INTRODUCTION

Congratulations on your purchase of Extech’s 380926 Clamp meter + Digital MultiMeter. This
meter can measure to 2000A through the clamp and also measure to 400mA through the test
leads. With Capacitance, Diode and Duty Cycle measurements, this meter provides the user
with a full featured multimeter combined with the high amperage current clamp. This meter is
shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
