The Extech 380941 200A AC/DC Mini Clamp Meter fits easily into tight spaces and gives clear, stable readings. It measures AC and DC current without breaking the circuit, so work stays quick and safe. The large display shows values you can read at a glance, and the bargraph helps you see changes in real time.
Measurements and display
You can measure voltage, resistance, frequency, and continuity using the test leads, then swap to the clamp for current. A one-touch zero makes DC current setup simple, while MIN/MAX and Data Hold help you capture and keep important values. The meter feels solid in hand and the trigger makes clamping single conductors easy.
Built for safety and convenience
The clamp uses a Hall-effect sensor so DC and AC current readings are reliable. The design meets CAT III 300 V and CAT II 600 V categories, which suits many industrial and building systems. AA batteries power the unit, so replacements are easy to find in the field.
Ready for daily use
A 23 mm jaw opening handles many small to mid-size conductors in panels and machinery. The meter’s display updates quickly, and the controls are simple to understand. With a clear manual and a standard warranty, it’s a dependable tool for electrical and maintenance work.
