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.
The modular design of the ACH4 gives it a distinct advantage over other ammeters in the field. Remoting the amp clamp with the detachable test leads allows you to measure amps with the blower door closed. You get more accurate amp draw readings with the door closed, because the system is sealed and running under normal conditions.
How Does It Work?
The ACH4 is a very accurate current clamp that slides easily on the top of our modular stick DMMs and instruments, electronic handles, and connects to other DMMs using detachable test leads (model ADLS2). It converts 1AAC to 1mVAC on your meter. In other words, when you're measuring 8.5 AAC your display will read 8.5 on the mVAC range on your meter. Isolate the wire you want to measure amperage on quickly using the wire grabbing jaw. While the clamp is very accurate, there is a prime location for the most accurate reading possible.
