    This app works on most Android devices running 5.0 or higher with a micro USB or USB-C port supporting USB-OTG (On The Go). It is easy to operate: after you plug your CT device to your phone or tablet, the app will start automatically. The device is powered by your phone. Different digital temperature values can be displayed in the temperature time diagram.

  • Page 89: Communication Settings

    8.2.2 Protocol All sensors of the CT series are using a binary protocol. Alternatively, they can be switched to an ASCII protocol (only LT versions). To get a fast communication the protocol has no additional overhead with CR, LR or ACK bytes.

  • Page 90: Ascii Protocol

    8.2.3 ASCII protocol The models LT02, LT15, LT22, LT02H and LT10H can be switched to ASCII by changing the first figure of block 3 of the head calibration code. This figure has to be changed from 0 to 4 (old sensing head) or 8 to C (new sensing head).

    8.2.4 Saving of parameter settings After power on of the CT sensor the flash mode is active. It means, changed parameter settings will be saved in the CT-internal Flash-EEPROM and will be kept also after the sensor is switched off.

    9 Basics of Infrared Thermometry Depending on the temperature each object emits a certain amount of infrared radiation. A change in the temperature of the object is accompanied by a change in the intensity of the radiation. For the measurement of “thermal radiation”...

  • Page 93: Emissivity

    Emissivity 10 Emissivity 10.1 Definition The intensity of infrared radiation, which is emitted by each body, depends on the temperature as well as on the radiation features of the surface material of the measuring object. The emissivity (ε – Epsilon) is used as a material constant factor to describe the ability of the body to emit infrared energy.

    and take the temperature of the sticker. Afterwards, determine the temperature of the adjacent area on the measuring object and adjust the emissivity according to the value of the temperature of the sticker. ► Cove a part of the surface of the measuring object with a black, flat paint with an emissivity of 0,98. Adjust the emissivity of your infrared thermometer to 0,98 and take the temperature of the colored surface.

  • Page 98: Appendix C - Smart Averaging

    Appendix C – Smart Averaging The average function is generally used to smoothen the output signal. With the adjustable parameter time this function can be optimal adjusted to the respective application. One disadvantage of the average function is that fast temperature peaks which are caused by dynamic events are subjected to the same averaging time.
