Congratulations!

You are now the owner of a new Therm-App® MD world-class thermal imaging device which includes

hardware and software components (the “Product”).

1Overview

Therm-App® MD is an Android-supported thermographic imaging device for elevated body temperature

(EBT) measurement, specifically calibrated to measure temperature. The Therm-App sensor is based on

α- Si bolometer 17µ 384x288 pixels.

2Disclaimer

Therm-App MD does not detect fevers or illness in any way. It is not a medical diagnostic tool and has

not been approved by a medical professional. Any individual tested and flagged should be double-

checked using an approved medical device.

Notes:

1) The measurement should not be solely or primarily relied upon to diagnose or exclude a

diagnosis of COVID-19, or any other disease.

2) Elevated body temperature in the context of use should be confirmed using secondary

evaluation methods (e.g., an NCIT or clinical grade contact thermometer)

6.1 Preparation

For best performance, the ambient room temperature should be 25°c (77°F).

For optimal performance wait 40 minutes or more from start-up, to allow the Therm-App to reach an

initial steady temperature state.

In order to establish a baseline temperature, have 3 healthy people with regular temperatures pass in

front of the camera. Calculate from the highest temperature of the 3 people and set the Compensation

to bring the temperature to be 36.5°c (97.7°F). For example, if the highest temperature is 34°c (93.2°F)

set the compensation to be 2.5°c (4.5°F).

Set the temperature dial to the temperature you want to start getting alerts, for example 38°c (100.4°F)

(see Configuring the Alert for instructions).

Note:

Changing the compensation does not affect the threshold. The threshold should be determined by the

temperature after the compensation. For example, if you want to be alerted at 38°c (100.4°F) and above,

you set the threshold to 38. If over time, you change the compensation, for example, because of the

weather warming during the day, you do not have to change the threshold.

6.2 Quick Access Menu

This menu allows you to quickly select:

◼

Imaging Mode [1] –Thermography or Night Vision mode.

◼

Emissivity and Reflected Temperatures [2]

(see thermography settings).

◼

Turn on Temperature alerts [3]

◼

Palette [4]

◼

Configure Temperature Alerts [5]

After you have turned on temperature alerts [3], you can set a

threshold for Therm-App® to start flash a red alert when measuring

temperature above this threshold (flame icon)

In the example on the right side, the temperature threshold has been

set to 38 °c (100.4°F).

Click on Alert

◼

Two boxes will appear on the screen with small circles on each

corner.

◼

Click and drag the boxes to the region of interest. Each box can be

dragged to any position on the screen.

◼

Click and drag the corners of the boxes to resize the area of

interest.

◼

In case of overlap between the boxes, the alert will function

mutually in the overlapped area.

◼

To cancel alerts, press the NONE option.

6.4 Main Menu Options

Imaging Mode

◼Night Vision –This mode maximizes the difference

between hot objects and their surrounding and is used for

night-time detection of various targets. Imaging Mode –

switches between "Night Vision" and "Thermography"

modes.

◼Thermography –Image pixels are colored in relation to

their temperature. On the default rainbow palette, blue

indicates the coldest measured temperature and red

represents the hottest temperature measured. This mode

is used for searching for temperature differences on the

scanned scene.

6.5 Thermography Settings

◼Units –select between Celsius and Fahrenheit.

◼Emissivity –Emissivity is the ability of the surface of a

material to emit energy as thermal radiation. The

emissivity value (0 –1) represents the ratio of energy

radiated by the observed material to the energy

radiated by a black body at the same temperature.

Typical emissivity for human skin is: 0.98.

To adjust the emissivity ratio:

1. Tap the EMISSIVITY option on the screen.

2. Scroll to the correct emissivity ratio and tap the

SET button

◼Reflected Temperature –Reflected temperature

represents the energy emitted by the surrounding

objects and reflected by the measured surface.

To adjust the reflected temperature:

•Tap the Reflected Temperature option on

the screen.

•Scroll to the correct temperature and tap

the SET button

◼Scale Truncation –Within every image frame, the

temperature span is calculated and displayed on

the top of the thermography image. Use this

parameter to define the minimum number of

pixels (defined by percentage) required to affect

the temperature span calculation.

◼To adjust the truncation value:

•Tap the Scale Truncation option on the

screen.

•Scroll to the correct temperature and tap

the SET button.

temperature threshold. (recordings are stored under date

and time file name).

oVideo Streaming: Will stream to a preset location for as long

as the temperature is met or above the preset temperature

threshold.

oVibrate: Will vibrate every time a measured temperature is

met or above the preset temperature threshold (This option

is available only for a mobile device).

oPlay alert: Plays an audio file alert every time a measured

temperature is met or above the preset temperature

threshold.

Note: for best performances, it is recommended to activate not

more than three alert actions simultaneously.

➢Advanced Parameters:

oDetection Duration (Seconds): Sets how long the object

needs to be in the set field to trigger the alert.

oAlert Delay (Seconds): How long Therm-App® should wait to

send consecutive alerts after the first alert is triggered (time
