Chapter 3: Safety
3.1 Safety with testo 510i and testo 605i
⚠️ WARNING: Magnetic field!
- May be harmful to those with pacemakers.
- Keep a minimum distance of 10 cm between pacemaker and instrument.
3.2 Safety with testo 549i
⚠️ WARNING: Risk of injury caused by pressurized, hot, cold or toxic refrigerants/media!
- Only to be used by qualified staff.
- Wear protective goggles and safety gloves.
- Before applying pressure to the measuring instrument: always fix the instrument tightly onto the pressure connection.
- Comply with the permissible measuring range (0 to 60 bar). Pay particular attention to this in systems with R744 refrigerant, since these are frequently operated with higher pressures!
- Use with A2L refrigerants
Testo measuring instruments (as of July 2020) can be used in compliance with the prescribed laws, standards, directives, and safety regulations for refrigeration systems and refrigerants, as well as regulations of the manufacturers of refrigerants of safety group A2L as per ISO 817. Regional standardization and interpretation must always be observed. For example, DIN EN 378-Part 1-4 applies to the scope of the EN standards.
During maintenance work, the employer must ensure that a hazardous explosive atmosphere is prevented (see also TRBS1112, TRBS2152 VDMA 24020-3). A hazardous and potentially explosive atmosphere must be anticipated during maintenance and repair work on refrigeration systems with flammable refrigerants (e.g., those of category A2L and A3). Maintenance, repairs, removal of refrigerants, and commissioning of systems may only be carried out by qualified personnel.
3.3 Safety with testo 805i
⚠️ CAUTION: Laser radiation! Class 2 laser.
- Do not look into the laser beam!
Chapter 4: Operation Principle
4.1 App Operation Principle
The App installed on a smartphone receives and displays measurement values from Smart probes when connected via Bluetooth. Users can also configure units or other parameters through the App.
4.2 testo 405i Operation Principle
The testo 405i features an NTC sensor that changes resistance based on ambient temperature. The circuit detects this resistance and calculates ambient temperature via the MCU. The MCU then controls the Bluetooth module to send data to the smartphone and receive parameter changes and action protocols. A key is used for start, stop, and hold functions. The LED indicates device status: Red for warnings (e.g., low battery), Yellow for finding the App via Bluetooth, and Green for successful communication.
4.3 testo 410i Operation Principle
The testo 410i uses a vane to measure flow velocity based on its rotation speed. The analog signal from the vane is converted to a digital signal for the MCU. The MCU then controls the Bluetooth module to send data to the smartphone and receive parameter changes and action protocols. A key is used for start, stop, and hold functions. The LED indicates device status: Red for warnings (e.g., low battery), Yellow for finding the App via Bluetooth, and Green for successful communication.
4.4 testo 510i Operation Principle
The testo 510i has a differential pressure sensor that detects pressure signals from gas pipes. The sensor converts pressure signals to electronic signals and then to digital signals for the MCU via A/D conversion. The MCU controls the Bluetooth module to send data to the smartphone and receive parameter changes and action protocols. A key is used for start, stop, and hold functions. The LED indicates device status: Red for warnings (e.g., low battery), Yellow for finding the App via Bluetooth, and Green for successful communication.
4.5 testo 549i Operation Principle
The testo 549i has a high-pressure sensor that detects high pressure from gas pipes. The sensor converts pressure signals to electronic signals and then to digital signals for the MCU via A/D conversion. The MCU controls the Bluetooth module to send data to the smartphone and receive parameter changes and action protocols. A key is used for start, stop, and hold functions. The LED indicates device status: Red for warnings (e.g., low battery), Yellow for finding the App via Bluetooth, and Green for successful communication.
4.6 testo 605i Operation Principle
The testo 605i features temperature and humidity sensors that detect ambient temperature and humidity. The sensors convert these signals to electronic signals and then to digital signals for the MCU via A/D conversion. The MCU controls the Bluetooth module to send data to the smartphone and receive parameter changes and action protocols.
4.7 testo 115i Operation Principle
The testo 115i uses an NTC sensor in a clamp to measure surface temperature. The circuit detects the NTC's resistance and calculates the pipe's surface temperature. The MCU controls the Bluetooth module to send data to the smartphone and receive parameter changes and action protocols. A key is used for start, stop, and hold functions. The LED indicates device status: Red for warnings (e.g., low battery), Yellow for finding the App via Bluetooth, and Green for successful communication.
4.8 testo 905i Operation Principle
The testo 905i has a TC sensor that measures ambient temperature. The circuit detects the TC's capability and calculates ambient temperature in the air. The MCU controls the Bluetooth module to send data to the smartphone and receive parameter changes and action protocols. A key is used for start, stop, and hold functions. The LED indicates device status: Red for warnings (e.g., low battery), Yellow for finding the App via Bluetooth, and Green for successful communication.
4.9 testo 805i Operation Principle
The testo 805i has an IR sensor that measures surface temperature via IR reflection. The analog signal from the sensor is transformed into a digital signal by the ADC for the MCU. The laser turns on automatically during measurement. The MCU controls the Bluetooth module to send data to the smartphone and receive parameter changes and action protocols. A key is used for start, stop, and hold functions. The LED indicates device status: Red for warnings (e.g., low battery), Yellow for finding the App via Bluetooth, and Green for successful communication.
