OPERATOR’S MANUAL
Description
The SIG1 thermometer is a low cost, standalone
non-contact infrared thermometer. Simply aim the
thermometer at the target and pull the “trigger” to
display the surface temperature. The temperature
measured will be the average of all the tempera-
tures in the field of view. The closer you are to the
target, the smaller the area. The further away, the
larger the area measured.
Applications
The infrared temperature measurement is fast
and easy. It works best for fast readings, relative
readings (one to another or the same one at differ-
ent times), or temperature readings of hard to reach
places. The following are some applications:
• “Shoot” an inside wall for quick and fast indoor
ambient temperature reading.
• Heating and air conditioning where fast and/or
easy measurement is most important.
• Motor bearings: high temperature can indicate
bearings that might need replacement.
• Circuit breakers: a circuit breaker that is not
operating properly can get hot. By scanning a
panel, you will be able to find the hot one.
• Poor power line connections: a bad connection
can get hot.
IR Temperature Measurement
Objects dissipate heat in the form of infrared (IR)
energy. The hotter it is, the more infrared energy. If
there's enough radiation, you can feel it. The SIG1
infrared thermometer collects infrared energy from
a circular viewing area and measures the total
amount of energy collected. The SIG1 converts the
total energy measured to a temperature. The further
you go from the target, the larger the sampling
space.
If you want to get the temperature of something
small, such as a pipe, you must get close enough
for the pipe to take up the whole viewing area circle.
Otherwise the pipe and the background tempera-
tures will be averaged into the reading.
The accuracy of many infrared temperature
measuring systems is adversely affected by ambi-
ent temperature.
You need to be aware that if the target surface is
reflective enough, it may reflect infrared from other
objects. For example, if you take a reading of a
shiny metal surface, the infrared energy of your face
may reflect enough energy off the surface to affect
the reading. For this reason, it’s a good idea to put
non-reflective tape or paint on reflective surfaces
when taking IR temperature readings.
"Emissivity" of the target surface also affects the
temperature reading. For a given temperature, the
higher the emissivity, the higher the reading. The
lower the emissivity, the lower the reading.
Emissivity of a surface indicates how easy it is for
the infrared to get out. Emissivity for a dull, black
surface is high (nearly 100%) so it's easy for the
infrared to get out. Emissivity for a shiny surface
can be much lower. If the emissivity is low, the
measured temperature will be lower than actual.
For relative readings of the same kind of surface,
this isn't a problem. For some applications, it may
be necessary to spray dull, black paint on the target
to insure a more accurate reading.
For best accuracy use contact sensors (thermo-
couples, thermistors, etc.) anytime you take a tem-
perature measurement. Infrared instruments should
only be used when you aren’t able to touch the sur-
face to be measured.
WARNING
Never point the device towards the eyes
permanent eye damage may occur.
Use extreme caution when using the laser.
Keep out of the reach of children.
Be careful around mirror surfaces since
mirrors can reflect the laser. Looking into the
reflected laser is just as damaging as looking
directly at the laser.

Operation
1. Remove protective plastic cover.
2. Point SIG1 towards target to be measured.
3. Pull trigger to light the target with the laser and
measure its surface temperature.
4. As long as the trigger is held down, the SIG1
will constantly update the measurement and the
blue backlight will illuminate the display.
5. Once the trigger is released, the last measure-
ment will be shown and held until the trigger is
pressed again or until the SIG1 turns off.
Field of View
The SIG1 takes it’s measurement from a circle of
a size determined by a simple ratio of 10:1. The
diameter of this circle is 1/10 the distance between
the target and the tip of the SIG1. For example, if
you’re standing 20 feet from your target, the size of
the circle you’re taking the average temperature of
will be 2 feet wide.
Laser Sight
When the trigger is pulled the red laser dot will
shine about 1/4” above the center of the circular
area being measured by the thermometer. Be sure
to remove protective cap before taking measure-
ments.
°F or °C
To switch between °F and °C open the battery
cover and move the switch to the desired scale.
Battery Replacement
When the 'Low Battery' icon indicates the battery
is low, the battery should be replaced. The battery
is located under the cover at the rear of the SIG1.
The battery should be placed upside down (termi-
nals facing down) so that bunching of the wires is
avoided.
Note: When a new battery is installed, the meter
will power on to show it has recognized the new bat-
tery. Auto-off will occur after 10 seconds without
operation.
Cleaning
Since the laser aperture and lens are delicate,
keep protective plastic cover on the SIG1 when not
in use. When the case gets dirty, clean with a damp
cloth and mild detergent. Do not use abrasives or
solvents.
Warranty
The product is warranted to the original purchas-
er against defects in material or workmanship for a
period of one (1) year from the date of purchase.
During the warranty period, Fieldpiece Instruments
will, at its option, replace or repair the defective unit.
This warranty does not apply to defects resulting
from abuse, neglect, accident, unauthorized repair,
alteration, or unreasonable use of the instrument.
Any implied warranty arising out of the sale of
Fieldpiece's products including but not limited to
implied warranties of merchantability, and fitness for
purpose, are limited to the above. Fieldpiece shall
not be liable for incidental or consequential dam-
ages.
Service
Return any defective SIG1 to Fieldpiece for war-
ranty service along with proof of purchase. Contact
Fieldpiece for out of warranty repair charges.
