Part of Yokogawa’s 255 Series, it accepts direct voltage input and reports 0–40 volts via a precision analog needle on a panel-mounted, industrial-grade housing. Commonly installed in automotive test benches, generator testing equipment, and maintenance diagnostic panels, this meter is used by maintenance teams and system integrators to test alternator performance, diagnose charging-system issues, or replace failed testers in legacy installations. In automotive and industrial testing environments, it provides real-time visual indication of voltage output and charging performance, supporting proper operation as alternators charge batteries. Common replacements include Yokogawa 255-400-EAEA and Yokogawa 254320PKPK8.\u003c\/p\u003e\u003c\/div\u003e","brand":"Yokogawa","offers":[{"title":"New","offer_id":46241931493610,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-001.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/yokogawa-255400eaea8jey-alternator-tester-panel-meter","provider":"GTG Hardware","version":"1.0","type":"link"}
