Features:

•  Chassis:Our reference designs are based on chassis in three different sizes.Nissan crew cab pickup-truck chassis;IVECO 

Daily van-type chassis;ISUZU light truck chassis.

•  Vehicle assembly:We work with professional truck builders that meet out strict quality standards.

•  Interior layout:The interior layout is thoughtfully designed.Most connectors and operation panels are conveniently located at 

one side of the vehicle.Cover panels are pneumatically raised.Spacious and well-lit interior space improves ergonomics and 

efficiency.Operation space has large windows for observation.

•  Driving safety:All vehicle designs have balanced weight distribution with low center of gravity to ensure the drivability of the 

vehicle.Cameras and sensors are placed in all directions to improve situation awareness when driving.Camera footage can be 

recorded just as dashcam.

•  Equipment and racks:All measurement instruments are designed as standardized rack-mount units.Units can be installed 

and uninstalled with ease.Common resources for testing are also integrated into removable “Common Supporting Units”.

Key features of the Common Supporting Units:

•  Power supporting unit:An integrated unit that routes, combines, and manages power from three sources: grid as main 

source, battery as auxiliary source, and vehicle generator as backup.

•  Integrated communication unit:Integrates means of communications, including wired (USB, RS232/485, Ethernet) and 

wireless (Wi-Fi, 3G, 4G).Connects compatible third party measurement instruments.

•  Safety surveillance unit:Monitors the following sub-systems or factors: power source system, testing power supply system, 

environmental conditions, grounding conditions, warning system, and measurement system conditions.Four analog and six 

digital I/O ports are reserved for more monitoring and controlling needs.
