TAKING MEASUREMENTS
To take a temperature measurement using your
UD70, you simply point the aperture at an object
and pull the trigger. The object's temperature will
show up on the display and update at a rate of
approximately 2 times per second. There will be
a delay of approximately one-second between
the time you initially pull the trigger and the time
the display comes on. The 60-second auto-hold
initiates at the moment you release the trigger.
The maximum temperature is viewed beside the
"MAX" icon.
NOTE: this thermometer will automatically shut off
if left idle for more than 15 seconds.
Follow these general guidelines to ensure you get
the most accurate readings possible:
• Be sure the measured object fills the "spot"
indicated by the circular laser targeting. The
distance to spot ratio for the UD70 is 12:1.

This shows the one-foot spot fitting within
the one-foot target area. At this distance, and
anything closer, the target's temperature will be
accurately measured.
NOTE: if the two-foot diameter spot includes
unwanted objects in the background that are not
part of the one-foot target, the temperature of
the background objects will be figured in with
the target's temperature and cause errors in your
measurements.
Target surface - >1' sq.
Scanned spot - >1' diam.
Distance to target
• When comparing temperatures of similar objects
that are far away, take your measurements at the
same distance and angle to the target each time.
• When looking for abnormally hot or cold targets
it may be acceptable to include background objects
so long as the temperatures in the background and
your methods are consistent.
• Consider the emissivity of the objects you are
measuring.
• Prepare a surface for measurement. Infrared
thermometers measure only the outer surface of an
object. If emissivity is affecting the measurement,
or you have difficulty putting the object in the
sensor's line-of-site, you may need to prepare a
surface that's easy for the infrared thermometer to
read. A piece of masking tape is a good target and
it will rapidly take on the temperature of the object
it is attached to.
• Be aware that you cannot measure the temperature
of air between the Infrared thermometer and an
object. Air vents (registers) are quick to take on the
temperature of outlet air. However, you must aim
directly at the vent if you are measuring outlet air
temperature.
• Keep your infrared thermometer away from
strong electrical fields. When working near a strong
electrical field, like that under the hood of your
car, watch for unusual readings or an "over load"
indication. Often, you can move the thermometer
just a few inches to escape the influence of the
interference.
• Keep your UD70 within its use and storage
temperature range. Excessive heat or cold will
adversely affect the accuracy of your readings.
When the trigger is pulled the target's temperature
will be displayed in a near real-time mode (less
than 1/2 second between measurements). The
temperature will remain on the display for sixty
seconds after the trigger is released.
