ATD-701
Non-contact Infrared Thermometer
Instruction manual
1. Introduction
Compact, rugged and easy to use. Just aim and push the
button, read target surface temperatures in less than a
second. Safely measure surface temperatures of hot,
hazardous or hard-to-reach objects without contact.
How it works
Infrared thermometer measures the surface temperature of
an object. The unit’s optics sense emitted, reflected, and
transmitted energy which is collect and focused onto a
detector. The unit’s electronics transmitted energy which is
display on the unit. For increased ease and accuracy the
laser pointer makes aiming even more precise.
Cautions
Infrared thermometer should be protected from the
following:
--EMF (electro-magnetic fields) from arc welders, induction
heaters.
--Thermal shock (cause by large or abrupt ambient
temperature changes allow 1 hour for unit to stabilize before
use).
--Do not leave the unit on or near objects of high
temperature
.
Warning
Do not point laser at eye or indirectly off reflective surfaces.
1. When take measurement, point thermometer toward
the object to be measured and hold the red trigger. The
object under test should be larger than the spot size
calculated by the field of view diagram.
2.
Distance
＆
spot size: As the distance from the object
increase, the spot size of measuring area becomes
large
r.
3. Field of view: Make sure the target is larger than the
unit’s spot size. The smaller the target, the closer
measuring distance. When accuracy is critical, make
sure the target is at least twice as large as the spot size.
4. Emissivity: Most organic materials and painted or
oxidized surfaces have an emissivity of 0.95. Inaccurate
readings will result from measuring shiny or polished
metal surfaces. To compensate, cover the surface to be
measured with masking tape or flat black paint.
Measure the tape or painted surface when the tape or
painted reach the same temperature as the material
underneath.
2. Quick start instruction
1. Press battery door clip, install battery correctly. Pull the
