Introducing ATPOL II

Congratulations on your decision to buy an ATPOL II. You have just purchased one of the smallest and

yet most powerful instruments for measuring and analyzing electric power that exists.

The ATPOL II 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

If you are looking for a simple yet powerful tool that can be easily and reliably installed and operated,

one that provides for comprehensive data analysis, you've found your tool of first choice.

Whether your interest is in

The quality of incoming power,

Managing power consumption, or

Maintaining and comparing equipment

ATPOL II 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 “Volt” key is referred to as [Volt].

Connecting to ATPOL II

Voltage Test Leads

A Deluxe Voltage Probe set consisting of four leads is included with each ATPOL II. 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 VNtest lead. Optional

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 600

Vrms rating of ATPOL II. The clamps of the deluxe voltage leads are rated for 1000V working voltage,

measurement category III. This is equivalent to measurement category IV for a working voltage of

600V, the rating of the ATPOL II.

ATP 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

ATP 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 AT6001 are excellent choices to use with ATPOL II because they support all the

accuracy specifications of the product. For instance, the AT6001 has an accuracy of 0.5% whereas

many probes on the market have an accuracy of 2-3%. Also, the AT6001 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 AT6001 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.

The AT6003 offers two advantages over the AT6001, but these advantages come at a cost. Its

advantages are that the AT6003 is a very small size (5.25 2.00 1.35 inches) and second, it offers

much greater sensitivity since it reads currents from 20 milliamps to 5 amps (as compared to the

AT6001 measuring 1 - 1,000 amps). The tradeoff is accuracy. The probe has a basic accuracy of 2%

and its phase shift varies by frequency and by amplitude. All told, you can expect to measure current to

a nominal 2.25% accuracy and power and cost to a nominal 3% accuracy using the AT6003 probe.

The AT6002 probe is the same compact size as the AT6003. The AT6002 measures from 0.1 to 100

amps at 2% accuracy. It is a good choice over the AT6001 if you wish to lock ATPOL II, its leads, and

current probes inside a power panel that you are monitoring. It is also a good choice when small size is

important while measuring currents above 5 amps. The AT6002 is a popular choice for a second set of

probes.

For very large currents and large bus bars, we offer the AT6012. The AT6012 is a "flex" type probe. It

consists of a flexible tube about 0.4 inches in diameter and 24 inches long (a 36 inch version is also

available). The ends of this tube snap together around a conductor to sense the current. Flex probes

are very handy when space is tight, when multiple cables must be clamped around, or when a bus bar

is present. They are also lighter than clamp-on probes. The flexible tube creates a circle with an inside

diameter of 7 inches. This circle can be deformed into various shapes to accomplish your

measurement goals. The basic accuracy of the flex probe is good, measuring from 1 to 6000 amps

(across two ranges) within 1% accuracy. However, readings can vary as much as 2% depending on

the position of the flex probe while connected. Position the flexible portion of the probe around the

conductor so that the cable from the probe drops straight down and the place where the ends snap

together is at a right angle with the conductor and not touching it. The frequency response of flex

probes is very good, but phase shift increases with frequency. Our AT6012 is powered by the meter,

so no batteries are required.

You must use added caution when connecting an AT6012 series current probe around

exposed conductors and bus bars since you must pull the tube around the conductor and thus

get your hands and arms closer to it than when using HA series clamp-on type current probes.

Wise practice dictates that you use high insulation protection on hands and forearms in these

circumstances or deactivate the circuit.

The AT6000 probe is used for AC current measurements from 5 to 400 amps and DC measurements

from 5 to 600 amps. It offers accuracy of 2% 1 amp from 5 - 400 amps and 3% accuracy for DC from

400-600 amps. This probe relies on Hall Effect technology and its output varies slightly over time.

Therefore, a zero level adjustment is provided on the probe's handle for initial zeroing before each

measurement session. The probe can clamp around one cable up to 1.18 inch diameter or two cables

of up to 0.95" diameter. Unlike other manufacturers’ DC probes, ours do not require batteries for them

to run.

New probes and adapters are introduced regularly, so if you have a special need, give us a call.

Please Note: Always inspect the metal surfaces of clamp-on probes before use. Clean them

with a rag or sand them with fine sand paper and then slightly oil the surface. Any dirt or rust

will affect the accuracy of the measurements!

Connections to ATPOL II

Voltage test leads plug into the top end of ATPOL II. Each test lead of the Deluxe Voltage Test Lead

set is labeled (VN, V1, V2, or V3) and each jack is similarly labeled (VN, V1, V2, or V3).

Note: The VNtest lead is a different color from the other leads (black). Similarly, the VN

jack on ATPOL II is a different color from the other ones (black). Connecting anything other

than neutral or ground to the VNjack can jeopardize your safety, the functioning of the unit, and

the accuracy of the unit.

Current probes plug into the top end of ATPOL II, just above the voltage inputs. Each current probe is

labeled (I1, I2, I3, or IN) and each jack is similarly labeled (I1, I2, I3, or IN). When plugging a current

probe into ATPOL II, the flat side of the plug should be facing upwards so the label is readable. This

will align it properly for plugging into the ATPOL II case.

Clamp-on probes have a correct orientation in which to attach them. On most probes' head, there will

be an arrow pointing in the direction of the conductor being measured. When clamped onto I1, I2, I3, or

IN, the arrow should point along the conductor from the power source towards the load. If the current

probe is connected backwards, its waveform will appear upside-down when you upload waveforms, it

may be slightly less accurate in its current readings, and, most importantly, if you operate in

positive/negative power measurement mode, power readings will be disastrously wrong.
