GTC LTX12 User manual

1. GENERAL SAFETY RULES
Read all instructions. Failure to follow all
instructions listed below may result in
hazardous radiation exposure, electric
shock, re, and/or serious injury.
• CAUTION—use of controls or adjustments or performance
of procedures other than those specied herein may result
in hazardous radiation exposure.
• DO NOT operate this instrument in areas where there is risk
of re or explosion, like in the presence of ammable liquids,
gases, dust, etc.
• DO NOT disassemble the instrument. There are no user
serviceable parts inside. Disassembling the instrument will
void all warranties on the product.
• DO NOT modify the instrument in any way. Modifying the
instrument may result in hazardous laser radiation exposure.
• To ensure that the instrument is used safely, follow all safety
and operating instructions in this manual. If the instrument
is not used as described in this operation manual, the safety
features of this device may be impaired.
• To avoid personal injuries and damage to the instrument, use
extreme caution when working around hot machine or engine parts,
such as radiators, exhaust manifolds, catalytic converters, etc.
• Repair and servicing must always be performed by qualied
repair personnel. Repairs performed by unqualied personnel
could result in serious injury.
• This instrument is designed for indoor use at temperatures
between 32°F and 122°F (0°C to 50°C), altitudes up to 6500
ft. (2,000 m), and 10% to 90% relative humidity.
2. LASER SAFETY RULES
This label is on your
laser instrument
for your safety.
ALWAYS BE AWARE
of its location when
using the tool.
DO NOT direct the laser beam at persons or
animals and do not stare into the laser beam
yourself. This tool produces class 2 laser
radiation and complies with 21 CFR 1040.10 and
1040.11 except for deviations pursuant to Laser
Notice No. 50, dated June 24, 2007. This can lead
to persons being blinded.
Working safely with this instrument is possible only when the
operating and safety information are read completely and the
instructions contained therein are strictly followed.
• Never make the warning labels on the instrument unrecognizable.
• Never aim the beam at a workpiece with a reective surface.
• Mirrors or similar reective surfaces are not recommended for laser
use, as these could reect the beam back towards the operator.
• Do not point the laser beam at persons or animals and do not look
into the laser beam yourself, not even from a long distance.
• Do not use laser viewing glasses as safety goggles, because they
do not protect against laser radiation.
• Do not allow children to use the measuring tool without supervision.
They could unintentionally blind other people.
• ALWAYS: Make sure that any bystanders in the vicinity of use are
made aware of the dangers of looking directly into the instrument.

4.3 Measurement Procedures
4.3.1 Temperature Measurement
•Hold the instrument by its handle, point the IR Sensor at the area
or object to measure, and press the Measurement Trigger.
•While the Measurement trigger is kept pressed, the instrument
will continuously measure and update the display with the
temperature of the object the IR sensor is pointed at.
•After the Measurement trigger is released the instrument will
hold the last temperature reading for 7 seconds, then shut off
automatically.
4.3.2 Field of view or measurement target area
•To ensure accurate temperature measurements, make sure that
the target object is larger than the unit spot size, at the measuring
distance.
•The smaller the target, the closer you should be.
•For maximum accuracy, make sure that the target area is at least
twice as large as the spot size.
4.3.3 Selecting Temperature Units (°C/°F).
•Make sure the instrument is turned on, if not press the
Measurement trigger.
•Pressing the °C/°F button will switch between degrees Celsius
and degrees Fahrenheit as the temperature measurement units.
•The temperature reading and selected measurement units will be
displayed on the LCD.
4.4 ThermoSounder
4.4.1 Introduction
The ThermoSounder is a feature of your LTX12 that facilitates
nding temperature variations or differentials (e.g. cold and
hot spots) quickly and easily by providing a sound that varies
proportionally to temperature differences.
4.4.2 Activating the ThermoSounder function
•Make sure the instrument is turned on, if not press the
Measurement trigger.
•Pressing the ThermoSounder button will turn this function on and off.
•The ThermoSounder indicator is displayed on the LCD when activated.
4.4.3 Using the ThermoSounder function
•Activate the ThermoSounder function as described in 4.4.2.
•Point at the area or object whose temperature you want to use as
reference and press the Measurement trigger.
•The LTX12 will use the reference temperature to generate a
‘reference’ beeping.
•Higher temperatures (than the reference) will be indicated by a
faster pace of beeping, the more the difference, the faster the
pace of the beeping (proportional to the temperature difference).
•Lower temperatures (than the reference) will be indicated by a
slower pace of beeping, the more the difference, the lower the
pace of beeping (proportional to the temperature difference).
•The reference temperature for the ThermoSounder will be
maintained as long the Measurement trigger is pressed.
•To choose a new reference temperature, release the Measurement
trigger, then point at the area or object with the new temperature
you want to use as reference and press the Measurement trigger.
4.5 Other Functions
4.5.1 Display Hold
•The instrument will automatically hold the last temperature
reading for approximately 7 seconds after the Measurement
trigger has been released.
4.5.2 Display Backlight
•Make sure the instrument is turned on, if it is not, press the
Measurement trigger.
•Pressing the Backlight on/off button, will turn the display backlight
on and off.
• When the backlight is not needed, turn it off to prolong battery life.
4.5.3 Laser Pointer
• To turn the laser sight on or off, press the Laser on/off button,
when the unit is on. The laser sight indicator will appear on the
display when the laser sight function is on.
5. MAINTENANCE
5.1 Battery Replacement
In order to avoid laser radiation exposure
when removing or replacing the battery
always make sure the laser aperture (located
opposite to the display) is pointing away from any person, animal,
or reective surface.
• When the battery is low and needs to be replaced, the “Low battery
indicator” symbol will appear on the lower left hand side of the display.
• To replace the battery, open the battery compartment cover
(located at the front of the handle) by pulling on the nger indents
near the trigger, and remove the battery.
• Replace with a new 9 V alkaline battery type NEDA 1604 or
IEC6F22 observing the proper polarity when connecting the battery
terminals, and close the battery cover.
5.2 Cleaning
In order to avoid laser radiation exposure,
remove the battery before performing any
cleaning of the lens or exterior of the instrument.
5.2.1 Lens Cleaning
Debris or dirt on the lens may cause obstruction and reduce the
accuracy of the thermometer. If this occurs, either wipe the lens
with a cotton swab (moistened with water only) or blow the loose
particles off with clean compressed air. Do not use solvents on the
lenses, as they may damage the instrument.
5.2.2 Exterior Cleaning
Periodically wipe the enclosure with a soft damp cloth and mild
household cleanser. Do not use abrasives or solvents. Ensure that
no water gets inside the instrument to prevent possible short circuits
and damage.
6. WARRANTY
One year limited warranty, excluding batteries and fuses. For
details see Standard Warranty Information on our web page or
