Safety Notices
This equipment is normally used or connected to circuits that may employ voltages that are
dangerous and may be fatal if accidentally contacted by operating or maintenance personnel.
Extreme caution should be exercised when working with this equipment. While practical safety
precautions have been incorporated in this equipment, the following rules must be strictly
observed:
5.1
Keep Away from Live Circuits
Operating and maintenance personnel must at all times observe all safety regulations. Do not
perform maintenance on internal components or re-lamp with power ON.
5.2
Resuscitation
Maintenance personnel should familiarize themselves with the technique for resuscitation found
in widely published manuals of first aid instructions.

Recommended 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 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
with a current clamp-on accessory 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:
