Thank you for purchasing the ennoLogic® High
Temperature Laser nfrared Thermometer eT1600S, a high-
quality instrument with many advanced features. The
thermometer accurately measures temperatures of surfaces
by sensing the emitted thermal radiation of the surface. t is
also capable of making contact temperature measurements
with the included Type K thermocouple. n this manual
you will find detailed operating instructions and
descriptions of each of the advanced features of the
ennoLogic infrared thermometer.

Battery
The unit is powered by a 9V battery (NEDA 1604A or EC
6LR61, or equivalent). The battery compartment is located
inside the handle, covered by a black lid that is hinged at
the base of the unit. To open the lid, find the two indents
adjacent to the trigger button and slide a fingernail behind
the lid at the indent to pull it open. Attach the 9V battery to
the wired clip and slide the battery into the battery
compartment. (Tuck the wire in next to the battery;
otherwise the lid may not close properly.)
How to Use Your IR Thermometer
Aim the R thermometer at the surface you want to
measure. Make sure there are no obstructions between the
unit and the target surface. Steam, dust, and smoke can
affect the measurement. Do not attempt to measure
through glass. Thermal shock can cause inaccurate
readings as well, make sure to let the unit warm up to
room temperature before using it. Press the trigger button
to turn the instrument on, the temperature reading will
appear. As long as the trigger button is pressed, the
temperature will continuously update, and the SCAN icon
will flash. The selected emissivity will be displayed above
the temperature reading. f the Mode is set to M N, MAX,

d F or AVG, the small numeric display in the bottom right
corner will also update. See MODE Functions for more
detail. When you release the trigger button, the last
reading will remain on the display. The SCAN icon will
change to HOLD.
Switching Temperature Units
To switch between °F and °C, press and hold the red
MODE button until you hear a beep.
Auto Shut Off and Lock
After approximately 7 seconds of non-use the thermometer
will automatically turn off, unless the lock feature has been
enabled. To enable the lock feature, press and hold the
Laser/Backlight button until you hear a beep. To disable it,
press and hold the red MODE button until SCAN changes
to HOLD. The Lock feature can be used if hands-free
operation for long periods of time is desired.
Laser Pointer and Backlight
To turn the laser pointer and backlight on and off, first
press and release the trigger button to turn the
thermometer on. Then press the Laser/Backlight button to
cycle through combinations of laser and backlight settings:
1. Laser OFF, backlight OFF, 2. Laser OFF, backlight ON, 3.
Laser ON, backlight OFF, 4. Laser ON, backlight ON.
When the laser is enabled, the icon appears on the
LCD display. The last laser/backlight setting chosen will be

remembered after the thermometer turns off. Both laser
and backlight reduce the battery lifetime.
Distance to Spot Size Ratio
The distance-to-spot ratio of the infrared thermometer is
20:1. This means that the spot diameter at a distance of 20
inches is 1 inch (25.4 mm). To measure a smaller spot area,
move the thermometer closer to the target and use the
distance-to-spot ratio of 20:1 to estimate the spot size. For
instance, at a target distance of 10 inches, the spot size is
0.5 inch (12.7 mm). The further away the target, the greater
the spot size. Make sure the target area you want to
measure is larger than the spot size.

MODE Functions
The red MODE button can be used to cycle through a
number of advanced features of the instrument. These
features are explained below.
Maximum, Minimum, and Average Temperature (MAX,
MIN, and AVG) and MAX-MIN Difference (dIF)
While the trigger button is held down for scanning the
temperature of various surfaces, the thermometer
continuously tracks and updates the maximum (MAX),
minimum (M N), and average (AVG) temperatures, as well
as the difference between MAX and M N (d F). These
values can be recalled in HOLD mode by pressing the red
MODE button several times and are retained in memory
until a new measurement is taken.
High and Low Alarms (HAL and LAL)
Two temperature alarm set points can be programmed:
High Alarm (HAL) and Low Alarm (LAL). While
temperatures are being scanned (trigger button held
down), if the temperature is lower than the LAL value or
higher than the HAL value, the instrument will beep. The
alarm set points can be programmed by pressing the
MODE button until HAL or LAL appear on the LCD
display. Use the UP and DOWN buttons to select the
desired temperature for each set point. Holding the UP or
DOWN button pressed will change the displayed
temperature set point at increasing increments.

Emissivity (EMS)
The emissivity ε is displayed in the top right corner of the
LCD display (e.g. ε=0.95). To change it, press the MODE
button until the mode indicator changes to EMS. Then use
the UP and DOWN buttons to select the desired emissivity
in 0.01 unit increments (range 0.10 to 1.00.)
Emissivity of a material is the ability of its surface to emit
thermal radiation. More accurately, it is the ratio of the
energy radiated from a material's surface to that radiated
from a perfect emitter (black body) at the same
temperature and under the same conditions. The
emissivity of a surface depends on the material and on the
nature of its surface. For instance, a polished metal surface
has a lower emissivity than an oxidized metal surface.
Since R thermometers calculate the surface temperature of
an object by sensing its emitted thermal radiation it is
important to take emissivity into account. A polished metal
object will emit less thermal radiation than an object with a
flat black finish at the same temperature, and thus appear
colder. The temperature displayed by the R thermometer
for the polished metal object would therefore be inaccurate,
unless the instrument’s emissivity setting is adjusted to
match the emissivity of the object.
Emissivity of a material surface is difficult to estimate since
it depends on its texture, color, and temperature. The table
provided here should only be used as a guideline. A good
default setting is ε=0.95, which is also used by R
thermometers that do not allow the emissivity to be
adjusted. f you need to take accurate readings for a
specific material often, you can measure the material

surface with an accurate contact thermometer (or the
included Type K probe) and then adjust the emissivity
setting of your R thermometer until its reading matches
the temperature reported by the contact thermometer. You
can then use the emissivity for subsequent measurements
of the same material. Alternatively, you can cover
materials with low emissivity with masking tape or flat
black paint. Make sure to allow the tape or paint to reach
the temperature of the material before taking a
measurement.

Log Feature (LOG)
The thermometer can store up to 20 readings in memory.
This feature is useful when multiple measurements are
taken that need to be recorded for future review.
To store a single reading, first make sure the thermometer
is in HOLD mode (not scanning.) Press the MODE button
multiple times until the LOG symbol appears in the bottom
left corner of the LCD display. Then use the UP and
DOWN buttons to select the memory location (01 to 20).
Press the Laser/Backlight button to store the currently
displayed temperature value in the selected memory
location. Pressing it again will clear the location. Press the
UP and DOWN buttons to access additional memory
locations to recall previously stored values or update them
with new values.

Measurements with Type K Thermocouple Probe (TK)
nsert the Type K thermocouple probe into the socket at the
base of the instrument. Bring the thermocouple probe tip
into contact with the object to be measured. Turn on the
instrument by pressing the trigger button. Press the MODE
button until TK appears on the display. The temperature
measured by the thermocouple probe will be displayed in
the bottom right corner of the LCD display.
