1.1 Meaning of Symbols and Markings
Caution - refer to instructions
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 must only be used by a skilled and competent person
who is familiar with the relevant regulations, the safety risks
12
involved and the consequent normal safe working practices, and
under the conditions and for the purposes for which it has been
constructed and specified.
Objects may be much hotter than indicated due to factors such as
emissivity.
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. OPERATION
3.1 Low Battery Indication
If the symbol is displayed, the battery needs replacing as
measurement accuracy can no longer be guaranteed (See section
4.1 Battery Replacement).

3.3 Power On/Off
Press the button to turn on the IRC325.
The screen will display MARTINDALE ELECTRIC for approx. 10
seconds as the unit warms up.
To turn off, press for >2 seconds. The screen will briefly display
POWER OFF.
3.4 Auto Power Off
The IRC325 will automatically power off after 5 mins if not in use.
3.5 Measurement and Scanning
To scan an object or surface press and hold the IRC325 trigger.
HOLD will no longer be displayed.
Move the IRC325 until the screen crosshair is aligned with the area
of interest.
The temperature at the crosshair centre will be displayed.
Releasing the trigger will hold the image and the displayed
temperature.
3.6 Measurement Considerations
The IRC325 has a fixed surface emissivity setting of 0.95. This
must be considered when measuring temperatures of surfaces
with surface emissivity values other than 0.95. See section 3.7
for typical surface emissivity values of various materials.
The distance/spot ratio of the IRC325 is 15:1. At a distance of
15 feet for example, the spot diameter would be 1 foot. This
must be considered when making temperature measurements
6
because the measured temperature is the average temperature
within the area of the spot circumference. Therefore, for accurate
temperature measurement the spot circumference must be within
the target area. See figure 1.
Figure 1
Target
CORRECT Spot area INCORRECT
circumference
Allow time before use for temperature stabilisation if the IRC325
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.
3.7 Emissivity Values
The emissivity of the surface of a material is its effectiveness in
emitting energy as thermal radiation. Quantitatively, emissivity is the

7
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.

4. MAINTENANCE
4.1 Battery Replacement
The battery compartment is in the handle
of the unit.
Remove the battery cover screw and the
battery cover.
Replace with 3 new 1.5V, AA alkaline
batteries (IEC LR6, NEDA 15A), observing
correct polarity.
Replace the battery cover and screw.
Note: Do not mix old and new batteries.
4.2 Calibration
To maintain the integrity of measurements
made using your instrument, Martindale Electric recommends
that it is returned at least once a year to an approved Calibration
Laboratory for recalibration and certification.
Martindale Electric is pleased to offer you this service. Please
contact our Service Department for details.

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.

5. WARRANTY AND LIMITATION OF LIABILITY
This Martindale product is warranted to be free from defects in
material and workmanship under normal use and service. The
warranty period is 2 years and begins on the date of receipt by the
end user. This warranty extends only to the original buyer or end-
user customer, and does not apply to fuses, disposable batteries,
test leads or to any product which, in Martindale’s opinion, has been
misused, altered, neglected, contaminated, or damaged by accident or
abnormal conditions of operation, handling or storage.
Martindale authorised resellers shall extend this warranty on new and
unused products to end-user customers only but have no authority to
extend a greater or different warranty on behalf of Martindale.
Martindale’s warranty obligation is limited, at Martindale’s option, to
refund of the purchase price, free of charge repair, or replacement of
a defective product which is returned to Martindale within the warranty
period.
This warranty is the buyer’s sole and exclusive remedy and is in lieu
of all other warranties, expressed or implied, including but not limited
to any implied warranty of merchantability or fitness for a particular
purpose. Martindale shall not be liable for any special, indirect,
incidental or consequential damages or losses, including loss of data,
arising from any cause or theory.
Since some jurisdictions do not allow limitation of the term of
an implied warranty, or exclusion or limitation of incidental or
consequential damages, the limitations and exclusions of this warranty
may not apply to every buyer. If any part of any provision of this
warranty is held invalid or unenforceable by a court or other decision-
maker of competent jurisdiction, such holding will not affect the validity
or enforceability of any other provision or other part of that provision.
Nothing in this statement reduces your statutory rights.
