WARNING!
After measurement of high temperature, the probe
may be hot for a while.
Additional Features
Changing Scales
To change scales between degrees Fahrenheit
and degrees Celsius, press the button on the panel,
(marked °F / °C), while the display is active. Even if the
trigger is released and the display is in its 60-second
automatic hold, you can convert the reading between
scales. Each time you press the scale button, the
60-second hold will reset. The INF195C will default to
the scale last used the next time it is turned on.
Using the Laser Sight
The INF195C is classified as a “Laser Product”, and is
regulated by the FDA.
CAUTION!
Using controls, making adjustments, or performing
procedures in any manner other than that specified
herein may result in hazardous radiation exposure.
LCD Error Messages
The thermometer incorporates visual diagnostic
messages as follows:
: “
Hi
” or “
Lo
” is displayed when the
temperature being measured is
outside the settings of HAL and LAL.
: “
Er2
” is displayed when the
thermometer is exposed to rapid
changes in the ambient temperature.
: “
Er3
” is displayed when the ambient
temperature exceeds the operation
range of 32˚ to 122˚F (0˚ to 50˚C). The
thermometer should be allowed
plenty of time (minimum 30 minutes)
to stabilize to the working/room
temperature.
: For all other error messages it is
necessary to reset the thermometer.
To reset the thermometer, turn the instrument off, remove
the battery and wait for a minimum of one minute.
Reinsert the battery and turn it on. If the error message
remains please contact UEi service department for further
assistance.
Battery Indicators
The thermometer incorporates visual low battery
indications.
: “Battery OK” measurements
are possible
: “Battery Low” battery needs to be
replaced, measurements are
still possible
: “Battery Exhausted” measurements
are not possible
Maintenance
Periodic Service
WARNING!
Repair and service of this instrument is to be performed
by qualified personnel only. Improper repair or service
could result in physical degradation of the instrument.
This could alter the protection from electrical shock and
personal injury this instrument provides to the operator.
Cleaning
Periodically clean your instrument’s case using a damp
cloth. DO NOT use abrasive, flammable liquids, cleaning
solvents, or strong detergents as they may damage the
finish, impair safety, or affect the reliability of the struc-
tural components.
Battery Replacement
Always use a fresh replacement battery of the specified
size and type. Immediately remove the old or weak bat-
tery from the meter and dispose of it in accordance with
your local disposal regulations. Old or defective batteries
can leak chemicals that corrode electronic circuits.
To replace the battery:
1. Slide the battery cover straight down then away
from the INF195C.
2. Replace with fresh “AAA” (2x) batteries.
3. Replace cover.
Lens Care
The sensor lens is the most delicate part of the ther-
mometer. The lens should be kept clean at all times. Care
should be taken when cleaning the lens using only a
soft cloth or cotton swab with water or medical alcohol.
Allowing the lens to fully dry before using the thermom-
eter. Do not submerge any part of the thermometer in
liquids.
WARNING!
Under NO circumstance should you expose batteries
to extreme heat or fire as they may explode and cause
injury.
NOTE:
This instrument contains no user serviceable
parts. If service becomes necessary, call UEi and ask for
the service department. See the warranty section of this
manual for additional details.

Infrared Thermometer
Specifications
EMC/RFI
Readings may be affected if the unit is operated within
radio frequency electromagnetic field strength of
approximately 3 volts per meter, but the performance
of the instrument will not be permanently affected.
IR Thermometers
Infrared Thermometers measure the amount of thermal
radiation emitted from an objects surface. To take a
measurement, the object must be within the field of
view of the infrared thermometer, or the reading may
include objects surrounding your target. This target size
is determined in the distance to spot ratio stated on the
instrument specifications. At a ratio of 9:1, a distance
from your target of nine feet will give you a circle with
one foot diameter. At 20:1 ratio gives the same one foot
target now at 20 feet, so you can see that higher is
better, but typically more expensive due to the cost of
the optics involved.
The other common question is regarding emissivity. In
simple terms emissivity is a percentage of energy
emitted from a surface compared to the energy emitted
from a black body source. If a surface emits one half
(1/2 or 0.5) the amount of energy at a given temperature
and wavelength as a black body, it is said to have an
emissivity of 0.5.
Surfaces closest to the black body level would be flat
black, and those farthest from it would be mirror or
chrome surfaces. With a set emissivity level some
surfaces may measure lower than actual, because their
surface is emitting less thermal radiation at a given
temperature. Although you may have a fixed emissivity
of 0.95, most items measured will provide a reasonably
accurate result. Having a fully adjustable emissivity will
give you the ability to fine tune your instrument to a
specific application.
To determine the emissivity of the surface being tested,
paint a portion with flat black paint, and then measure
the temperature of the painted area and compare it
to the temperature of the standard surface. Use the
following to determine the emissivity to use.
Temperature (Standard area) divided by temperature
(painted area). As an example 61° in the standard area
and 68° painted is 61/68 or 0.89
