The latest firmware release for the MFD Touch makes the multi-function display compatible with VBOX 3iS and the 100 Hz Speed Sensor, in addition to the VBOX 3i. The 4.3” daylight readable colour touchscreen makes it easy to see the data required for your test. It also provides the driver with audio and visual alerts, including when user-defined data conditions or test conditions have been met, via an inbuilt speaker and 4 x LED status lights.
