Overview

The MTM and TTM test meters were originally designed for use with the Bombardier EBI Track 300 and EBI Track 200 track circuits. With the development of the EBI Track 400 track circuit the meters were intended to be used until a dedicated test meter has been developed.

Due to the inherent design of the test meters, when used with EBI Track 400 the MTM and TTM accuracy is degraded and measurements can exhibit an accuracy tolerance of greater than 10%.

This Additional Operating Instruction sheet has been created to aid the user in taking as accurate as possible measurements when using the MTM or TTM on EBI Track 400 track circuits.
