Introduction

The Southwire 31011F Infrared (IR) Thermometer measures
surface temperature from -4° to 752°F (-20° to 400°C). The IR
thermometer has a 10:1 Distance-to-Spot ratio which means
that when you aim the thermometer at a surface that is
10-inches away, the thermometer gathers temperature
information from a measurement area (“spot” size) of 1 inch in
diameter. See diagram below. If the IR thermometer is
moved further from the object surface, the measurement area
or spot size increases.

To avoid damaging the thermometer or the equipment under
test protect them from the following:
EMP (electro-magnetic fields) from arc welders, induction
heaters, etc
Static electricity
Thermal shock (caused by abrupt ambient temperature
changes)
Do not leave the thermometer on or near objects of high
