DIGITAL CURRENT CLAMP JT2004

Jaltest Digital Current Clamp JT2004 (SKU 50002004) — $105

The Jaltest Digital Current Clamp JT2004 (part 50002004, $105) is a professional-grade clamp meter for measuring current without breaking into circuits. Part of the Jaltest Tools product line from Cojali, it pairs directly with the JT2003 multimeter and the rest of the Jaltest electrical testing toolkit. At $105, it is the practical add-on for any shop that needs to measure current draw on truck electrical systems, starter circuits, alternator output, or sensor supply lines without cutting or disconnecting wiring.

What a Digital Current Clamp Does

A current clamp meter measures amperage by clamping around a conductor and reading the magnetic field it produces — no circuit interruption required. This is the correct tool when you need to:

• Check starter motor current draw to evaluate battery and starter health on diesel engines
• Measure alternator output without disconnecting the alternator cable
• Verify sensor supply current to identify open or shorted sensors
• Diagnose parasitic draw on truck and equipment electrical systems
• Test motor current on hydraulic pump motors, cooling fans, and actuators
• Confirm proper current flow through DEF/AdBlue heater circuits

Why It Belongs in a Diesel Shop

Commercial truck electrical systems run high currents — starter circuits on diesel engines regularly pull 600-1,000+ amps, and alternators on Class 8 trucks produce 200-350A continuously. A clamp meter is the only safe way to measure these values without specialized breakout harnesses. For diagnostic work alongside Jaltest software, the JT2004 gives you the live current data at the circuit level that the ECU data stream cannot always provide.
