The PS4550 is a complete solution for the measurement and
analysis of all aspects of power:
 High-speed transient analysis
 Swell/Dip analysis
 Harmonics analysis
 Demand analysis
 Data logging
 Automated report writing
 Wiring and system analysis
The philosophy of the product is still the same, to give you an
instrument that answers your questions about electric power in a
truly convenient size at an attractive price, now with more
features!
Whether your interest is in
 The quality of incoming power,
 Managing power consumption, or
 Maintaining and comparing equipment
PowerSight puts all the power in the palm of your hand!
*Note: Throughout this manual, whenever we refer to an individual
key of the keypad, we print the name on the key enclosed by
square brackets. For example, the “Voltage” key is referred to as
[Voltage].

Connecting to PowerSight
Voltage Test Leads
A Deluxe Voltage Probe set consisting of four leads is included
with each PowerSight. Each of the voltage test leads is 6 feet (2
meters) long, with safety banana jacks at one end and safety
plunger clamps at the other end. Each is labeled at both ends as
the V1, V2, V3, or VN test lead. The safety plunger clamps have
telescoping jaws that you can actuate while keeping your fingers
three inches away from the actual metallic contact. Regular test
probes have conventional alligator jaw attachments that require
your fingers to be within one inch of the metallic contact. Also, the
method of attaching alligator jaws to a test lead can allow a gap in
the insulation between the lead and where they join. This is
where your thumb and finger are pressing while you actuate it.
For these reasons, to avoid unnecessary risk of shock,
regular voltage test leads should not be connected to or
disconnected from live circuits and should definitely not be
connected to or disconnected from voltages above 120 Vrms.
Another word of caution: Whenever connecting to a live
circuit, remember that the jaws of a voltage test lead are
much wider when they are open than when they are closed.
The potential to short or flash across two adjacent terminals
or wires is a constant danger when connecting to a live
circuit. Depending on the current capacity of the circuit
being shorted, arc flash and a deadly explosion of molten
material can result!
Once they are securely connected, the deluxe voltage leads are
safe for steady voltages of the 1000 Vrms rating of PowerSight.
The clamps of the deluxe voltage leads are rated for 1000V
working voltage, measurement category III. This is equivalent to
measurement category III for a working voltage of 1000V, the
rating of the PS4550.

Summit Technology also sells a fused voltage lead set (order
DFV). The safety advantage of fused leads is that if a short
occurs through the insulation of a lead to ground, the fuse in the
handle should quickly blow out, preventing the lead from
vaporizing in an explosion of molten metal. The safety
disadvantage of fused leads occurs when the fuse is blown or is
removed. The user will measure 0 volts on a live circuit and may
be tempted to lower his safety awareness, possibly resulting in
shock or damage. The DFV probes are rated for 1000V,
measurement category III.
Current Probes
Summit Technology provides a variety of probes for your use.
They offer different measurement ranges, different sizes and
physical characteristics, and the ability to measure different types
of current.
Probes such as the HA1000 are excellent choices to use with
PowerSight because they support all the accuracy specifications
of the product. For instance, the HA1000 has an accuracy of
0.5% whereas many probes on the market have an accuracy of 2-
3%. Also, the HA1000 maintains its accuracy for frequencies up
to 20,000 Hz. With our spectrum analyzer option (order FAO) it
can be used to measure frequencies up to 100,000 Hz riding on
the power line. This allows accurate current and power readings
of distorted waveforms, accurate readings of harmonics, and the
measurement of current transients that other probes would not
even detect.
Phase shift is also an important probe characteristic. The HA1000
has less than 1/2 degree of phase shift across the frequency
range when measuring currents above 50 amps and just 1.5
degrees at 5 amps. This means that instantaneous
measurements of power are highly accurate, regardless of the
waveform shape. The phase shift characteristics of most other
probes on the market are not this good. This results in erroneous
power and cost measurements and distorted waveforms. Please
Note: To diminish phase shift when measuring small currents, it is
advisable to clamp onto multiple "turns" of the same conductor in
order to increase the effective current being sensed.
