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 
r. 
large
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 
trigger, LCD display reading & battery icon. Release 
the trigger and the reading will hold for 7 seconds.

2. Locating a hot spot aim the thermometer outside the 
area of interest, then scan across with up and down 
motions until you locate the hot spot.(please turn on the 
laser to for accurate measuring) 
3. Diagram description 
(1) Trigger: Press for turn on, and then display test result 
and hold data 7 seconds automatically ("HOLD") after 
unclamping switch. Turn off automatically after 10 
seconds without operate.
(2) Laser pointer button :press it for turn on laser 
pointer, press again for turn off. 
Back light /Up button :In “Alarm temperature” 
(3) 
and “setting emissivity” mode for adjust value up. In 
other mode for turn on back light. When product 
working, press it for turn on back light, press again for 
turn off.  
MODE button:Press MODE button for cycle options 
(4) 
- MAX - AVG - MIN –HAL –LAL mode  
A、MAX:Measure maximum data current; 
B、MIN:Measure minimum data current;;  
C、AVG :Calculate the average of all measure data;  
D、HAL:Alarm of high temperature. Option HAL mode,  
press “ UP or DN” button for set alarm temperature. 
When LCD display ”H” means measure result exceeded 
the alarm temperature;  
E、LAL:Alarm of low temperature. Option HAL mode, 
press “ UP or DN” button for set alarm temperature. 
When LCD display ”L” means measure result under the 
alarm temperature; 
T/ DN button :In “Alarm temperature” and “setting 
(5) 
emissivity” mode for adjust value down . When turn on 
product and press direct for ℃/  select. 
SET button:Press for setting emissivity. And press 
(6) 
“UP or DN” for adjust from 0.1~1.0. Press SET button 
again for exit setting mode.

(8) Battery door: When replace battery, please using 
the finger indents to pull open the battery door. 
3. Maintenance 
1) Lens cleaning: Blow off lose particles using clean 
compressed air. Gently brush remaining debris away 
with a moist cotton cloth. 
2) Case cleaning: Clean the case with a damp 
sponge/cloth and mild soap. 
3) Please take out the battery when not using for a long 
time. 
Note: 
1) Do not use solvent to clean lens. 
2) Do not submerge the unit in water.
