1. OTHER EUROSMC PRODUCTS cccccccsccccccccscecees GO Operation Manual Introduction The PME 500 TR circuit breaker analyzer has been designed to simplity tests of contact synchronism coil current analysis and contact resistance measurement on medium voltage circuit breakers or in any case on circuit breakers with a single contact per pole Its use for circuit breakers with multiple contacts per pole is not advised although this might occasionally be done by means of a more laborious process The use of the touch screen panel makes operation of the unit and data entry processes easier and more intuitive The multi pole connecting blocks have been duplicated with standard banana type connectors in case any of the multi wire test leads are accidentally damaged lost or made unavailable in any way The internal battery supply makes the equipment independent trom the low voltage AC supply not always available or close enough to the place of operation The contact resistance measurement is performed on the three poles at a time using the four wire method and with an outstanding resolution of 0 1 micro ohms under a measurement current of 10 A Please read this operation manual before using the PME 500 TR for the first time The support team at EuroSMC will be very pleased to answer your questions if any arise Congratulations for your good choice and thank you tor considering EuroSMC products and services EUROSMC S A2.
