CALCULATION OF SPEED CAL FOR ALL CONSOLES (EXCEPT SCS 400)
The switches and keys referred to below are on the Raven SCS Console. Use steps 1 and 2 if
Console has SP1/SP2 select.
NOTE:
Numbers in brackets [ ] are metric equivalents.
1)
Reset console according to the instruction manual.
2)
Complete INITIAL CONSOLE PROGRAMMING, in the Installation and Service
Manual for your console. Select SP2 for correct operation of radar. If your console
does not have SP1/SP2 select, you must either update your console’s program or
use a radar adapter (P/N 063-0159-590).
3)
For all consoles except SCS 500/550, enter a SPEED CAL number of 598 [152] in
key labelled
. For SCS 500/550 console, enter a SPEED CAL number of 299
[76] in key labelled .
4)
Set POWER switches to ON, all other switches to OFF.
5)
Enter “0” in key labelled
.
6)
Drive 1 mile [1 kilometer]. To achieve the most accurate calibration, accelerate and
decelerate slowly.
CAUTION:
Do not use vehicle odometer to determine distance. Use section
lines or highway markers.
7)
Read DISTANCE by depressing key labelled .
DISTANCE display should read a value of approximately 5280 [1000]. If it reads
between 5260-5300 [990-1010], the SPEED CAL is 598 [152].
If the DISTANCE display reads any other value, divide SPEED CAL by the value
observed in DISTANCE, then multiply by 5280 [1000]. This will give you the correct
value to enter for SPEED CAL. Round off to the nearest 3 digit number.
EXAMPLE:
Assume DISTANCE reads 5000 [980].
ENGLISH UNITS:
METRIC UNITS:
598 x 5280 = 631.48
[152] x [1000] = [155]
5000
[980]
The number to enter for SPEED CAL is 631 [155].
8)
Recheck the new SPEED CAL calculated in Step 7 as follows:
a)
Enter the new SPEED CAL number as in Step 3.
