1. SAFETY INFORMATION
REMEMBER: SAFETY IS NO ACCIDENT
These instructions contain both information and cautions that
are necessary for the correct operation and maintenance of this
product. It is recommended that you read the instructions carefully
and ensure that the contents are fully understood.
Particular attention should be paid to the Precautions and Technical
Specifications.
Please keep these instructions for future reference. Updated
instructions and product information are available at: www.
martindale-electric.co.uk
1.1 Meaning of Symbols and Markings
Caution - refer to instructions
Caution - Laser radiation
Class 2 Laser Class 2 lasers are limited to a maximum output
power of 1 milliwatt or one-thousandth of a watt
(abbreviated to mW) and the beam must have a
wavelength between 400 and 700 nm. A person
receiving an eye exposure from a Class 2 laser
beam, either accidentally or as a result of someone
else’s deliberate action (misuse) will be protected
from injury by their own natural aversion response.
This is a natural involuntary response which causes
the individual to blink and avert their head thereby
terminating the eye exposure. Repeated, deliberate

2
exposure to the laser beam may not be safe. Some
laser pointers and barcode scanners are Class 2
laser products.
Equipment complies with relevant EU Directives
End of life disposal of this equipment should be in
accordance with relevant EU Directives.
1.2 Precautions
This product has been designed with your safety in mind, but please
pay attention to the following warnings and cautions before use.
Warnings
The IRC325 and IRC327 must only be used by a skilled and
competent person who is familiar with the relevant regulations,
the safety risks involved and the consequent normal safe working
practices, and under the conditions and for the purposes for which it
has been constructed and specified.
Do not use if damaged.
Never look or stare into the laser beam as permanent eye damage
could result.
Never direct the laser beam at any person’s (or animal’s) eyes as
eye damage could result.
Reflections of the laser beam from mirrors or other shiny surfaces
can be as hazardous as direct eye exposure.
Objects may be much hotter than indicated due to factors such as
emissivity.
3
Cautions
Avoid severe mechanical shock or vibration and extreme
temperature.
To avoid possible corrosion from leaking batteries, remove the
batteries if discharged, or when the unit is not in use for an
extended period.

3.7 Measurement, Scanning and Saving Images
Power ON the IRC327 and referring to sections 3.6 and 3.8 set up
the IRC327 functions as required.
Point the IRC327 at the object of interest and press the trigger to
activate the LASER/FLASH/UV source if enabled.
Move the IRC327 until the screen centre/screen crosshair/laser
crosshair is aligned with the area of interest.
The temperature at the screen centre/screen crosshair/laser
crosshair centre will be displayed.
Releasing the trigger will hold the image and the displayed
temperature.
To save the displayed image to the micro-SD card toggle RIGHT,
to discard toggle LEFT.
The screen will automatically revert to scan mode after 4 seconds.
3.8 Measurement Considerations
The surface emissivity setting of the target surface must be
taken into account when measuring temperature. See section
3.8 for typical surface emissivity values of various materials.
Set the correct emissivity value as described in section 3.6.
The distance to spot ratio of the IRC327 is 30:1. At a distance
of 30 feet the spot diameter would be 1 foot and is represented
by the outer circle of the laser crosshair. The measured
temperature is the average temperature within the area of the
outer circle of the laser crosshair. For accurate temperature
measurement the laser crosshair outer circle must be within the
target area. See figure 1. 10
Figure 1

Allow time before use for temperature stabilisation if the IRC327
is moved between locations with differing ambient temperatures,
e.g. one location at 23ºC and another at 0ºC. Up to 30 minutes
may be required for extreme temperature changes.
Reflected background temperature can effect temperature
measurement. Very hot objects or very cold objects in the
vicinity of the target or object of interest can affect the apparent
temperature and measurement accuracy, especially when
surface emissivity is low.
3.9 Emissivity Values
The emissivity of the surface of a material is its effectiveness in
emitting energy as thermal radiation. Quantitatively, emissivity is the
ratio of the thermal radiation from a surface to the radiation from an
ideal black body surface at the same temperature as given by the
Stefan–Boltzmann law.
Refer to table 1 for the nominal surface emissivity values for various
materials.

3.10 Transferring Saved Images to a PC or Laptop
The images saved to the SD card can be transferred to a PC or
laptop in one of two ways:
By removing the SD card and
connecting it to the PC or laptop
using a suitable adaptor;
By connecting the IRC327 directly to
a PC or laptop using a micro-USB to
USB cable (preferred method).
The SD card and micro-USB port
can be accessed by removing the rubber cover with the laser
warning from around the tripod mounting point. 12
To remove the SD card press it in against the spring pressure and
it will pop out.
A micro-SD card of 2 GB is supplied, but a card up to 32 GB may
be used.
If connecting to a PC or laptop with a USB cable the IRC327 must
be switched OFF.
The IRC327 will be recognised as a USB device and the images
can be transferred, erased, etc. in the normal way.
The images are saved in bitmap (.BMP) format and include the
measured temperature reading and emissivity setting information.
3.11 UV Leak Detection
The IRC327 can be used for leak detection in cooling systems, air
conditioning systems, etc. by using a suitable UV indicator dye.
To enable the UV function, see sections 3.5 and 3.6.

4.3 Cleaning
If contamination is found, clean with a damp soft cloth and if
necessary a mild detergent or alcohol. If required use a cotton
bud to clean the lens. Do not use abrasives, abrasive solvents, or
detergents which can cause damage to the unit. If a mild detergent
is used, the unit should subsequently be thoroughly cleaned with a
water dampened soft cloth. After cleaning, dry and allow to remain
in a dry environment for 2 hours before use. 15
4.4 Repair & Service
There are no user serviceable parts in this unit other than those
that may be described in section 4. Return to Martindale Electric if
faulty. Our service department will quote promptly to repair any fault
that occurs outside the guarantee period.
Before the unit is returned, please ensure that you have checked
the unit and batteries.
4.5 Storage Conditions
The instrument should be kept in warm dry conditions away from
direct sources of heat or sunlight, and in such a manner as to
