Introduction to PhoCheck+_
________________________________________
PhoCheck+ is a portable gas detector, suitable for the detection of a large range of Volatile Organic
Compounds (VOC's), which are dangerous from both a poisoning and explosive perspective. Total VOC‟s are
detected using PID (Photo Ionisation Detection) technology.
The PhoCheck+ versions are fully upgradeable in the field (i.e. PhoCheck+ 1000 to a 5000 or a 2000 to a
3000 etc). See page 37 for more details relating to upgrade options.
PhoCheck+ has two principle modes of operation; Survey and Health & Safety. Health & Safety mode is
available on 3000 and 5000 versions.
Survey is the default mode of operation. This mode is often used in applications such as Head Space
Sampling and Leak Detection where several areas (or Zones) are to be monitored and readings data logged.
All sensor readings are real time measurements and alarm levels are set manually.
Health & Safety mode is used to check for conformity of short-term exposure levels (STEL) or time-weighted
averages (TWA) that are specific for particular hazardous environments (for example EH40 in the UK and
OSHA in the USA). In this mode of operation STEL's and TWA's are continually calculated and compared to
levels set in the instrument‟s gas table. For more information on these modes of operation please see page
19.
PhoCheck+ versions 2000, 3000 and 5000 automatically data log the readings every second. These readings
are stored in the instrument's memory with a date and time stamp. For more information please see page
18.

Getting started _____
1. Rechargeable Batteries
PhoCheck+ instruments leave the factory fully charged, however prolonged periods of storage may result in
the battery pack discharging. We recommend charging the instrument for 12 hours before use. See the
battery section of this manual page 28.
2. Alkaline Batteries
Fit the battery pack supplied with the PhoCheck+. For more information please see the battery section of
this manual page 28.
3. Selecting a gas from the internal gas table
PhoCheck+ instruments leave Ion Science pre-set for gas type TVOC (total volatile organic compounds).
Instruments are factory calibrated against isobutylene and all response factors are equivalent to this. By
changing the gas from the gas table all readings will be given using that gases response factor. To change
the selected gas please see page 18.
Turn the instrument on by pressing the key.
Press and hold the key and check the correct gas, alarm levels and zero mode are selected.
The screen will flash for 1 minute while the detector warms up – check for a reading on the display
Between 0.2ppm and 2ppm.
Replace the probe and filter with the blue carbon filter – check for a reading from 0.0 to 0.2ppm.
Remove the carbon filter and replace the probe and filter.
If the results are not as expected, perform a custom calibration first ensuring the correct gas is
selected.
4. Setting alarm levels
We recommend that alarm levels are set to user specifications as soon as possible before being used for the
first time. Please see page 16 for details of how to set alarm levels.
5. Setting date and time
We recommend that the correct local date and time be set to the instrument as soon as possible before
being used for the first time. Please see page 18 for details on how to set the date and time.

In the Tools Menu use the UP and DOWN keys to find the function you require. To select the function, press
the ENTER key.
Data Logging, Zones & Files (PhoCheck+ 2000, 3000 & 5000)
PhoCheck+ automatically data log the instruments readings every second. These readings are stored in the
instrument's memory with a date and time stamp. The instrument has been designed to continuously store
data; once the memory has reached its full capacity (8 Mb) it will automatically begin to overwrite previous
readings. An alarm can be set (see page 16) to inform the user that this is due to happen, giving time to
download any data that may be over written.
Stored data can be viewed on the PhoCheck+ instrument or it can be downloaded to a PC for analysis and
to be archived. Ion Science recommends downloading saved readings once a week.
In some applications readings need to be recorded in many different locations leading to many hundreds of
stored files. PhoCheck+ was designed with these requirements in mind and has the facility to store files into
ZONES. The PhoCheck+ has a default Zone called Zone 0 (which can not be deleted), unless specified all
readings will automatically be stored under this Zone. The PhoCheck+ has an additional 199 Zones which
the user can name themselves, either direct via the instrument or by using the IonPC software.
View Data (PhoCheck+ 2000, 3000 & 5000)
This function allows the stored data to be viewed or deleted
First select the Zone of interest by moving the cursor using the
UP and DOWN keys, press ENTER to select it.
Then select the required File in the same way. Now select the View Data symbol,

Alarm (PhoCheck+ 1000, 2000, 3000 & 5000)
When in SURVEY mode, upper and lower alarm
levels can be set by the user to indicate particular
levels of detection specific to their needs.
Both alarms give an audible and visible output (flashing LED) but with increased urgency with the upper
alarm. An alarm state indicates that PhoCheck+ has detected the user set alarm level which has been
exceeded. The alarm will continue to sound and flash until the user acknowledges the alarm by pressing
ENTER. Please note that it is the user’s responsibility to respond appropriately to an alarm
condition.
Upper and lower alarm levels in survey mode are simple to set via the instrument. Use the up and down keys
to select the Alarm graphic in the function menu and press Enter. Then select the alarm you wish to adjust
(Upper or Lower), press enter again then use the up and down keys to change the alarm setting. These
alarms can also be easily adjusted on a PC via the Gas Table in the IonPC software. Please note that for
safety reasons the lower alarm cannot be set above the upper alarm and the upper alarm cannot be set
below the lower alarm.
When in Health and Safety mode, alarms are triggered by STEL and TWA alarm levels pre-programmed
into the instrument‟s gas table. An Alarm in Health & Safety mode indicates the user has been exposed to
levels exceeding those set within the gas table. When PhoCheck+ alarms in Health and Safety mode, the
relevant TWA or STEL figure shown on the display will flash. These values cannot be changed either via the
instrument or the IonPC software.
Sound (PhoCheck+ 1000, 2000, 3000 & 5000)
Audible outputs can be selected to indicate
functions. When Signal is selected, the rate at
which the instrument BEEPS increases with the detected gas. When Confidence is selected the instrument
BEEPS every few seconds to indicate it is functioning. This feature can be useful if the instrument is out of
sight. When Key is selected the instrument BEEPS when a key on the keypad is pressed. Alarm can only be
adjusted using the IonPC software to avoid the accidental switch off.
Calibration (PhoCheck+ 1000, 2000, 3000 & 5000)
'Factory calibration' is set by Ion Science during
instrument manufacture. 'Custom calibration' can be
set by the instrument user.
General description
Due to the linear output of the Ion Science PID detector , PhoCheck+ instruments only require a two-point
calibration. The PhoCheck+ scales its linear output across a ZERO level (clean air reference) and the SPAN (a
user defined gas concentration).
Factory Calibration
'Factory' calibration offers a safe set of calibration data. This should be used if the custom calibration fails
and will keep the unit working until a good custom calibration is completed.
ION Science recommends an annual service and calibration for users who require a traceable calibration.
During this service the lamp and detector is brought back to factory specifications and new Factory
Calibration data is stored.

be used. Note – the carbon canister simply pushes onto end fitting - do not force
and no turning is required.
4. Press the Enter key to start the ZERO process. A counter will count down showing
how long the canister needs to remain connected.
5. At the end of the count down a tick '' will appear, indicating that the Zero has
been accepted. Press Escape.
6. Disconnect the carbon canister and replace the cap ends. The useful life of the
carbon canister will be shortened if the canister is open to atmosphere for
prolonged periods.
7. Scroll down and select the flashing VOC.
8. The next screen shows the gas and gas concentration you have previously set up
via the IonPC software. Select Enter.
9. A screen will show VOC, a gas bottle and a flashing highlighted number.
10. Present the instrument with the calibration gas and press enter, the number will
begin to count down showing how long the instrument needs to be presented
with the gas. A tick '' will appear indicating that the calibration has been
accepted. Escape out of the calibration menu.
11. Now replace the instruments filter and probe ready for use.
12. Carry out a Bump Test to ensure calibration was successful. Instrument is now
ready for use.
If you are not successful in calibrating the instrument check the following points:-
The carbon canister may be contaminated
The calibration gas may be low or empty
If using a connector pipe there may be a kink restricting the flow of gas
PID lamp may require cleaning
PID lamp may need replacing

(Milligrams per cubic meter).
NB: the ppb option is available on the PhoCheck+ 5000 and is upgradeable on the 1, 2 and 3000 versions.
This menu option is also available on the IONpc software.
Data Log Memory Alarm (PhoCheck+2000, 3000 & 5000)
PhoCheck+ has been designed to continuously store data. Once
the memory has reached its full capacity (8 Mb) it will
automatically begin to over write previous readings. An alarm can be set to inform the user that this is due
to happen giving the user time to download any data that may be over written if they wish to do so. This
menu option is also available on the IONpc software.
Application - Survey Mode (PhoCheck+1000, 2000, 3000 & 5000)
SURVEY is the default mode of operation whenever the HEALTH & SAFETY mode is NOT selected. All
functions can be adjusted or selected in this mode unless the SECURITY mode is set via the IonPC software.
SURVEY mode is often used in applications where several areas (or Zones) can be monitored and readings
data logged. Saved data can then be downloaded to a PC for long-term storage and review. High and low
alarm levels can be set.
Application - Health & Safety Mode (PhoCheck+3000 & 5000)
Modes of operation are selected to suit how the instrument is
being used. Health & Safety mode is used to check for
conformity of short-term exposure levels (STEL) or time-weighted averages (TWA)
that are specific for particular hazardous environments (for example EH40 in the UK
and OSHA in the USA). In this mode of operation STEL‟s and TWA‟s are continually
calculated and compared to levels set in the instruments gas table. You can not
adjust settings or parameters of the instrument while in Health & Safety mode as
these could effect the ongoing calculations. Should you want to proceed with an
adjustment a WARNING screen will appear. You have the option to continue with
the adjustment by pressing Enter or abort and continue monitoring by pressing the
ESC key. Continuing with the adjustment will reset the instrument, calculations will
begin again from 0 once back in Health & Safety mode.

PC Requirements
IonPC Software must be used in conjunction with a PC/laptop using Windows XP. An IRDA port is required
for communication with the instrument. Many laptops are supplied with this facility. Alternatively IRDA
modules can be purchased from most computer retailers for use with your instrument. Before connecting
your PhoCheck+ to a PC for the first time, confirm that the PC‟s IRDA works correctly with another devise.
Installation of IonPC Software
1. Insert Ion Science software CD into your CD rom drive
2. The CD will automatically start up
3. Click on the Download Software button
4. The IonPC setup wizard will start.
7. Follow the instructions on screen.
8. The installer will automatically create a folder in your C drive to save IonPC into if you do not want
to save it there Browse for the location you would like it to be saved in and click Next
9. Select Next again and on to install the software
10. The software will take a few seconds to install then click Finished
11. You will now be able to open your IonPC software from the Icon on your desk top or from your Start
Menu/Programs/IonPC
Connecting PhoCheck+ with a PC
Switch on your PhoCheck+ instrument, enter the function menu and select the Data Transfer symbol by pressing
the enter key. When communicating with a computer the PhoCheck+ displays a '' within the data transfer
symbol. When not communicating an X will appear.
Place the PhoCheck+ on its side with the instruments infrared window a few
inches from the PC IRDA, then start the IonPC software.
Starting IonPC Software
Start the IonPC software either from your desktop via the shortcut or from the Start menu/Programs/Ion PC.
The instrument has 8Mb of memory, which is divided into 1Mb segments. When a segment becomes full,
data is then stored in the next segment.
Each time the user starts data logging, a new file is created. So, for example, six data logging sessions will
create six data files.
When a data logging session records data which spans across two or more 1Mb segments, a corresponding
number of files will be created and stored within the instrument and will apply to that particular data logging
session only. So, for example, two 1Mb segments spanned will result in two files created.
When the data is to be downloaded via the IonPC software, any files that have spanned two or more 1Mb
segments (i.e. two or more files) will be recognised and downloaded as a single file.

Maintenance
Blowing out the PID Cell will fix 99% of maintenance problems
When using the PID instrument in conditions of high ambient humidity, the
PID may show unexpected readings appearing to increase. This occurs due
to dust or other small particles within the detector becoming hydrated with
humidity. This causes these particles to conduct a signal between the
electrodes. This issue can be resolved by the user in the field using the
following procedure and a can of computer duster air.
First remove the lamp, following the instructions on lamp removal from the
cleaning the lamp section below (steps 1 – 6). Using a can of computer
duster, spray air down the small metal tube. Replace the lamp and cap and
test the instrument.
1. Keep the PID detector lamp window clean.
2. Replace the sample filters on a regular basis.
Frequency of cleaning the detector lamp and replacement of the filter depends
on the type of gas being detected and the quality of the background air.
3. Secondary Probe Filter
Designed to strengthen the instrument response, even in condensing
environments.
If the instrument background reading is high, change the main probe filter
first. If the readings remain high it will be necessary to change the secondary
probe filter as follows;
a) Using an 11mm (7/16”) spanner unscrew the probe fitting from the end
of the PID detector nozzle.
b) Remove and discard the secondary probe filter.
c) Insert a new secondary probe filter into the probe fitting.
d) Screw the probe fitting back onto the nozzle and tighten using the
11mm (7/16”) spanner.
CAUTION: DO NOT OVERTIGHTEN THE PROBE FITTING
Cleaning the PhoCheck+ Lamp
The PhoCheck+ PID relies on an ultraviolet light source ionising VOC gases as they pass across the lamp
window. This process may result in a very fine layer of contamination appearing on the detector window that
must be removed on a regular basis.
CAUTION!
The PhoCheck+ is a sensitive detector. Internal components must be
handled with clean hands and clean tools. The PhoCheck+ lamp is fragile.
Handle with great care!
1. Ensure that the PhoCheck+ is switched OFF.
2. Remove the probe and filter. Unscrew the black knurled ring to
expose the detector lamp.
3. Push a lamp-removing sleeve over the end of the lamp. This
allows the user to grip the glass.

Cleaning the PhoCheck+ Lamp (continued)
4. Extract the lamp from its socket by pulling it in a straight line away from
The PID cell. Force is only required when pulling the lamp past the O
ring. Once past the O ring the lamp will move freely.
5. Inspection of the lamp may reveal a layer of contamination on the
detection window that presents itself as a 'blue hue.' To check for
contamination, hold the lamp in front of a light source and look across
the window surface.
6. Inspection of the lamp may reveal a layer of contamination on the
detection window that presents itself as a „blue hue.‟ To check for

Protective / Decontamination Cover
Description
This unique accessory enhances the base intrinsically safe approval of Ion Science instruments, including
FirstCheck and PhoCheck, from category 2 (Zone 1) to category 1 (Zone 0) classification. The cover also
increases instrument's ingress protection rating to IP66 allowing the instruments to be used in applications
where the instruments are likely to get wet such as arson investigation, emergency response and in heavy
rainfall.
The cover being very low in cost has the advantage when used in HazMat applications, including possible
WMD exposure, in that it is simply removed after use and replaced with a fresh one keeping both the user
and instrument safe from exposure long after the event.
NB: the IS protective cover must be used only once. If it becomes torn or damaged the intrinsically safe
certification and ingress protection ratings revert to that of the instrument inside it.

Technical Specifications
Expected lifetime of parts
Batteries
On the condition of normal use battery capacity will be reduced to approximately 70% after 250 full
battery cycles or 1 year (whichever comes first).
New fully charged (rechargeable) batteries at 20 C > 10 hours normal use.
Affects on battery capacity:
10% less per 10 C drop in temperature.
As the batteries age they may self discharge to half capacity from fully charged state.
At 25 C – 50 days
37 C – 25 days
48 C – 5 days
60 C – 1 day
The back light will consume an additional 50% power and significantly reduce the instrument „on
time‟.
Filter
The filter should be changed every 100 hours of use. This frequency should be increased for dusty or
moisture laden environments.
PID Lamps
10.6 eV and 8.4 eV expected life of 3 years and 11.7 eV 1 month. Lamps are very fragile; please
handle with care at all times, never touch the window and do not drop! Lamp cleaning for normal use
is every 100 hours of use (based on 30 ppm for 100 hours). Reduce this if used in heavily gas
contaminated environments. Please note that some esters, amines and halogenated compounds may
accelerate window fouling; cleaning may be required for every 20 hours of use. Cleaning frequency
will also depend upon alarm levels set and prevailing environmental conditions.
PID Cell
Electronic cell has an indefinite life however it may suffer contamination problems – it is essential that
a clean filter is attached during use. Some gases such as methylene chloride in high concentrations
may condense onto the walls of the cell. In these cases the instrument should be returned to an
Authorised Service Centre for thorough cleaning.
NB: PID specifications relate to an isobutylene 100 ppm in air calibration at 20 C and 90% RH.
