3. Description and markings
3.1. Presentation
The dynafor™ HHD is a portable colour display device
which is designed to receive, process and display the
signals from one or more of the dynafor™ Pro, Expert
or Transmitter WL sensors.
The link between the two components (sensor and
dynafor™ HHD) is based on a 2.4 GHz frequency band.
The equipment is delivered in a box containing:
• The dynafor™ HHD;
• Its mains charger and a USB C to USB A cable;
• Its installation, operating and maintenance manual;
• Its CE declaration of conformity.
The technologies implemented at the levels of radio
and software offer, in addition to traditional uses
expected of a hand held device of a professional
dynamometer (load display, tare, peak load, etc.)
multiple configuration possibilities that combine one or
more sensors. They also provide access to advanced
functions such as saving, threshold management and
monitoring in real time.
The option of a PC link via a USB port opens the door
to data management and archiving.
The different possible combinations are described in
chapter 4. Equipements associés.
3.2. Operating principle
The operating principle of the dynafor™ HHD is based
on the analysis and processing of the measurement,
transmitted by radio waves from the associated sensor.
