Safety and Caution Notes Therm-App Operation Manual
Safety and Caution Notes
Attach Therm-App to your mobile device with care. Do not use any external tools as too much
pressure might mark or damage your mobile device. Secure locking knob using your fingers only.
Therm-App uses specific factory-prepared calibration data. If, during prolonged field usage of
Therm-App, a degraded performance is noted, we recommend that you send the Therm-App
device, for re-calibration. Please contact our support team at http://www.therm-app.com for further
instructions.
For the most accurate temperature measurement results, it is recommended to wait at least five
minutes after Therm-App starts and before starting temperature reading.
Therm-App manuals are updated from time to time, and product-critical notifications are published
occasionally. To access the latest manuals and notifications, go to http://www.therm-app.com.
Therm-App is a Class B digital product
This product has been tested and found to comply with the limits for a class B digital product,
pursuant to Part 15 of the U.S. FCC Rules.
Some parts of Therm-App have sharp edges and could cause injury.
Read this document in full, as well as the warranty document provided with the product.
Do not drop Therm-App or apply pressure on the IR lens to avoid breaking the lens. If the IR lens
breaks, do not touch the broken pieces, the pieces. Touching the broken lens pieces can cause
injury.
Do not point the infrared detector (with or without the lens and lens cover) at intensive energy
sources, for example products that emit laser radiation, or the sun. This could damage the
detector.
Do not use Therm-App in a temperature environment higher than +50 degrees Celsius (+122
degrees Fahrenheit), unless specified otherwise in user documentation or technical data. High
temperatures can cause damage to the detector.
The Therm-App device is not sealed. Do not expose the Therm-App device to water, rain or dust.
Do not apply solvents or similar liquids to the detector or the lens.
The lens has a delicate anti-reflective coating. Clean the lens using a soft cloth applying very light
pressure.
During lens exchange, the IR detector is exposed. Avoid all contact with the detector. Do not
touch, clean or blow air on the detector. Replacement of the lens must be done in a clean, dry
area.
Do not use pneumatic system pressurized air to remove dust from the Therm-App device.
Pressurized air contains oil mist intended to lubricate pneumatic tools, this type of a pressurized
air could damage the detector and lens.
Power the Therm-App device with 5V DC connected through the micro USB connector only. Using
any other type of power source may damage the Therm-App device.
The Therm-App device is supplied with an appropriate USB-OTG cable. Use only the USB OTG
cable provided. Using any other types of cables could damage the equipment.
A label tamper is attached to one of the screws on the back of the Therm-App device. Removing
this label voids the warranty.
Temperature measurement is accurate in zoomed out mode only. If you pinch the screen for zoom
in the temperature reading will not be valid.
For more information, FAQ, and updated device compatibility views, please visit the Therm-App
website: http://www.therm-app.com.
As with most electronic products, Therm-App device must be disposed in an environmentally
friendly way, and in accordance with existing regulations for electronic waste. Please contact our
support team at http://www.therm-app.com for more details.

Imaging Mode
The Therm-App device image can be displayed in one of two modes.
To change the imaging mode:
1. Tap the Imaging Mode option on the Therm-App Settings screen.
2. Select one of the following modes:
Night Vision - displays video image using 256 shades of
gray. This mode displays more detailed image, useful for
human observation during surveillance and detection.
Thermography - image pixels are colored in relation to their
temperature. On the default rainbow palette, the blue
indicates the coldest measured temperature and red
represents the hottest temperature measured. This mode is
useful with applications searching for temperature
differences on the scanned scene. The color palette is
selectable.
Notes:
Temperature measurements are stabilized about five
minutes
after activating the Therm-App device.
Thermography measurement of temperatures calculation might
be
influenced by the environment of the measured objects
, the
surrounding objects reflected temperature,
and the measured object
emissivity.
Setting Thermography Color
When the Thermography mode is selected, the Therm-App device image
can be displayed using one of three palettes.
To change the selected palette:
1. Tap the Thermography Color option on the Therm-App Settings
screen.
2. Select one of the following palettes:
Rainbow
Gray
Iron

Application Operation Therm-App Operation Manual
Adjusting Emissivity
Emissivity is a characteristic of the material being observed. Emissivity is
the ability of the material surface to emit energy by radiation. The
emissivity value (0 – 1) represents the ratio of energy radiated by the
material being observed to the energy radiated by a black body at the
same temperature.
To adjust the emissivity:
1. Tap the Emissivity option on the Therm-App Settings screen.
2. Scroll to the correct emissivity ratio and tap the Set button.
Adjusting the Reflected Temperature
Reflected temperature represents the energy emitted by the surrounding
objects and reflected by the measured surface.
To adjust the reflected temperature:
1. Tap the Reflected Temperature option on the Therm-App Settings
screen.
2. Scroll to the correct temperature and tap the Set button.
Adjusting the Temperature 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) require to impact the
temperature span calculation. This setting prevents a small number of pixels
to reduce the temperature measuring resolution.
To adjust the truncation scale:
1. Tap the Temperature Truncation option on the Therm-App Settings
screen.
2. Scroll to the correct temperature and tap the Set button.
