Using VBOXTools software, logging of the analogue channel data can be switched on or off. It is also
possible to change the name of each input channel and configure scale and offset values for calibration
of sensors.
A scale value of 1 and offset of 0 correspond to a channel reading in Volts DC. This means that the
value stored on the compact flash card for the channel will also be in volts. When using a sensor such
as a load cell, it may be desirable to store a reading in Kg. In this case, changing the scale and offset to
suit the sensor data sheet allows the data stored onto the compact flash to be in Kg. When changing
channel setup for an analogue channel using VBOX Tools software, a live data view of the current
channel is shown. The value shown is the value after scale and offset is applied and can therefore be
used to aid sensor calibration.
500Hz logging
VB3i has the ability to log 4x analogue channels at 500Hz. With this feature enable the file sizes will
increase as a result.
When loading the VBO file into VBOX Tools ensure you are running the very latest version as older
versions are not compatible with 500Hz data.
