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). Also available is the option to upgrade to the FirstCheck+ multigas range of instruments upon
return of your instrument to Ion Science. Please see page 48 for more details relatingto upgrade options.
PhoCheck+ has two principle modes of operation, Health & Safety and Survey mode.
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.
Survey is the default mode of operation whenever the Health & Safety mode is NOT selected. This mode is
often used in applications 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.
For more information on these modes of operation please see page 25.
PhoCheck+ versions 2000, 3000 and 5000 automatically data log the instruments readings every second.
These readings are stored in the instrument's memory with a date and time stamp. For more i nformation
please see page 17.

* Please note that the Cal adaptor is to be used in conjunction with a PhoCheck+ Calibration Kit accessory
(part number A-845213). WARNING: when fitting the Cal adaptor onto the gas tube (part of the
Calibration kit) ensure that the small breather hole of the Cal adaptor is not covered as this will cause the
instruments internal pump to be damaged beyond repair. Your warranty will be invalidated if the pump is
damaged in this way.
Removing the PhoCheck+ from its case
Carefully remove the PhoCheck+ instrument from its case being careful not to damage the filter and pr obe
assembly. 'Luer' type connectors are used to connect the PhoCheck+, filter and probe together and require a
quarter-turn ONLY to connect / disconnect them. Do not over tighten.
To avoid drawing dust or particulate matter into the detector cell we suggest always fitting the filter with the
Ion Science logo facing away from the instrument, therefore dust only collects on the same one side of the
filter and is not inadvertently drawn into the instrument if the filter is attached the other way round.

Getting started
1. Turn the instrument on by pressing the key.
2. Press and hold the key and check the correct gas, alarm levels and zero mode are selected.
3. The screen will flash for 1 minute while the detector warms up–check for a reading on the display
Between 0.2ppm and 2ppm.
4. Replace the probe and filter with the blue carbon filter–check for a reading from 0.0 to 0.2ppm.
5. Remove the carbon filter and replace the probe and filter.
6. If the results are not as expected, perform a custom calibration first ensuring the correct gas is
selected.
Setting alarm levels
We recommend that alarm levels are setto user specifications as soon as possible before being used for the
first time. Please see page 19 for details of how to set alarm levels.
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 23 for details on how to set the date and time.
Selecting a gas from the inte rnal 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 pages 23 & 24.
Rechargeable Batteries
Although PhoCheck+ instruments leave the factory fully charged, 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 38.
Alkaline Batteries
Fit the battery pack supplied with the PhoCheck+. For more information please see the battery section of
this manual page 38.

Function Menu
Once selected use the ‘UP’and ‘DOWN’keys to highlight the function you require and press ‘ENTER’to
select. Many features can be adjusted in this section including gas selection, zone maintenance, data transfer
and alarm levels. Details of these and other functions are to be found on the following pages.
The instrument has 8Mb of memory, which is divided into1Mb 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 twofiles 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.

Instrument Menu _____
General
In the function menu use the ‘Up’and ‘Down’keys to find the function you require. To enter the function,
press the ‘Enter’key.
Data Logging, Zones & Files
PhoCheck+ versions 2000, 3000 and 5000 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 over write previous readi ngs. An alarm can be set (see page 25) to inform the user
that this is due to happen giving time to download any data that may be over written.
Data logged measurements are stored in files created automatically and issued a number that is
incremented each time a new file is opened. 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 PhoC heck+ 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 whic h
the user can name themselves, either direct via the instrument or by using the IonPC software.
________________________________________________________________
