Features Auto Meter's V-Drop Technology – this unique Auto Meter feature utilizes a patented process to automate the measurement of voltage drop in the charging circuit during starter engagement to ensure vehicle systems are operating at peak performance. This test occurs with minimal operator effort in the short period of time required for the engine to crank over and fire. Auto Meter’s V-Drop technology prevents the need to connect additional probes and/or disable ignition or fuel systems to engage in excessive engine crank periods. In the event that your Auto Meter tester equipped with V-Drop detects an issue, it will guide the operator through the diagnosis to identify which part of the circuit is causing the excessive voltage drop.

Unlike competitor models, Auto Meter testers only require a single technician to run a full electrical system test due to our on-board 40 amp True Load cell. This eliminates the need to apply inconsistent loads, such as headlights, fans, etc. which makes our products easier to use and more accurate.
