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

and thickness, distance from the source, and other factors may effect
operation. Always verify live voltage using other methods before working on
electrical circuits. · The non-contact voltage detector operates when the
meter is set to
any measuring function. The detector does not operate when Auto Power Off
turns the meter off or when the rotary function switch is set to the Off
position. · Slowly move the detector probe closer to the conductor being
tested. · If AC voltage within the specified range is present, the indicator
light will illuminate. NOTE: The detector is designed with high sensitivity.
Static electricity and other sources of electrical energy may randomly
activate the detector. This is normal operation. The detector only activates
the indicator light when AC voltage is present. It does not indicate the
voltage level on the LCD.

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
