About This Product

Product Info


Fieldpiece - The ACH4 current clamp is a small size accessory head for quickly reading up to 400 AC amps. The new claw feature at the top of the clamp allows for quickly picking out the wire you need to measure and isolating it in the clamp. 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, DL3 Data Logger, the HVAC Guide® System Analyzer or any other digital multimeter (with mVAC range) connected by Fieldpiece ADLS2 detachable silicone leads or AHDL1 handle adapter.

  • 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
  • 400A Amp Clamp Accessory - ACH4
  • Operator's Manual
