Battery Charging and Replacement When the battery display symbol appears empty or close to empty, recharge the Lithium ion 3.7V/1400mAh rechargeable battery. Connect the supplied USB battery cable to the mini USB jack in the compartment above the measurement trigger and then connect the other end of the cable to an AC source. Charge time is approx. 2 hours. The battery is located in the compartment behind the handle panel and beneath the meter’s trigger. The panel can be released and folded down as shown in the diagram. Replace the battery if necessary with one of the same type and specifications and close the battery compartment cover. You, as the end user, are legally bound (Battery ordinance) to return all used batteries and accumulators; disposal in the household garbage is prohibited! You can hand over your used batteries / accumulators at collection points in your community or wherever batteries / accumulators are sold! Disposal: Follow the valid legal stipulations in respect of the disposal of the device at the end of its lifecycle 18 VIR50-EU-EN v2.3 5/14 IR Measurement Notes 1. The object under test should be larger than the spot (target) size calculated by the field of view diagram (printed on the side of the meter and in this guide). 2. Before measuring, be sure to clean surfaces that are covered with frost, oil, grime, etc. 3. If an object's surface is highly reflective, apply masking tape or flat black paint to the surface before measuring. Allow time for the paint or tape to adjust to the temperature of the surface it is covering. 4. Measurements through transparent surfaces such as glass may not be accurate. 5. Steam, dust, smoke, etc. can obscure measurements. 6. The meter automatically compensates for deviations in ambient temperature. However, it can take up to 30 minutes for the meter to adjust to extremely wide changes. 7. 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. Field of View The meter’s lasers converge at a distance of 50 inches (127cm) which is the optimum measurement distance for this meter. At this distance the measurement spot has a 1 inch (2.54cm) diameter. The Distance to Spot Ratio determines the measured spot size for the distance used. For this meter the ratio is 50:1 or: 1”(2.54cm) spot @ 50” (1.27m), 2”(5.08cm) spot @ 100”(2.54m) or 0.5”(1.27cm) spot @ 25”(0.64m). 50” / 127cm 19 VIR50-EU-EN v2.3 5/14 Emissivity and IR Measurement Theory IR Thermometers measure the surface temperature of an object. The thermometer’s optics sense emitted, reflected, and transmitted energy. The thermometer’s electronics translate the information into a temperature reading which is then displayed on the LCD. The amount of IR energy emitted by an object is proportional to an object's temperature and its ability to emit energy. This ability is known as emissivity and is based upon the material of the object and its surface finish. Emissivity values range from 0.1 for a very reflective object to 1.00 for a flat black finish. For the VIR50, the emissivity is adjustable from 0.1 to 1.00 (see the Measurement Settings section earlier in this User Guide). Most organic materials and painted or oxidized surfaces have an emissivity factor of 0.94. When in doubt, set the emissivity to 0.94.
