ACH4 – 400A Amp Clamp Accessory Head

Measure AC Amps up to 400A.

Jaw claw helps isolate wires for testing

Find run/start amps of motors and compressors

Great partner for stick multimeters

The ACH4 current clamp is a small size accessory head for quickly reading up to 400 AC amps. The claw feature on the clamp makes it easy to quickly pick out the wire you need to measure. Once the current carrying conductor is isolated, the amperage is converted to mVAC for reading directly on the meter. The ACH4 works with the Fieldpiece “Stick” meter, EHDL1 Electronic Handle, EH4W Wireless Handle, DL3 Data Logger, the HG2 and HG3 HVAC Guide® System Analyzers, or any other digital multimeter (with mVAC range) connected by Fieldpiece ADLS2 detachable silicone leads or AHDL1 handle adapter.

Features:

• Connect directly to any Fieldpiece stick meter (shown attached to HS36)
• Remote the amp clamp for hard to reach areas using our deluxe silicone leads with detachable probe tips (model ADLS2)
• Angled jaw opens to 1.8 inches and makes singling out a wire fast and easy
