TEST STATION
Location
Select an area away from the main stream of activity which employees do not walk
through in performing their normal duties. If this is not practical because of production
line flow, then the area should be roped off and marked for HIGH VOLTAGE
TESTING. No employees other than the test operators should be allowed inside.

SAFETY
4
If benches are placed back-to-back, be especially careful about the use of the bench
opposite the test station. Signs should be posted: “DANGER –HIGH VOLTAGE
TEST IN PROGRESS –UNAUTHORIZED PERSONNEL KEEP AWAY.”
Power
Dielectric Voltage-Withstand Test Equipment must be connected to a good ground. Be
certain that the power wiring to the test bench is properly polarized and that the proper
low resistance bonding to ground is in place.
Power to the test station should be arranged so that it can be shut off by one prominently
marked switch located at the entrance to the test area. In the event of an emergency,
anyone can cut off the power before entering the test area to offer assistance.
Work Area
Perform the tests on a nonconducting table or workbench, if possible.
There should not be any metal in the work area between the operator and the location
where products being tested will be positioned.
Position the tester so the operator does not have to reach over the product under test to
activate or adjust the tester. If the product or component being tested is small, it may be
possible to construct guards or an enclosure around the device to be tested. Construct the
guards of a non-conducting material such as clear acrylic, so that the item being tested is
within the guards or enclosure during the test. If possible, the guards or enclosure should
also contain safety switches that will not allow the tester to operate unless the guards are
in place or the enclosure closed.
Keep the area clean and uncluttered. All test equipment and test leads not absolutely
necessary for the test should be removed from the test bench and put away. It should be
clear to both the operator and to any observers which product is being tested, and which
ones are waiting to be tested or have already been tested.
Do not perform Hipot tests in a combustible atmosphere or in any area where combustible
materials are present.
TEST OPERATOR QUALIFICATIONS
This instrument generates voltages and currents that can cause harmful or fatal electric
shock and must only be operated by a skilled worker trained in its use.
The operator should understand the electrical fundamentals of voltage, current, and
resistance.
Safety Procedures
Operators should be thoroughly trained to follow these and all other applicable safety rules
and procedures before they begin a test. Defeating any safety system should be treated as
a serious offense and should result in severe penalties, such as removal from the Hipot

testing job. Allowing unauthorized personnel in the area during a test should also be dealt
with as a serious offense.
Dress
Operators should not wear jewelry, which could accidentally complete a circuit.
Medical Restrictions
This instrument should not be operated by personnel with heart ailments or devices such
as pacemakers.
TEST PROCEDURES
!NEVER PERFORM A HIPOT TEST ON ENERGIZED CIRCUITRY OR
EQUIPMENT!
If the instrument has an external safety ground connection be sure that this is connected.
Always connect the return lead first, regardless of whether the item under test is a sample
of insulating material, a component tested with the high voltage test lead, or a cord-
connected device with a two or three prong plug. The return lead should be connected
first for any type of hipot testing.
Plug in the high voltage test lead only when it is being used. Handle its clip only by the
insulator---never touch the clip directly. Be certain that the operator has control over any
remote test switches connected to the Hipot. Double-check the return and high voltage
connections to be certain that they are proper and secure.
NEVER TOUCH THE ITEM UNDER TEST OR ANYTHING
CONNECTED TO IT WHILE HIGH VOLTAGE IS PRESENT
DURING THE HIPOT TEST.
When testing with DC, always discharge the capacitance of the item under test and
anything the high voltage may have contacted–such as test fixtures–before handling it or
disconnecting the test leads.
HOT STICK probes can be used to discharge any capacitance in the item under test as a
further safety precaution. A hot stick is a nonconducting rod about two feet long with a
metal probe at the end that is connected to a wire. To discharge the device under test,
two hot sticks are required. First, connect both probe wires to a good earth ground.
Then touch one probe tip to the same place that the return lead was connected. While
holding the first probe in place, touch the second probe tip to the same place where the
high voltage lead was connected.

KEY SAFETY POINTS TO REMEMBER:
•Keep unqualified and unauthorized personnel away from the test area.
•Arrange the test station in a safe and orderly manner.
•Never touch the product or connections during a test.
•In case of any problem, turn off the high voltage first.
•Properly discharge any item tested with DC before touching connections.

GLOSSARY OF TERMS
(as used in this manual)
Alternating Current, AC: Current which reverses direction on a regular basis, commonly in the
U.S.A. 60 times per second, in other countries 50 times per second.
Breakdown: The failure of insulation to effectively prevent the flow of current, sometimes evident by
arcing. If voltage is gradually raised, breakdown will begin suddenly at a certain voltage level. Current
flow is not directly proportional to voltage. Once breakdown current has flown, especiallyfor a period of
time, a repeated application of voltage will often show breakdown beginning at a lower voltage than
initially.
Conductive: Having a volume resistivity of no more than 103ohm-cm or a surface resistivity of no
more than 105ohms per square.
Conductor: A solid or liquid material which has the ability to let current pass through it, and which
has a volume resistivity of no more than 103ohm-cm.
Current: The movement of electrons through a conductor. Current is measured in amperes,
milliamperes, microamperes, nanoamperes, or picoamperes. Symbol = I
Dielectric: An insulating material which is positioned between two conductive materials in such a way
that a charge or voltage mayappear across the two conductive materials.
Direct Current, DC: Current which flows in one direction only. The source of direct current is said
to be polarized and has one terminal which is always at a higher potential than the other.
Hipot Tester: Common term for dielectric-withstand test equipment.
Hypot®: Registered trademark of Associated Research, Inc., for its dielectric-withstand test equipment.
Insulation: Gas, liquid or solid material which has a volume resistivity of at least 1012 ohm-cm and is
used for the purpose of resisting current flow between conductors.
Insulation Resistance Tester: An instrument or a function of an instrument capable of measuring
resistance’s in excess of 200 megohms. Usually employs a higher voltage power supply than used in
ohmmeters measuring up to 200 megohms.
Leakage: AC or DC current flow through insulation and over its surfaces, and AC current flow
through a capacitance. Current flow is directly proportional to voltage. The insulation and/or capacitance
is thought of as a constant impedance, unless breakdown occurs.
Resistance: That property of a substance which impedes current and results in the dissipation of power
in the form of heat. The practical unit of resistance is the ohm. Symbol = R
Trip Point: The minimum current flow required to cause an indication of unacceptable performance
during a dielectric voltage-withstand test.
Voltage: Electrical pressure, the force which causes current through an electrical conductor.

INTRODUCTION
The importance of testing... User safety
In an era of soaring liability costs, original manufacturers of electrical and electronic
products must make sure every item is as safe as possible. All products must be designed
and built to prevent electric shock, even when users abuse the equipment or by-pass built
in safety features.
To meet recognized safety standards, one common test is the “dielectric voltage-withstand
test”. Safety agencies which require compliance safety testing at both the initial product
design stage and for routine production line testing include: Underwriters Laboratories,
Inc. (UL), the Canadian Standards Association (CSA), the International Electrotechnical
Commission (IEC), the British Standards Institution (BSI), the Association of German
Electrical Engineers (VDE), the Japanese Standards Association (JSI). These same
agencies may also require that an insulation resistance test and high current ground bond
test be performed.
The Dielectric Withstand (Hipot) Test....
The principle behind a dielectric voltage –withstand test is simple. If a product will
function when exposed to extremely adverse conditions, it can be assumed that the
product will function in normal operating circumstances.
The most common applications of the dielectric-withstand test are:
•Design (performance) Testing.... determining design adequacy to meet service
conditions.
•Production Line Testing.... detecting defects in material or workmanship during
processing.
•Acceptance Testing.... proving minimum insulation requirements of purchased parts.
•Repair Service Testing.... determine reliability and safety of equipment repairs.
The specific technique varies with each product, but basically, during a dielectric voltage –
withstand test, an electrical device is exposed to a voltage significantly higher than it
normally encounters. The high voltage is continued for a given period of time.
If, during the time the component is tested, stray current flow remains within specified
limits, the device is assumed to be safe under normal conditions. The basic product design
and use of the insulating material will protect the user against electrical shock.
The equipment used for this test, a dielectric-withstand tester, is often called a “hipot”(for
high potentialtester). The “rule of thumb”for testing is to subject the product to twice its
normal operating voltage, plus 1,000 volts.

INTRODUCTION
9
However, specific products may be tested at much higher voltages than 2X operating
voltages + 1,000 volts. For example, a product designed to operate in the range between
100 to 240 volts, can be tested between 1,000 to 4,000 volts or higher. Most “double
insulated”products are tested at voltages much higher than the “rule of thumb”.
Testing during development and prototype stages is more stringent than production run
tests because the basic design of the product is being evaluated. Design tests usually are
performed on only a few samples of the product. Production tests are performed on each
and every item as it comes off the production line.
The hipot tester must also maintain an output voltage between 100% and 120% of
specification. The output voltage of the hipot must have a sinusoidal waveform with a
frequency between 40 to 70 Hz and has a peak waveform value that is not less than 1.3
and not more than 1.5 times the root-mean-square value.
Advantages and Disadvantages of AC Testing and DC Testing....
Please check with the Compliance Agency you are working with to see which of the two
type of voltages you are authorized to use. In some cases a Compliance Agency will
allow either AC or DC testing to be done. However in other cases the Compliance
Agency only allows for an AC test. If you are unsure which specification you must
comply with please contact our CUSTOMER SUPPORT GROUP at 1-800-858-TEST
(8378).
Many safety agency specifications allow either AC or DC voltages to be used during the
hipot test. When this is the case the manufacturer must make the decision on which type
of voltage to utilize. In order to do this it is important to understand the advantages and
the disadvantages of both AC and DC testing.
AC testing characteristics
Most items that are hipot tested have some amount of distributed capacitance. An AC
voltage cannot charge this capacitance so it continually reads the reactive current that
flows when AC is applied to a capacitive load.
AC testing advantages
1. AC testing is generally much more accepted by safety agencies than DC testing. The
main reason for this is that most items being hipot tested will operate at AC voltages and
AC hipot testing offers the advantage of stressing the insulation alternately in both
polarities which more closely simulates stresses the product will see in real use.
2. Since AC testing cannot charge a capacitive load the current reading remains consistent
from initial application of the voltage to the end of the test. Therefore, there is no need to
gradually bring up the voltage since there is no stabilization required to monitor the

INTRODUCTION
10
current reading. This means that unless the product is sensitive to a sudden application of
voltage the operator can immediately apply full voltage and read current without any wait
time.
3. Another advantage of AC testing is that since AC voltage cannot charge a load there is
no need to discharge the item under test after the test.
AC testing disadvantages
1. A key disadvantage of AC testing surfaces when testing capacitive products. Again,
since AC cannot charge the item under test, reactive current is constantly flowing. In
many cases the reactive component of the current can be much greater than the real
component due to actualleakage. This can make it very difficult to detect products that
have excessively high leakage current.
2. Another disadvantage of AC testing is that the hipot has to have the capability of
supplying reactive and leakage current continuously. This may require a current output
that is actually much higher than is really required to monitor leakage current and in most
cases is usually much higher than would be needed with DC testing. This can present
increased safety risks as operators are exposed to higher currents.
DC testing characteristics
During DC hipot testing the item under test is charged. The same test item capacitance
that causes reactive current in AC testing results in initial charging current which
exponentially drops to zero in DC testing.
DC testing advantages
1. Once the item under test is fully charged the only current flowing is true leakage
current. This allows a DC hipot tester to clearly display only the true leakage of the
product under test.
2. The other advantage to DC testing is that since the charging current only needs to be
applied momentarily the output power requirements of the DC hipot tester can typically be
much less than what would be required in an AC tester to test the same product.
DC testing disadvantages
1. Unless the item being tested has virtually no capacitance it is necessary to raise the
voltage gradually from zero to the full test voltage. The more capacitive the item the
more slowly the voltage must be raised. This is important since most DC hipots have
failure shut off circuitry which will indicate failure almost immediately if the total current
reaches the leakage threshold during the initial charging of the product under test.

INTRODUCTION
11
2. Since a DC hipot does charge the item under test it becomes necessary to discharge the
item after the test.
3. DC testing unlike AC testing only charges the insulation in one polarity. This becomes
a concern when testing products that will actually be used at AC voltages. This is a key
reason that some safety agencies do not accept DC testing as an alternative to AC.
4. When performing AC hipot tests the product under test is actually tested with peak
voltages that the hipot meter does not display. This is not the case with DC testing since a
sinewave is not generated when testing with direct current. In order to compensate for
this most safety agencies require that the equivalent DC test be performed at higher
voltages than the AC test. The multiplying factor is somewhat inconsistent between
agencies which can cause confusion concerning exactly what equivalent DC test voltage is
appropriate.
The Ground Continuity Test
The Ground Continuity test is checking to verify that there is low impedance path between
the chassis and the safety ground wire of the line cord. A low impedance ground system is
critical in ensuring that in the event of a product failure a circuit breaker on the input line
will act quickly to protect the user from any serious electrical shock.
International compliance agencies such as CSA, IEC, TÜV, VDE, BABT and others, have
requirements calling out this test. A low current test merely indicates that there is a safety
ground connection. It does not completely test the integrity of the connection that would
be accomplished by using much higher currents in the range from 10 to 30amps. The high
current test is known as a Ground Bond test.
The Ground Continuity test verifies that the ground circuit between the Continuity and
Return panel jacks on the Hypot II is below 1ohm while test at a current of 100mA. This
function can be enabled or disabled through software, when a ground circuit is not
provided on the device under test or test requirement are not needed.
The Insulation Resistance Test....
Some dielectric analyzers come with a built in insulation resistance tester. Typically, the
IR function provides test voltages from 500 to 1,000 volts DC and resistance ranges from
kilohms to gigaohms. This function allows manufacturers to comply with special
compliance regulations. BABT, TÜV and VDE are agencies that may require an IR test
on the product before a Hipot test is performed. This typically is not a production line test
but a performance design test.
The insulation resistance test is very similar to the hipot test. Instead of the go/no go
indication that you get with a hipot test the IR test gives you an insulation value usually in
Megohms. Typically, the higher the insulation resistance value the better the condition of
the insulation. The connections to perform the IR test are the same as the hipot test. The
measured value represents the equivalent resistance of all the insulation which exists

INTRODUCTION
12
between the two points and any component resistance which might also be connected
between the two points.
Although the IR test can be a predictor of insulation condition it does not replace the need
to perform a Dielectric Withstand test.

KEY FEATURES & BENEFITS OF MODEL 4500D
1. No load setup of trip current and output voltage.
This provides the operator with an easy and safe way to set trip currents and output
voltages since parameters are set without the high voltage activated.
2. Automatic storage of test program.
The Model 4500D powers up with the parameters that were used during the last test
to avoid operator set-up errors.
3. All parameters for the setups can be adjusted through a simple menu driven
program.
The easy to follow setup screens ensure that the operator correctly sets up all test
parameters.
4. Tamper proof front panel controls.
This makes it possible to limit user access to the setup screens so that only authorized
personnel with a security code can change test parameters.
5. Line and load regulation.
This system maintains the output voltage to within 1% from no load to full load and
over the line voltage range to ensure that test results remain consistent and within
safety agency requirements.
6. The LCD display allows monitoring of current down to 100 microamps AC.
This allows the 4500D to be used even when test requirements only allow a very low
level of acceptable leakage current.
7. Electronic dwell settings.
The electronic dwell control helps keep test results consistent by ensuring that the test
duration is the same for each product tested.
8. PLC remote inputs and outputs.
The standard 9 pin interfaces provide outputs for Pass, Fail, and Test in Process.
Inputs include Test and Reset. This gives the user all the basic remotes required to
configure the 4500D through simple PLC relay control.
9. Front panel LCD displays test parameters and results.
A front panel LCD allows the operator to monitor the test. The display holds the
results after a test item failure so that the operator can easily review the test results.
Indications of high fail and continuity failure are clearly displayed.
10. Maximum output current of 100 milliamps AC.
This instrument offers enough output current to test capacitive loads in AC mode and
allows compliance with standards requiring 500VA output.

SPECIFICATIONS
16
11. Software calibration control.
The 4500D is calibrated through the front panel keypad. All calibration information is
stored in non-volatile memory. This allows the 4500D to be completely calibrated
without removing any covers and exposing the technician to hazardous voltages.
12. User selectable output voltage frequencies of 50 or 60 hertz.
The 4500D is designed for the global market. This feature makes it simple for the user
to select the output frequency in the AC hipot mode so that products can be tested at
the same frequency they will be used at.
13. Output voltage fine adjustment.
To make 4500D usable in all types of applications, the operator can manually bring the
voltage up or down in 10 volt increments by simply pressing the up and down arrow
keys. This makes it very easy to adjust the output voltage even while the 4500D is in
the dwell mode so you can analyze test results at different voltages.
14. Built-in Continuity test mode.
The 4500D meets ground continuity test requirements called out by UL and other
safety agencies.
15. Flashing high voltage indicator.
A flashing LED located directly over the high voltage terminal clearly indicates when
high voltage is active to provide maximum operator safety.
16. Comes complete with a test box for products terminated in a line cord.
The standard US style receptacle box allows easy testing of hipot and continuity on
line cord terminated products. As an additional benefit, termination boxes are
available for testing products with line cords configured for other countries.
17. User selectable input voltage.
The 4500D can be switched for either 115 or 230 volt input operation through an easy
access rear panel mounted switch to allow it to be used in any country.
18. Low-current sense.
Monitors the minimum level of current flow, thus ensuring that the DUT is properly
connected and that the hipot test is being performed.
19. Electronic ramping.
Provides a gradual and timed method to increase output voltage to the DUT,
minimizing any damage from quickly over-applying high voltage to sensitive DUTs.
20. Test setup memories.
The operator can store and recall test setups, thus eliminating the need to re-enter
setup information.
21. Built-In Remote Interlock
A remote interlock provides a way to connect a safety enclosure or other safety device
to protect the operator from exposure to high voltage.
