Simultaneous measurement of luminous intensity and deviation from optical axis. The advanced configulation optical system is used, and the characteristic of light distribution for headlight under test can be shown in the screen. It is easy to be observed and adjusted. MAIN SPECIFICATIONS Luminous intensity: 0～40000cd / 0～80000cd Deviation from the optical axis: Vertical direction: up1o30?～down2o30? up25cm/10m～ down40cm/10m Horizontal direction: left2o30?～right2o30? Left40cm/10m～ right40cm/10m Luminous intensity indication error: ±10 ％ Deviation error from the optical axis: ±15， Central height indication range from the headlight tester: 460～1300mm Measuring range: 1m Length of the rail: 4.5m Ambient temperature: 5～40°C Relative humidity: 20%～90% Power: DC6V (4pcs. Of battery) Dimension: 710mm?1250mm?550mm Weight: Tester:60Kg
