EXTECH INSTRUMENTS CAUTIONS 
Improper use of this meter can cause damage, shock, injury or death. Read and understand this user manual before operating the meter. 
Always remove the test leads before replacing the battery or fuses. 
Inspect the condition of the test leads and the meter itself for any damage before operating the meter. Repair or replace any damage before use. 
Use great care when making measurements if the voltages are greater than 25VAC rms or 35VDC. These voltages are considered a shock hazard. 
Always discharge capacitors and remove power from the device under test before performing Diode, Resistance or Continuity tests. 
Voltage checks on electrical outlets can be difficult and misleading because of the uncertainty of connection to the recessed electrical contacts. Other means should be used to ensure that the terminals are not "live". 
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired. 
This device is not a toy and must not reach children’s hands. It contains hazardous objects as well as small parts that the children could swallow. In case a child swallows any of them, please contact a physician immediately 
Do not leave batteries and packing material lying around unattended; they can be dangerous for children if they use them as toys 
In case the device is going to be unused for an extended period of time, remove the batteries to prevent them from draining 
Expired or damaged batteries can cause cauterization on contact with the skin. Always, therefore, use suitable hand gloves in such cases 
See that the batteries are not short‐circuited. Do not throw batteries into the fire. 
Do not directly view or direct the laser pointer at an eye. Low power visible lasers do not normally present a hazard, but may present some potential for hazard if viewed directly for extended periods of time 3

Set the function switch to the IR Temp position. Aim the infrared sensor (rear of the meter) at the surface to be measured. Press the button in the center of the rotary function switch to turn on the laser pointer and identify the surface spot to be measured. The area of the surface to be measured must be larger than the spot size as determined by the distance to spot size specification. Read the temperature in the display. Note: See the “Temperature Units” paragraph to select oF or oC WARNING: Do not directly view or direct the laser pointer at an eye. Low power visible lasers do not normally present a hazard, but may present some potential for hazard if viewed directly for extended periods of time. IR Spot to Distance Diagram The 8:1 spot to distance ratio determines the size of the measured surface area with respect to the distance the meter is held away from the surface. Diameter of spot

Distance to object
IR Measurement Notes 1. The object under test should be larger than the spot (target) size calculated by the field of view diagram. 2. If the surface of the object under test is covered with frost, oil, grime, etc., clean before taking measurements. 3. If an object's surface is highly reflective, apply masking tape or flat black paint to the surface before measuring. 4. The meter may not make accurate measurements through transparent surfaces such as glass. 5. Steam, dust, smoke, etc. can obscure measurements. 6. To find a hot spot, aim the meter outside the area of interest then scan across (in an up and down motion) until the hot spot is located. 8
