The Vanguard DIGITMR S2 is an inexpensive, easy to use digital circuit breaker analyzer. The DIGITMR S2 can be operated stand-alone or can be computer-controlled. It can fully analyze a circuit-breaker’s performance by testing the contact time, stroke, velocity, over-travel, and contact wipe. Contact and motion analysis can be performed for all breaker contact operations (Open, Close, Open – Close, Close – Open, and Open – Close – Open). Timing results are recorded and displayed on the 240 x 128 pixels back-lit LCD screen and can also be printed on the built-in 4.5" wide thermal printer.

• Stand-alone, microcomputer-driven EHV Circuit Breaker Analyzer
• Analyzes contact time, stroke, velocity, over-travel, and contact wipe
• USB PC interface
• USB Flash drive interface
• Can store up to 200 test records and 100 test plans
• Built-in thermal printer
