VR-308D
I.

Introduction

This infrared thermometer is used for measuring the temperature of the object's surface, which is
applicable for various hot, hazardous or hard-to-reach objects without contact safely and quickly.
This unit consist of Optics, Photo sensor, Signal amplifier, Processing circuit and LCD Display.
The Optics collected the infrared energy emitted by object and focus onto the Sensor. Then the
sensor translates the energy into an electricity signal. This signal will be turned out to be digital
shown on the LCD after the signal amplifier and processing circuit.

Accessories

Open the bag, then take the item out, and check below accessories:
1.operation manual
2.9V battery
If you found that there's anything missing or damage please contact your supplier.
III. Warning & Cautions
1. Warning:
To avoid the potential situation which may cause harm or damage to people, please pay attention
to the following instructions:
1). Do not point laser directly at eye or indirectly off reflective surfaces.
2). The unit cannot measure through transparent surfaces such as glass or plastic. It will measure
the surface temperature of these materials instead.
3).Steam, dust, smoke, or other particles can prevent accurate measurement by obstructing by the
units optics.
2. Cautions:
Infrared thermometer should be protected for the following:
1). EMF (electro-magnetic fields) from arc welders, induction heaters.
2). Thermal shock (cause by large or abrupt ambient temperature changes allow 30 minutes for unit
to stabilize before use).
3). Do not leave the unit on or near objects of high temperature.
IV.

Distance ratio

1. When take measurement, pay attention to the Distance ratio. As the Distance (D) from the target
surface increases, the spot size (S) of the area measured by the unit becomes larger.
The Distance ratio of the unit is 50:1.
This unit is equipped with a laser, which is used for aiming.
2. Field of view: Make sure the target is larger than the unit's spot size. The smaller the target the
closer measure distance. When accuracy is critical, make sure the target is at least twice as large
as the spot size.
