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.

The built-in laser pointer increases target accuracy while the backlit LCD and handy push-buttons combine for convenient, ergonomic operation. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.

6. For accurate readings, wait 30 seconds after powering on to allow the meter to stabilize.

button to switch the unit OFF.

Measurement Modes

The meter has four (4) measurement modes: Video + Infrared, Infrared-only, Dew Point, and Datalogging mode. When the meter is switched ON, the first screen that appears is the mode selection screen. Use the ▲/▼ buttons to highlight the desired mode and then press the ENTER button to access the mode.

Video + Infrared mode: the meter functions as an IR meter with the camera capabilities;

Infrared-only mode: the meter functions as an IR meter only;

Dew Point mode: the meter shows the Dew Point temperature value;

Datalogging mode: the meter functions as a measurement storage/retrieval device.

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)

In the Video + IR mode, press the save the photo (the SAVE soft-key will appear above the up arrow button after the photograph is taken). Press the ▼button to cancel the photo .

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.

Dew Point Temperature Mode

In the Dew Point mode the meter displays the Dew Point temperature measurement along with the

IR temperature value. Press and hold the measurement trigger to take a measurement.

In the Dew Point mode the percentage bargraph indicates how close the IR temperature is to the Dew Point temperature. At 100%, the two values are identical.
