Perform Portable Measurement using Wireless connection
In the portable measurement setup, the Data Recorder is undocked from the
Docking Station and the Wi-Fi Link is used for data transmission. This setup is
optimal for usage scenarios where freedom of movement is an important
requirement.
The data from the Data Recorder is sent through Wi-Fi to the Docking Station. Please
note that successful wireless data transmission can never be guaranteed, even
when the amount of data (few channels, low sampling rate) is low. If the Docking
Station does not receive a data package, this data is not transmitted again, but
considered to be lost at that moment. Lost data can be recovered using the backup
logging feature on the on-board memory (see below).
Factors that influence wireless transmission are:
•
Other wireless networks (or RF devices such as smartphones, tablets), especially
those in the same or adjacent Wi-Fi channels.
•
Electrical equipment in the vicinity of the Docking Station and or Data Recorder.
•
The line of sight between Docking Station and Data Recorder. Metals and human
beings tend to absorb or reflect a lot of wireless signals.
It is recommended to scan the environment for possible wireless interference
sources.
Pairing of Docking Station and Data Recorder
The Docking Station acts as an access point for the Data Recorder. Once docked,
the Data Recorder and Docking Station will exchange pairing codes automatically.
When you configure the device for wireless use, the connection between Docking
Station and Data Recorder is made.
Data backup logging
During a measurement via a wireless data connection, the Data Recorder will log
the measurement data on the on-board memory card as backup. Lost data can be
retrieved after the measurement has been finished. Refer to
chapter 5.6
detailed instructions on recovery of lost data.
This feature can be disabled in software. Obviously, this will result in a situation
where lost data cannot be recovered.
