Responsibility for Use
PhoCheck+ instruments detect a large range of gases, w hich are potentially dangerous from both a
poisoning and/or an explosive perspective. PhoCheck+ instruments have many adjustable and selectable
features allowing the detector to be used in a variety of ways.
Ion Science Ltd can accept no responsibility for the incorrect adjustment of features that cause harm or
damage to persons or property.
PhoCheck+ can be used as a personal safety device. It is the user’s responsibility to respond appropriately t o
an alarm situation.
! WARNINGS!
1. For reasons of Intrinsic Safety, batteries MUST NOT be charged or replaced within potentially
flammable areas. Ensure you are in a SAFE area before carrying out any type of maintenance on
the PhoCheck+ instrument.
2. Substitution of components may impair intrinsic safety and resultin unsafe conditions.
3. For safety reasons, the PhoCheck+ must only be operated and serviced by qualified personnel.
4. Please read and understand this User Manual fully before operating or servicing the PhoCheck+.
! CAUTION!
It is essential that the PhoCheck+ is always used with a supplied PTFE 0.5 micron filter fitted to the front of
the instrument. The PhoCheck+ internal pump draws over 200 ml/min of air into the instrument and without
a filter; particles of debris and dust will be drawn into the cell inhib iting the correct function of the
instrument. These filters are consumable and should be changed every 100 hours of use. The frequency of
replacement should be increased for dusty or moisture laden environments. Filters are available for purchase
from Ion Science; see our accessories page (pg 46) for more information.

Statements _____
Quality Assurance
PhoCheck+ has been manufactured i n compliance with ISO9001:2000, which ensures that t he equipment
supplied to our customers has been designed and assembled reproducibly, from traceable components, and
leaves Ion Science calibrated to stated standards.
Disposal
Dispose of PhoCheck+, its components and any used batteries in accordance with all local and national
safety and environmental requirements. This includes the European WEEE (Waste Electrical and Electronic
Equipment) directive. Ion Science Ltd offers a take back service. Please contact us for more information.
The PhoCheck+ field case material is recyclable polypropylene.
Calibration Facility
Ion Science Ltd offers a calibration service including the issue of certification confirming calibration with
equipment traceable to UK national standards.
A PhoCheck+ Calibration Kit is available from Ion Science to allow a two-point calibration to be carried out in
the field as a custom calibration. However Ion Science does recommend the annual return of all instruments
for a yearly service and calibration.

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.

Packing List
Please take a little time to check the contents in the PhoCheck+ case.
Item Description Qty.
1. PhoCheck+ instrument 1
2. PID lamp (fitted) 1
3. Probe - 100mm (fitted) 1
4. PTFE filter - 50 micron (fitted) 1
5. Battery charger (if rechargeable type) 1
6. Battery clip (if non-rechargeable) 1
7. Screw driver (if non-rechargeable) 1
8. Manual 1
9. IonPC software CD 1
10. IS Protective Cover 1
11. Cal Kit Sample containing:
·PID lamp cleaning Kit (Includes alumina
powder and 2 applicators for 1 clean) 1
·Carbon canister 1
·PTFE filter –50 micron 1
·Cal adaptor* 1
· Lamp removal tools (neoprene sleeves) 2
* 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.
