Wireless RF PTP® TX & RX:

Bluetooth™: is a transmitting standard for wireless connections. Bluetooth™ devices can take up contact completely independently and automatically with one another. The communicating devices change thereby repeatedly per second the frequency channel (frequency hopping) with a jump width of 1 MHz within the ISM range 2402-2480 MHz. The frequency jump procedure ensures a particularly safe transmission, since breakdown influence (Noise, Fading, spurious distortion signals, etc.) are avoided. The protocol, with which Bluetooth™ devices inform themselves with one another, contain further information (e.g. an ID) beside the data which they communicate. Pairing makes a safe communication between two Bluetooth™ devices possible. The connection between two or several paired Bluetooth™ devices is established as soon as an device comes into the range of another equipment. The Bluetooth™ radio devices integrated for data communication in the measuring system PTP® realize internally an asynchronous serial (point to point) connection and work in this connection like a direct cable connection. The software for the Bluetooth™ devices was factory-installed.

 

Because of pairing the PTP® RX and PTP® TX both devices are to be sent to the local service in the case that a calibration of the measuring system is needed.

 

RF-exposure Statement for the Bluetooth™ RF-Modules:

This device complies with Part 15 of the FCC Rules.

The FCC ID has to be readable on the device.

Pollution Degree 2 (Normally only dry pollution, but with temporary conductivity caused by condensation)

NOTE:Tests have shown that because of the sensitive nature of the measurement and logic circuits, the following precautions must be observed:

Minimize exposure to ESD Events. If the PTP® VP-8 or one of the thermocouples receives an 8kV electrostatic discharge during the data collection sequence, the PTP® VP-8 may switch itself “OFF”. To retrieve the data, simply upload the data that was recorded prior to the event. If a new data collection sequence is started without uploading first, the existing data stored in the PTP® VP-8 will be lost.

Keep strong electromagnetic fields away. The thermocouple wires serve as an antenna for electromagnetic radiation. If field strength of 3 volts per meter is present (usually due to close proximity of radio transmitters) while the PTP® VP-8 is collecting data, the accuracy of the data may be compromised. This interference is compounded by using long thermocouple wires, as well as the effect of the thermocouple wires acting as a “tuned” antenna.
