CHAPTER 4

Calibration Procedure:
Fully load the truck close to the legal limit.
Lock the meter on the two channels being calibrated. Example: A+B.
Weigh the loaded truck using a certified platform scale. Record the weight shown on the certified
scale and the weight as shown on the V600 meter.
a)
Weight Shown on Certified Scale (truck fully loaded)
___________________________
(Example: 56,240 lb Certified Scale: truck fully loaded)
b)
Weight Shown on V600 meter (truck fully loaded for channels selected, Example:
A+B)
___________________________
(Example: 55,000 lb V600 Meter: truck fully loaded)
Dump the payload.
Weigh the empty truck on the
same
certified platform scale. Record the weight shown on the certified
scale and the weight as shown on the V600 meter for the channels selected
(Example:
A+B).
a)
Weight Shown on Certified Scale (truck empty)
___________________________
(Example: 35,000 lb Certified Scale: truck empty)
b)
Weight Shown on V600 Meter (truck empty) for channels selected (Example: A+B)
___________________________
(Example: 35,000 lb V600 Meter: truck empty)
Calculate the
Net weights
(P and V) from both the Certified Scale Readings (P) and the V600 meter
readings (V). This is done by subtracting the empty weight from the fully loaded weight.
P = Weight shown on Certified Scale (truck fully loaded) - Weight shown on Certified Scale
(truck
empty)
Example: (P = 56,240 lb - 35,000 lb = 21,240 lb)
V = Weight shown on V600 meter (truck fully loaded) - Weight shown on V600 meter (truck
empty).
