Calls attention to a procedure, practice, or condition that could
possibly cause damage to equipment or permanent loss of data.
1.3. Glossary of Terms
(As used in this manual)
Alternating Current, AC: Current that reverses direction on a regular basis. Utility power is
usually generated in the form of a sinusoid at a frequency of 60 times per second in the United States
and 50 times per second in other countries.
Arc: A partial momentary breakdown due to the force of a strong electric field on closely spaced
conductors, sometimes evidenced by corona or a luminous flashover.
Breakdown: The failure of insulation to effectively prevent the flow of current. If the test voltage is
gradually raised, breakdown will begin suddenly at a certain voltage level and current flow will not be
directly proportional to voltage. Once a breakdown occurs, especially for a period of time, the next
gradual application of voltage will often cause a breakdown to begin at a lower voltage.
Conductor: A solid or liquid material which permits the flow of electrons. A material which has a
volume resistivity of no more than 103 Ω-cm.
Current: The movement of electrons through a conductor. Current is measured in amperes (A),
milliamperes (mA), microamperes (uA). Symbol = I
Dielectric: An insulating material that is positioned between two conductive materials in such a way
that a charge or voltage may appear across the two conductive materials.

____________________________________________________________________________
3
Direct Current, DC: Current that flows in one direction only. The source of direct current is said to
be polarized and has one terminal that is always at a higher potential than the other.
Frequency: The number of cycles an AC waveform repeats over time. Usually given in Hertz (Hz).
Ground: Refers to the point of low potential in a circuit to which all other voltages are referenced.
May or may not be tied to the earth. Also referred to as Earth.
Hot: Used to refer to the test lead or output side of an instrument that is at high potential.
Impedance: The property of capacitive or inductive items to limit certain frequencies.
Insulation: Gas, liquid or solid material which has a volume resistivity of at least 1012 Ω-cm and is
used for the purpose of restricting current flow between conductors.
Leakage: AC or DC current flow through insulation and over its surfaces. Current flow is directly
proportional to voltage. The insulation is thought of as a constant impedance unless breakdown
occurs.
Neutral: The point of low potential in a circuit to which all other voltages are referenced. Also known
as Common.
Peak Current: The maximum amplitude of an AC current waveform. For a sinusoid, 1.414 x the
RMS value.
Power: The amount of work performed by an energy source over time, given in Watts (W).
PF (Power factor): Power Factor = W/VA where W =Watts (Real Power) and VA =Volts x Amps
(apparent power). It is important to note that the closer the power factor is to "1" the more resistive the
DUT is. The closer the power factor is to 0 the more reactive (inductive or capacitive) the DUT is.
Reactive Current: The current component due to the reactive impedance of a load. Also called
imaginary current.
Real Current: The current component due to the resistance of a load.
Resistance: The property of a substance that impedes current and results in the dissipation of
power in the form of heat. The practical unit of resistance is the ohm (Ω). Symbol = R
Return: The path by which current returns to a source.
RMS: The Root Mean Squared value of a voltage or current waveform. An RMS waveform delivers
the same amount of energy to a load as a DC waveform of the same value. For a sinusoid, the RMS
value is .707 x the peak value.
Total Current: The vector sum of the real current component and the reactive current component
produced by an applied voltage.

is not properly maintained and safety checked annually. See section 1.1. Warranty
Policies for more information.
1.4.2. Test Station
Location
Select an area away from the mainstream of activity where employees do not walk
while 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 test operators should be allowed inside.
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.”
Work Area
When possible, use the instrument on a non-conducting table or workbench. If you
cannot avoid using a conductive surface, be certain that it is connected to a good
earth ground and the high voltage connection is insulated from the grounded surface.
There should not be any metal in the work area between the operator and the location
where products being tested will be positioned. Any other metal in the work area
should be connected to a good ground, never left “floating”.
Keep the area clean and uncluttered. All test equipment and unnecessary test leads
should be removed from the test bench and put
away. It should be apparent to both the operator
and to any observers which product is under test,
which product is waiting to be tested and which
product has already been tested.
Power
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 case of
an emergency, anyone should be able to cut off the
power before entering the test area to offer
assistance.
More Information

Return Connection
When the instrument’s return is grounded, any internal and external stray leakage will
be monitored due to currents that flow from high voltage to earth ground (such as from
high voltage to the chassis of the instrument). These currents are inherent and will
cause errors when trying to monitor very low leakage currents in the micoamp range.
The output power supplies of this instrument are referenced directly to earth ground.
Any conductor that completes a path between the high voltage and earth ground will
form a completed circuit.
