Temperature
Select target within
probe’s specified
temperature range.
Ensure that the probe
is within the specified
ambient operating
range.
Replace the battery.
Restart the probe by
sliding switch to “OFF”
and then to “ON”, or
replace battery.
Target temperature is over
or under range.
The temperature of the
probe is near either the
high or low ambient op-
erating range limit.**
Battery power is low.
Sleep mode or battery is
dead.

SAFETY INFORMATION
The 80PK-IR complies with IEC Publication 1010-1-1990
including Amendment 1, CSA C22.2 No. 231, ANSI/ISA-
S82.01 and .03 Safety Standards.
WARNING
IF TARGET EMISSIVITY IS LESS THAN 0.95, THE
PROBE CAN INDICATE A TEMPERATURE LOWER
THAN THE ACTUAL TARGET TEMPERATURE.
AVOID TOUCHING THE TARGET; THERMAL BURNS
COULD RESULT.
CAUTION
•
Do not place the probe on or around hot objects
(
≥
70
°
C / 158
°
F). Heat may cause damage to the
probe case.
•
If the probe is exposed to significant changes in
ambient temperature (hot to cold or cold to hot),
allow 20 minutes for temperature stabilization
before taking measurements.
•
Do not operate the probe near large electrical or
magnetic fields, such as arc welders and induc-
tion heaters. These fields can cause measure-
ment errors.
•
Condensation may form on the lens when going
from a cold to hot environment. Wait 10 minutes
for condensation to dissipate before taking mea-
surements.
•
Connectors must only be plugged into miniature
Type K input jacks of a digital thermometer.
•
Do not touch or hold by the front cone. Tempera-
ture readings can be affected by heat from the
hand.
•
Equipment use not specified by the manufac-
turer may impair safety.
Emissivity
All objects emit invisible infrared energy. This ability, called
emissivity, is based upon the material that the object is
made of and its surface finish. Emissivity values typically
range from 0.10 for a very reflective object to 1.00 for a
black body. The probe senses this energy assuming that
the target has an emissivity value of 0.95. This value is
factory set in the probe. If the actual target emissivity is less
than 0.95, the indicated temperature could be less than the
actual target surface temperature. To correct for this, safely
coat the target with a substance with emissivity
≥
0.95 or
thermally bond a "target" with emissivity
≥
0.95 to the
surface to be measured.
Figure 1.
COMPATIBILITY
The probe is compatible with all digital thermometers that
accept standard miniature Type K polarized thermocouple
plugs with flat, in-line blades spaced 7.9 mm (0.312 in.)
center-to-center.
OPERATION
To take a measurement, perform the following steps:
1. Plug the yellow connector into the miniature Type K jack
on the thermometer.
2. Turn on the thermometer.
3. Slide the probe switch to “ON”.
4. Point the tip of the probe at the object to be measured.
5. Read the thermometer display. (Refer to Table 1 for
error conditions.)
NOTE
After 10 minutes of use, the probe automatically shifts
to Sleep mode (the display shows ambient tempera-
ture). Restart the probe by sliding the switch to “OFF”
and then to “ON” (see Table 1). Sleep mode extends
battery life. However, for maximum battery life, switch
the probe to the “OFF” position.
Measurement Considerations
•
For small target surfaces (13 mm (1/2 in.) or less), hold
the probe as close as possible without touching the
surface (no more than 50 mm (2 in.) away).
•
If the surface to be measured is covered by frost or other
material, clean it to expose the surface.

•
If target emissivity is less than 0.95, wait until the target
is at a safe temperature, then apply a high emissivity
coating to the surface (such as flat black paint or
masking tape.)
•
If the probe seems to be giving incorrect readings,
check the front of the probe. There may be condensa-
tion or debris obstructing the sensor; clean per "Front
Window Cleaning" instructions.
Display Codes
Under the conditions shown in Table 1, the thermometer
will alternate between displaying a reading and a Display
Code.
