriate authority to use the

instrument in hazardous area. IP Ingress Protection – a measure of protection

against the ingress of dust and water IS See Intrinsically Safe LED Light emitting diode. LEL Lower Explosive Limit – is the lowest concentration

of ‘fuel’ in air which will burn and for most

ﬂammable gases and vapors it is less than 5%

by volume. LEL% Percentage of the Lower Explosive Limit (for

example, 10% LEL of methane is approx 0.5%

by volume). LTEL Long Term Exposure Limit. The 8 hour LTEL is

the time-weighted average concentration for a

normal 8 hour day to which most workers may

be repeatedly exposed, day after day, without

adverse effect. Also known as TWA. MED Maritime Equipment Directive Oz Ounce (weight).

– A very small sensing element used in catalytic

sensors and sometimes also called a ‘bead’ or a

‘siegistor’. Poison resistant Capability of a catalytic sensor to reduce the

effect of inhibiting substances or contaminants,

such as silicones. PPB Parts per billion concentrations in the

atmosphere. PPM Parts per million concentrations in the

atmosphere. RFI Radio frequency interference. Safe Area Work area in which there is no danger of

contamination with explosive gases. Soft Zero When a soft zero is performed (i.e. the autozero

on startup) any adjustments will only remain in

place while the instrument remains switched on.

Performing a soft zero (autozero) followed by

an Enforcer calibration or instrument calibration

menu span (i.e. not a menu zero ﬁrst) will adjust

the calibration while the instrument remains

switched on but will not change the calibration
