gloves away from moving parts.
Do not overreach. Keep proper footing and balance at all times to enable better
control of the device during unexpected situations.
Use safety equipment. Always wear eye protection. Non-skid safety shoes, hard hat,
or hearing protection must be used for appropriate conditions.
Do not repair or adjust energized equipment alone, under any
circumstances. Someone capable of providing first aid must always be
present for your safety.
To work on or near high voltage, you should be familiar with approved
industrial first aid methods.
Always obtain first aid or medical attention immediately after an injury.
Never neglect an injury, no matter how slight it seems.

Use only accessories that are recommended by the manufacturer.
Do not attempt to open the device.

Introduction to the CMAC 4230 Wireless Infrared Thermometer
Safety Instructions
1 - 2 Wireless Infrared Thermometer CMAC 4230
User Manual
Device service must be performed only by qualified SKF repair personnel.
Use only accessories recommended or provided by SKF Reliability Systems.
Energized equipment
Never work on energized equipment unless authorized by a responsible authority.
Energized electrical equipment is dangerous. Electrical shock from energized
equipment can cause death. If you must perform authorized emergency work on
energized equipment, be sure that you comply strictly with approved safety
regulations.
Hazardous Locations
The device must not be opened inside the hazardous area.
The batteries must be changed only outside the hazardous area.
Additional batteries must not be carried in the hazardous area.
Only the approved battery types must be used.
In potentially explosive areas, the device must be operated only when in its leather
pouch. Please ensure that the leather pouch is always closed completely and is
undamaged while using.
Only the accessories approved by the manufacturer must be used.
Avoid using the device in corrosive acidic or alkaline mediums.
The supplied thermocouple must be used only outside the hazardous area.
Avoid Submerging in Water
This equipment has been designed to be splash and dust resistant. However, avoid
direct contact with water, wet surfaces, or condensing humidity. If the instrument is
subjected to these conditions, adverse operation may result, and there is a risk
serious injury or damage should electrical shock or fire occur. Allow the instrument
to dry thoroughly before operation. Avoid opening the card slot door in locations
where contact with water or other contaminants may occur.
Avoid Damage
To avoid costly damage to the instrument or injury from a falling instrument, place
the instrument on a solid stable surface when not in use and do not place any heavy
objects on it.
Use a damp, clean cloth for cleaning. Do not use cleaning fluids, abrasives, or
aerosols. They could cause damage, fire, or electrical shock.
Avoid Battery Compartment Exposure
Do not open the battery compartment in a hazardous area, or in locations where
contact with water or other contaminants may occur.

Functional description and operating instructions
Please take the time to read through this operating manual carefully
to ensure that you are familiar with all the functions of your CMAC
4230.
Operation
All objects with a temperature above absolute zero radiate infrared energy that
spreads in all directions at the speed of light. If an infrared thermometer is aimed at
a measurement object, the lens gathers the energy and focuses it on an infrared
sensor. The sensor reacts by generating a voltage signal that is directly proportional
to the absorbed energy. The microprocessor-controlled electronic unit of the device
can determine and display the current temperature using additional parameters.
Measurement objects with a shiny or polished surface not only radiate energy, but
also reflect a part of the radiation from their surroundings.
An emissivity factor between 0.1 and 1.5 takes account of this fact so that only the
actually radiated (and not the reflected) energy is included in the calculation of the
measured value. The majority of applications are measured with an emissivity of
0.95. The CMAC 4230 is therefore preset to 0.95 and can be adjusted in steps of
0.01 depending on the application. Emissivity range over 1.00 is intended for
applications, where adjacent measurement objects having different temperatures are
to be measured. For example, this is the case if there are two conveying lines with
different temperatures and the temperature of the colder one is to be measured.
The radiated reflected energy would thereby falsify the measurement and hence a
correct result would be impossible. The temperature can now also be measured
accurately using the emissivity setting > 1.00 by way of a one-time reference
measurement using a contact thermometer.
Measuring marking
Keep in mind that the measured part of the object surface (3 point measuring spot
marking) changes with the increasing measuring distance as shown in the figure.
19 mm @ 1150 mm
Focus point E:M = 60:1 Distant field E:M= 35:1
The ratio between the measuring distance and measuring spot diameter is
approximately 60: 1 at distance (e) between the sensor and the measurement object

Functional description and operating instructions
Measurement

User Manual
(mm) the focus point and approximately 35:1 in the distant field (> 10 m). To take
continuous readings, set the LOCK switch in the battery compartment to On and
press the measurement button (the laser does not remain on continuously). Reset
the LOCK switch to Off for the normal operation. The laser sight makes sighting a
measurement object easier. Laser points indicate the exact diameter of the
measuring spot. Use the LASER function key for switching the laser on and off by
keeping the measurement button pressed. The laser icon (refer to 8.5 Display
screen) indicates the switched-on laser.
Measurement
Aim at the object to be measured and press the measurement button. The
measured temperature appears in the display. It is visible in the display for seven
seconds after releasing the measurement button. If another button is not pressed,
the device switches off automatically after this time. Selected functions remain set
and the function selection menu returns to the initial position. To recall the last
measured value, press ENTER without pressing the measurement button.

How to Establish a Connection with the Data Manager
(Microlog Inspector only) On the Microlog Inspector, the WIRG Connection icon ( )
displays at the bottom of the screen during temperature data collection if the
Microlog Inspector is connected with the WIRG.
(MARLIN only) On the MARLIN, the Wireless Connection icon ( ) at the bottom of
the screen displays the data manager’s connection status with the WIRG, and allows
access to the WIRG Setup screen. The icon appears blue when the data manager
detects and establishes communication with the WIRG, and gray when the wireless
connection is disabled, or when the data manager does not detect the WIRG.
To set up the WIRG for communication:
Power on the WIRG and enable its Bluetooth setting.
Power on your Microlog Inspector / MARLIN.
(Microlog Inspector only) On the Settings display, select the Temperature Gun
icon to display the Temperature Gun Setup screen.
