User’s Manual Dual Laser Video IR Video Thermometer MODEL VIR50
Introduction Congratulations on your purchase of the Video IR Thermometer. This meter is capable of making non-contact (infrared) and contact (thermocouple) temperature measurements. The built-in camera offers still image and video capturing functionality for documenting measurement locations. The meter includes a micro SD card slot for offloading still images and video.

Operation Power ON and OFF 1. The instrument is powered by one (1) rechargeable battery (3.7V). The battery is housed in the compartment in the meter’s handle. 2. The supplied battery charger connects to the USB port on the instrument (in the compartment above the measurement trigger). 3. Once the battery is charged, Press and Hold the instrument ON. 4. Press and Hold the button for 5 seconds to switch the button to switch the unit OFF. 5.
Video + IR mode In the Video + IR Mode the meter can measure IR temperature, air temperature, humidity, dew-point temperature, and wet bulb temperature, along with full use of the video camera capabilities. The IR Maximum (MAX) Temperature, IR Minimum (MIN) Temperature, IR Differential (DIF) Temperature, and the IR Average (AVG) Temperature can also be displayed. Press and hold trigger to measure the temperature. Capturing Still Images (Photographs) button to take a photograph.
IR-only mode In the IR-only Mode the meter can measure IR temperature, air temperature, air humidity, dew-point temperature, and wet bulb temperature but without the video camera capabilities. The IR Maximum (MAX) Temperature, IR Minimum (MIN) Temperature, IR Differential (DIF) Temperature, and the IR Average (AVG) Temperature can also be displayed. Press and hold trigger to measure the temperature.
Datalogging Mode The datalogger automatically records readings to memory at a programmed interval. In the Datalogging mode, the high/low alarm values, low alarm value, datalogging interval sampling rate (time), can be configured. Once configured, press the trigger to start logging. The unit will automatically record data at the specified sampling time. Press the ESC buttom to exit the DATALOG mode, the meter will automatically save the data to a file.

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.
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.
