Introduction
The Digi-Sense Digital Multimeter with Thermal Imager and Bluetooth® Connectivity (model 20250-66) allows you to transmit data directly to your AndroidTM or iOS® device using our free D/S T-View app. Now you can view data at a safe distance from potentially hazardous parameters or even use your smart device as a real-time secondary display for checking measurements, eliminating the need to write down readings on paper. The results are automatically stored in the app with a date-and-time stamp and can be saved as a CSV file and emailed for future reference, manipulation, or analysis to help determine trends and conditions over a long period of time. You can also use the app to attach photos and notes to the records creating a clear reference point for your work–ideal for record keeping at large sites.
Setup is simple. Download the free D/S T-View app to your Android or iOS device. Place the meter in Bluetooth mode and open the app on your smart device. The meter will be sensed by your device and be listed as an available source that you can select. Once selected, the measured electrical data is displayed on your device and some of the instrument functions can be accessed. A full description of its operation is available for download in the app.
The Digital Multimeter with Thermal Imager provides fast A/D converting sampling time, high accuracy with data logging and trend capture features. This instrument is fully tested and calibrated to NIST-traceable standards for reliable measurements right out of the box, saving you time and money.

3. The display will show the temperature measurement in the upper left hand corner for the targeted area along with the currently selected emissivity value.

4. In the Thermal imaging mode, the laser pointer and display cross hairs can be used to assist in targeting. Tools can be switched ON or OFF in the Setting menu.

5. In the Thermal imaging mode, the highest temperature will be auto marked by a red cross, and the lowest temperature will be auto marked by a blue cross, the two spots can be switched ON or OFF in the Setting menu.

6. In the Thermal imaging mode, the meter continues to operate normally as a multimeter allowing any of the electrical functions to be used.

7. Press the HOLD button to hold the thermal image frame, then long press the HOLD button. You will capture the screen and save a bitmap with measure data into SD card. The saved bitmap later can be analyzed by PC software or smartphone apps.

8. The thermal imager FOV (Field of View) is 21 by 21°.

9. FOV is the largest area that your imager can see at a set distance.

10. This table lists the horizontal FOV, vertical FOV and IFOV for lens.

Focal Length 7.5mm

Horizontal FOV 21°

Vertical 21°

FOVIFOV 4.53mrad

IFOV (Instantaneous Field of View) is the smallest detail within the FOV that can be detected or seen at a set distance, the unit is rad. The formula is this:

IFOV = (Pixel Size)/(Lens focal length);
D:S theoretical ( =1/ IFOVtheoretical) is the calculated spot size based on the pixel size of the Thermal Imager detector array and lens focal length.
Example: if thermal imager uses 9mm lens, because the Pixel Size of detector is 34µm, horizontal FOV is 21°, vertical FOV is 21°, and the IFOV is 34µm/7.5mm = 4.53mrad;

80m 80m
220m

Spot Size=100.00cm*100.00cm (Based upon IFOVtheoretical)
21° 21°

D:Stheoretical ( = 1/ IFOVtheoretical) = 220:1

D:Smeasure ( = 1/ IFOVmeasure) is the spot size needed to provide an accurate temperature measure. Typically, D:Smeasure is 2 to 3 times smaller than D:Stheoretical, which means the temperature measurement area of the target needs to be 2 to 3 times larger than that determined by the calculated theoretical D:S
