Simulated Testing

A simulated load test consisting of at least three consecutive test runs should be conducted as soon as possible,
but not more than 12 hours after the completion of the material test, to establish the factor to relate the results of
the simulated load test to the results of the material tests. The results of the simulated load test should repeat
within 0.1 percent.

Simulated testing is used only with auto calibration of the integrator.

There are two different simulated load testing techniques that can be used. They are:

Roller test chains

Static test weights

There are several advantages and disadvantages to each of the list simulated testing techniques. They are listed
below.

Simulated Testing Type

Advantages

Disadvantages

Roller (chain)

Simulates some conveyor belt
effects

Chains do not provide a traceable
conveyor scale calibration standard.

Acceptable simulated test

Heavy chains are difficult to handle.

Conveyor belt must be stopped to
apply and remove.

Linearity test requires several chains.

Chains are costly.

Static

Simulates some conveyor belt
effects

Weights do not provide a traceable
conveyor scale calibration standard

Easy to apply

Does not simulate conveyor belt
effects

Conveyor belt does not have to be
stopped to apply

Linearity test is easy to perform

Detect load cell failures, and applies
force to the load cell

Acceptable simulated test
