  • measuring electric current, e.g. at the time of starting or while the engine or compressor is running;
  • in connection with the meter, translating the result obtained in ACC to mVAC.


Fieldpiece ACH4 is a cover for the meter (or for AHDL1 - a handle with meter leads) having the form of clamps, designed for quick measurement of alternating current of up to 400 amperes. The refined shape of the ammeter jaws allows you to efficiently isolate the test cable. The current flowing through the gripped wire is transferred from amperes to mVAC units (in a ratio of 1ACC to 1mVAC), whose value is displayed by the connected meter, set to the range of millivolts of alternating current.

The ACH4 head works with the full range of Fieldpiece tools:
  • with electronic "stick" gauges (connecting the head to the latch), e.g. HS35;
  • with the EHDL1 electronic handle;
  • with the DL3 data logger;
  • with the HG3 refrigeration system analyzer;
  • with any other digital multimeter working on mVAC values, connected via AHDL1 handle or ADLS2 cables.
  • Advantages:
  • thanks to the modular design, the ammeter can work in conjunction with any Fieldpiece tools, and with other devices using jack plugs (in the AHDL1 holder);
  • the small size of the jaws makes it possible to reach wires located in a limited space;
  • giving one of the jaws a spike shape helps to separate a given cable from a group of others;
  • wide jaw spacing (4.6 cm) facilitates the insulation of larger diameter wires;
  • embossing on the clamps suggests how to center the tested cable optimally in order to obtain an absolutely accurate result;
  • the design of the clamps, physically separate from the electronic devices cooperating with them, guarantees that they will not affect the measurement result.
