The 100ADM mk4 provides commissioning and maintenance engineers with a flexible system for testing protective systems. It has an easy to understand panel layout and a simple user interface. The status of every function can be seen at a glance, and there are no complex menus to navigate.

The 100ADM mk4 keeps the familiar user interface of previous models but adds a new metering system that accurately measures the RMS of a single cycle. It also features a new current limit mode to provide very fine control of low currents, even into low impedance loads. Current limit mode also assists in testing self-powered overcurrent protection as fitted to many 11kV ring main units.




  • Clear and simple user interface.
  • Zero to 100 amps output current.
  • Current limit mode for fine current control.
  • True RMS metering with single cycle capture memory ammeter.
  • Multi-function auto-ranging timing system.
  • Auxiliary DC and AC output.
  • Large back-lit liquid crystal display (LCD).
  • Thermal and Over-current protection.
  • Automatic mains voltage selection.
  • Compact and portable with shoulder carry strap.


  The unit has a range of outputs allowing injection of currents as low as a few mA and as high as 100A. Voltages up to 240V are available allowing high impedance current relays and voltage relays to be tested. Four true RMS metering ranges are provided, and the full scale of the meter (and trip level) can be set independently of output tap. Industry standard safety connectors are used on all inputs and outputs for convenience, reliability and safety.

A very flexible two channel timing system is provided, allowing trip times, reset times and reclose times to be quickly measured to a high degree of accuracy. The timer auto-ranges to measure from 1ms to 99999.9 seconds. The outputs of the 100ADM mk4 are well protected. The main output is protected by overcurrent, duty cycle and thermal trips. The auxiliary DC supply is protected by a current limit, and the auxiliary AC supply is fuse protected.
