Electrical parameters:
Working voltage: 5V or 12V
Test range: 2-400CM
Output mode: two switch output, output control relay
Keys to adjust the distance: according to the buttons to adjust the distance, in the appropriate range of the output alarm
Press key usage method:
1, long press the S3 key for 3 seconds or so, showing the emergence of LLL.
2, then press the S3 key, the display appears a number (default 100CM), for the minimum measurement limit, the minimum measurement limit can be increased by S1, S2 reduced to change.
3, when setting the minimum measurement, then click the S3 button, showing the emergence of HHH, for the maimum measurement limit set; and then press the SET button, showing a number (default 255CM), for the maimum measurement limit value. Maimum measurement limit. By increasing the S1, the S2 decreases to change.
When setting the maimum value, then press the S3 key, save the set value, and has the power down storage function.
