DigiTMR S2 PC User's Manual (English)

The Vanguard DIGITMR S2 PC is an inexpensive, easy to use digital circuit breaker analyzer that is designed to be used with a PC. This inexpensive analyzer offers the most cost-effective method for testing circuit breakers. It can fully analyze a circuit-breaker’s performance by testing the contact time, stroke, velocity, over-travel, and contact wipe. Contact-motion analysis can be performed for all breaker contact operations (Open, Close, Open – Close, Close – Open, and Open – Close – Open). The DIGITMR S2 PC offers three dry-contact channels (for timing circuit breaker main and insertion resistor contacts), one digital transducer channel (to monitor CB contact motion), and two voltage monitoring channels.
  • Inexpensive, PC-controlled EHV circuit breaker analyzer
  • Optional "on-line" timing mode
  • Small and light-weight
  • Can test contact time, stroke, velocity, over-travel, and contact wipe
