CHAPTER 4
Example: (V = 55,000 lb - 35,000 lb = 20,000 lb)
If the average difference between the certified scale and the meter is more than several hundred
pounds, you may want to adjust the Calibration Numbers. If so, proceed to Step 8.
To determine the new Calibration Number for each Channel refer to the formula shown below:
New Channel Cal Number = Old Channel Cal Number x (P / V).
Example: Old Channel Number = 2050
P= 21,240 lb (Certified scale
net
weight).
V = 20,000 lb (Vulcan scale
net
weight).
New Channel Number = 2050 x (21,240 / 20,000) = 2177
The Calibration Number for Channel B is the same as the Calibration Number for Channel A.
Channel B New Cal Number = Channel A New Cal Number
(Example: Channel B New Cal Number = 2177)
Record the new Cal Numbers in Section 7.4, “Keeping Records” located in the Appendix.
Repeat this procedure for other channels if they do not directly represent axle group weights.
(Example: C and D)

Enter the
SETUP / CALIBRATION
Menu, (Section 3.3).
Press the
CYCLE
