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.

The back-lit display on the 100ADM mk4 is bright and

clear with a wide viewing angle. The results of a test can

be seen here as they appear on the display.

A 24-220VDC switch-mode stabilised DC supply with current limiting
is provided to power the relay under test. An isolated, separately
switched 110VAC auxiliary supply is also provided.

 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 99999.9s.

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.

The unit is supplied
with a comprehensive
lead set in a sturdy
carrying
case.

The main output has a current limit mode that gives very fine control
of output currents up to 10A. It also allows fine current control into
very low impedance loads such as digital relays.

Each contact circuit will auto-select for normally open or normally
closed contacts. A DC voltage of 24—240VDC may also be used to
trigger either timer channel. Contact state is shown by an LED. The
output automatically switches off at the end of the test to safeguard
the relay under test.

Metering

The output is metered by a digital true RMS system with a single
cycle capture memory ammeter—whenever the timer stops and the
output is switched off, the reading is held on the display. A current
trip is set to 110% of full scale of the selected metering range.
