Infrared Laser Distance Sensor (50m/80m) SEN0366

hi, Recently procured the SEN0366 (distance sensor) 

it was working fine out of the box, i was trying to reduce the MeaInterval time with following command
 

first i set it to 1 second as shown in manual by changing this Time interval(1S): FA 04 05 01 FC

i can set it to 5 second as well but now the issue is not able to reduce less then 1 second i.e. what mentioned in manual about sample rate 0.05 to 1 second

i need to use this in continues mode only with following command : 80 06 03 77

plz help, or is there any way to reset to factory data

regards
