ST181 4000-count clamp meter & XL830L 2000-count multimeter electrical system tool

Complete electrical testing kit

This kit combines a 4000-count clamp meter and a 2000-count digital multimeter for comprehensive electrical diagnostics. The clamp meter measures AC current up to 400A without breaking circuits, while the multimeter provides precise DC current and voltage readings. Both instruments feature large backlit LCDs for visibility in dark environments. The set suits automotive, household outlet, and industrial troubleshooting tasks.

Upgrade from single-function testers

Technicians relying on basic voltage pens or single-range meters gain simultaneous clamp and probe capabilities in one purchase. The jump is worth it when you need non-contact voltage detection, 1.42-inch double-open jaws for large conductors, and measurements spanning capacitance, frequency, and diode test. The kit replaces carrying separate tools for AC clamp and DC probe work.

Limits of the 4000-count and 2000-count displays

Resolution tops out at 0.01A for clamp current and 100µV for multimeter DC voltage, so fine parasitic-draw analysis may need higher-count instruments. AC voltage accuracy is specified at ±(1% + 5) on the clamp meter and ±(2.0% + 10) on the multimeter, limiting precision on noisy mains. The 400A AC clamp range and 10A DC probe ceiling define the maximum measurable currents without external shunts.
