8. The thermal imager's FOV (Field of view) is 21 by 21 degrees.
9. FOV is the largest area that your imager can see at a set distance.
10. This table lists the horizontalFOV, vertical FOV and IFOV for lens.
Focal Length Horizontal FOV
7,5 mm 21°
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 ( = 1/ IFOV ) is the calculated spot size based on the pixel theoretical
theoretical theoretical
theoretical 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 34um.
Horizontal FOV is 21°, Vertical FOV is 21°, the IFOV is 34um/7.5mm = 4.53mrad;
D:S ( = 1/ IFOV ) = 220:1

D:S (= 1/ IFOV ) is the spot size needed to provide an accurate measure

target need to be 2 to 3 times larger than that determined by the calculated theoretical D:S.

5.3. Using the Multimeter with the thermal imager

On IR+DMM mode, MODE key, RANGE key, HOLD key and REL Function is same DMM
mode.
• Capturing MAXMIN Values on IR+DMM mode
1. To activate the maxmin mode, press the softkey labeled
, and display max value.
2. If the Meter is already in the maxmin function, then
Press the key to display min value, then Press the
key to display current measurement value.
next press again display max value.
3. The Press and hold the key for more than 1 second
tocauses the Meter to turn off maxmin.
• Capturing Peak Values on IR+DMM mode
1. To activate the peak mode, press the softkey labeled
and display Peak max value.
2. If the Meter is already in the peak function, then Press
the key to display Peak min value, then Press the
key to display current measurement value. next press
again display Peak max value.
3. The Press and hold the key for more than 1 second to
causes the Meter to turn off peak.
