5 Test Equipment and Tools
There is a wide variety of tools and equipment needed to safely and correctly perform airfield lighting
equipment installation and maintenance. In addition to the obvious tools (screwdrivers, wrenches, etc.),
there is a specialized equipment needed to do the job.
Multimeter
One of the most important pieces of test equipment is the Multimeter. It is used to measure voltages,
currents, and resistances. Almost every single maintenance task requires the use of a multimeter at one
point or another. A quality meter in good repair and calibration is a must because airfield lighting power
distribution equipment produces non-sinusoidal waveforms, traditional average reading meters are
inaccurate and have very limited use. Checking or adjusting equipment based upon incorrect current
reading may dramatically reduce lamp life and adversely affect power equipment performance. A meter
with TRUE RMS measuring capability and a current clamp-on probe is needed to accurately measure
distorted or chopped waveforms. All meter manufacturers offer TRUE RMS measuring meters. The
following is a short list of TRUE RMS Multimeters from Fluke:
Manufacturer Model Number
Fluke 87V, 287
Our recommended meter is the Fluke 87V with the Fluke I800 current clamp.
Refer to the equipment manufacturer’s manuals for the proper use, maintenance and calibration (if
necessary) of all meters.
