Y = measured distance X = DCR Reading
A = Multiplier B = Offset
The multiplier (A) can be determined by taking ultrasonic readings at two
known distances and dividing the difference of the known distances (D) by the
difference of the ultrasonic (U) readings (A) = (D
2
-D

)/ (U

-U

) where;
D

= far known distance U

= Ultrasonic reading at D

Enter this multiplier in Modes 47 and 48. The multiplier can then be entered
in the above equation to calculate the offset B = D

. The offset should
be entered using Modes 45 and 46.
Utilities
Reset
When the DCR is powered up, ‘NO’ is loaded in mode 49. This saves the
user-selected modes into the DCR. If the mode adjustments get scrambled or if
the factory preset values are wanted, press the NUM UP key. If ‘YES’ is
entered, the DCR will perform a reset, loading all the modes with the default
parameters.
MODE DESCRIPTION PARAMETERS EXPLANATION
49 Reset Range = no - yes Reset the mode parameters to
Default = no their factory preset values

Set by NUM UP or NUM DN
Software Version
Mode 50 displays the software version for the DCR. The value corresponds
to the operating version and the approximate date of manufacture.
