of the instrument. The selected function is displayed on the
bottom line of the LCD. Each parameter is listed below with a
detailed account of its use. Press the MODE button to step from
one parameter to the next.
EMS (Emissivity Value)
To change the emissivity value, use the UP and DOWN
arrows (the range is 0.10 to 1.00). The current emissivity
setting is always shown at the top of the LCD display. A
setting of 0.95 covers about 90% of all applications.
Emissivity is discussed in a dedicated section of this manual.
MAX (Maximum function)
In the MAX mode, only the highest reading encountered in the
current measurement session is displayed
MIN (Minimum function)
In the MIN mode, only the lowest reading is displayed
DIF (Max minus Min value)
In the DIF mode, the MAX less the MIN is displayed.
AVG (Average value)
In the AVG mode, all of the readings in the current
measurement session are averaged and the value is
displayed.
HAL (High Alarm setting)
The temperature that, when exceeded, causes the
audible/visual alarm to trip.
LAL (Low Alarm setting)
The temperature that, when exceeded high to low, causes the
audible/visual alarm to trip.
T k (Type-K contact thermocouple sensor function)
The temperature reading of the Type-K contact probe is
shown next to the ‘T k’ icon display. If the sensor is not
correctly inserted to the meter the display will show all dashes
‘-----‘. The supplied thermocouple is rated for 482°F (250°C).
For higher measurements you can purchase a high
temperature thermocouple from www.craftsman.com that is
rated to the full range of this Infared thermometer.

Automatic Emissivity Adjustment
The 81998 has the ability to automatically calibrate the
emissivity setting. However, in order to do so, the temperature of
the measured surface must be above 212ºF (100ºC).
Follow the steps below to use the automatic emissivity
adjustment feature:
1. Press the MODE button until the EMS (Emissivity) icon
appears on the lower LCD line.
2. Press and hold the Laser/Backlight button until the EMS icon
begins to blink and the emissivity value is displayed as “___”.
3. The IR temperature will be displayed on the middle line of
the LCD and the Type-K temperature will be displayed on
the lower LCD line.
4. Touch the Type-K sensor to the surface and, at the same
time, take an IR reading.
5. When both the IR and the Type-K measurements stabilize,
press the UP or DOWN arrow button. The new emissivity
value will now be displayed.
6. Proceed to take measurements.
11
Over-range Indicator
If the temperature measurement exceeds the specified
temperature range, the thermometer will display dashes in place
of a temperature reading.
High and Low Alarm Feature
The 81998 has an alarm feature where a High Alarm setting and
a Low Alarm setting can be programmed by the user. When
either Alarm point is reached the meter will alert the user via an
audible beep and LCD display icon. Follow the steps below:
1. Press the MODE button until the HAL (High Alarm)
parameter is displayed. Use the UP and DOWN arrow keys
to set the desired High Alarm setting.
2. Press the MODE button until the LAL (Low Alarm)
parameter is displayed. Use the UP and DOWN arrow keys
to set the desired Low Alarm setting.
3. When an alarm limit is reached, the audible alarm will
sound and the display icon HIGH or LOW will appear in the
lower right hand corner of the LCD.
4. Note that if the bottom dip switch (located in the battery
compartment) is set to OFF, the audible alarm will be
disabled.

IR Measurement Notes
1. The object under test should be larger than the spot (target)
size calculated by the Distance-to-spot ratio diagram (printed
on the side of the meter and in this guide).
2. Before measuring, be sure to clean surfaces that are
covered with frost, oil, grime, etc.
3. If an object's surface is highly reflective, apply masking tape
or flat black paint to the surface before measuring. Allow
time for the paint or tape to adjust to the temperature of the
surface it is covering.
4. Measurements through transparent surfaces such as glass
may not be accurate.
5. Steam, dust, smoke, etc. can obscure measurements.
6. The meter automatically compensates for deviations in
ambient temperature. However, it can take up to 30 minutes
for the meter to adjust to extremely wide changes.
7. To find a hot spot, aim the meter outside the area of interest
then scan across (in an up and down or side to side motion)
until the hot spot is located.
8. IR measurements cannot be made through glass.
13
Distance-to-spot ratio
The meter’s distance-to-spot ratio is 13:1. For example, if the
meter is 13 inches from the target (spot), the diameter of the
target must greater than 1 inch. Other distances are shown in
the field of view diagram. Measurements should normally be
made as close as possible to the device under test. The meter
can measure from moderate distances but the measurement
may be affected by external sources of light. In addition, the spot
size may be so large that it encompasses surface areas not
intended to be measured.

Emissivity and IR Measurement Theory
IR Thermometers measure the surface temperature of an object.
The thermometer’s optics sense emitted, reflected, and
transmitted energy. The thermometer’s electronics translate the
information into a temperature reading which is then displayed
on the LCD.
The amount of IR energy emitted by an object is proportional to
an object's temperature and its ability to emit energy. This ability
is known as emissivity and is based upon the material of the
object and its surface finish. Emissivity values range from 0.1 for
a very reflective object to 1.00 for a flat black finish. For the
Model 81998, the emissivity is adjustable from 0.1 to 1.00. Most
organic materials and painted or oxidized surfaces have an
emissivity factor of 0.95. When in doubt, set the emissivity to
0.95.
