Rice Lake TradeRoute HL Series - Calibration Techniques - Manual (Page 3)

Over-Strapping Method
Some tank applications are best calibrated using test weights hung from heavy strapping material. In these cases, it
is critically important that straps be placed along the vertical seams of the tank where they can be supported by the
seam.
CAUTION
DO NOT place straps or other load bearing supports on tanks without first ensuring that there is not a risk
of damage to the tank structure.
Shallow Pit Method
Using a shallow pit to contain test weights and a heavy grating over the pit to allow for truck axles loads, it is
possible to suspend test weights from the scale to achieve scale calibration. This technique is reliable and safe. It is
a permanent solution for trucks that must be re-tested every year.
Calibrating with Load and a Truck Scale
Check first with local authorities to make sure this technique is allowed. Using a truck scale to calibrate a
TradeRoute is a simple, fast and safe method for completing a TradeRoute calibration.
