increas es directly with frequency. This
effect is most noticeable in low total resis-
tance elements becaus e the inductive
reactance can be larger than the resistance,
even at frequencies as low as 20KHZ.
The p e rfo rm a nc e o f wire wo und
e le me nts is a ls o a ffe c te d b y inhe re nt
capacitance. Capacitance exists from turn
to turn and also between the winding and
the mandrel. Capacitance effects are most
s ignificant in high total res is tance ele-
ments.
Cermet elements are available in a
wide range of resistance values and tapers.
They offer essentially infinite resolution
and excellent stability in the most severe
e nvironme nta l c ond itions . S ta tic a nd
dynamic noise (CRV) performance is good
but not as good as that of conductive
plastic.
The temperature coefficient of cermet
elements, though not as good as wire-
wound elements, is better than conductive
plastic or carbon type elements. Linearity
is quite good for a film type element and
can be improved considerably for greater
dial setting accuracy by laser tailoring.
Frequency response of cermet materials
is very good and the practical application
range extends well beyond 100 MHZ.
CRV shall be tested using the circuit
a s s ho wn in Fig . 1 o n p a g e 253 o f
Potentiometer Handbook (or its equiva-
lent). The operating shaft shall be rotated
in both directions through 90% of the
adjustment travel for a total of 6 cycles.
Only the last 3 cycles shall count in deter-
mining whether or not a contact resis-
tance variation is observed at least twice
in the same area (within 5% ), exclusive of
the roll-on or roll-off points where the
wiper moves from the termination, on or
off, the resistance element. The rate of
rotation of the operating shaft shall be
such that the wiper completes 1 cycle in 5
seconds, minimum, to 2 minutes, maxi-
mum. The test current used shall be in
accordance with the table below, unless
otherwise specified.
Hybritron® Elements
This element is a combination of a
wirewound element with a conductive
plastic coating. It exhibits the temperature
c o e ffic ie nt a nd re s is ta nc e s ta b ility
approaching a pure wirewound element. It
displays the long operational life, essen-
tia lly infinite re s olution a nd low nois e
characteris tics of the pure conductive
plastic elements. The combination of the
two provides the major benefits of both
types of elements. Not recommended in
applications requiring high wiper currents.
Conductive Plastic Elements
Conductive plastic is a thick film ink,
similar to cermet, but has a smoother sur-
face. This characteris tic offers s everal
op e ra tiona l a d va nta ge s ove r c e rme t.
Dynamic noise characteristics (CRV or
output smoothness) and rotational life are
measurably improved as a result of the
surface smoothness. Resolution is essen-
tially infinite.

Absolute Minimum Resistance
Dielectric Withstanding Voltage
DEFINITION
DEFINITION
The resistance measured between the
wiper terminal and either end terminal
when the wiper is positioned to give a
minimum value on the measuring device.
The ability to withs tand under pre-
scribed conditions, a specified potential
of a given characteristic between the ter-
minals of each cup and expos ed con-
ducting surface of the potentiometer, or
between the terminals of each cup and
the terminals of every other cup in the
assembly without exceeding a specified
leakage current value.
Wirewound Elements
Wirewound elements offer good stabili-
ty, e xc e lle nt line a rity, low nois e , high
power capabilities and good operational
life.
Wire wo und e le m e nts o ffe r a wid e
selection of resistance values up to 500k
ohms.
One primary limitation of wirewound
elements is the finite res olution s teps ,
which result from the wiper moving from
turn to turn. (These steps are distinct, sud-
d e n, re p e a ta b le c ha ng e s in o utp ut.)
Resolution improves as resistance values
inc re a s e d ue to the m a nufa c turing
processes whereby smaller wire and a
higher number of turns are utilized.
In systems that might be sensitive to
such discrete steps, care should be taken
to select an element with resolution fine
enough to avoid difficulty.
TEST PROCEDURE
The wiper shall be positioned at one
end of the resistance element so that a
minimum va lue of re s is ta nc e s ha ll b e
measured as specified between the wiper
and the corresponding end terminal. The
same procedure shall be followed for the
opposite end of the resistance element.
TEST PROCEDURE
The magnitude of the test voltage shall
be specified. Connect the equipment by
applying the high voltage source between
the potentiometer terminals (interconnect-
ed) and the shaft or case. Raise the test
voltage from zero to the proper maximum
value at a rate of 500 volts per second
maximum. Maintain the test voltage at this
level while operating the shaft through
one full sweep of its mechanical travel in
a time interval of not less than 5 seconds
nor more than 60 seconds. Monitor the
Contact Resistance Variation (CRV)
DEFINITION

fied current and moved over the adjust-
ment travel in either direction at a con-
s tant s peed. The output variations are

TEST PROCEDURE
Independent Linearity

fied portion thereof.
out this test for evidence of damage, arc-
ing, breakdown, or leakage current in
excess of 1 milliampere. Upon completion
of the tes t, prior to dis connecting the
leads, gradually reduce the test voltage to
zero.
For ganged potentiometers, repeat the
fo re g o ing a p p lying the hig h vo lta g e
between the terminals of each cup and
the terminals of every other cup on the
potentiometer under test.
Mount the potentiometer in the con-
stant-speed drive (4 RPM) and excite it
with the power supply. Connect the wiper
and the power common lead to the input
of the filter and the output of the filter to
the oscilloscope. When a load is specified
for a conformity test, use that load for the
output smoothness test. When no load is
specified for the conformity test, apply a
load equal to 100 times the nominal resis-
tance value of the potentiometer under
test between the wiper and the CCW end
(unless otherwise specified).
The output smoothness is the largest
excurs ion voltage occurring ove r one
specified travel increment, divided by the
total applied voltage. Unless otherwise
specified, the travel increment is 1% of
the theoretical electrical travel.
TEST PROCEDURE
Consult factory.
Equivalent Noise Resistance (ENR)
Insulation Resistance
DEFINITION
DEFINITION
Any spurious variation in the electrical
output not present in the input, defined
quantitatively in terms of an equivalent
paras itic trans ient res is tance in ohms ,
appearing between the contact and the
re s is ta nc e e le me nt whe n the s ha ft is
rotated or translated. The equivalent noise
resistance is defined independently of the
resolution, the functional characteristics,
and the total travel. The magnitude of the
equivalent noise resistance is the maxi-
mum departure from a specified reference
line. The wiper of the potentiometer is
required to be excited by a specified cur-
rent and moved at a specified speed.
The re s is ta nc e to
a
s p e c ifie d
impressed DC voltage between the termi-
nals of each cup and the exposed con-
ducting surfaces of the potentiometer, or
between the terminals of each cup and
the terminals of every other cup in the
gang, under prescribed conditions.
Excursions occurring at the point of
abrupt changes in input slope (start, end,
and reversal) are not considered output
smoothness faults.
TEST PROCEDURE
Interconnect all electrically insulated
terminals of each cup of the potentiome-
ter. Connect the insulation resistance test
set to the terminal of the first cup and to
some exposed conducting surface (shaft,
housing, etc.) and apply the specified test
voltage. Unless otherwise specified the
test voltage shall be 500 VDC. Maintain
the test voltage at this level for 5 to 10
seconds before initiating movement of
the shaft through one full sweep of the
total mechanical travel in a time interval
of not less than 5 seconds nor more than
60 seconds. Monitor the indicated insula-
tion resistance during this voltage appli-
cation, the insulation resistance is the
m inim um va lue o b s e rve d d uring the
movement of the shaft.
Power Rating
DEFINITION
The maximum power, in watts, that a
potentiometer can dissipate across the
entire resistive element under specified
conditions while meeting specified oper-
ating performance requirements.
TEST PROCEDURE
The potentiometer shaft is cycled not
less than ten times over a minimum of
95% of the electrical continuity travel
within the rated travel speed of the poten-
tiometer just prior to making noise mea-
s urements . The potentiometer s haft is
then connected mechanically to the con-
s ta nt s p e e d d rive a nd e le c tric a lly
connected to the tes t circuit. With the
constant speed drive engaged, the poten-
tiometer noise characteristic may then be
noted on the oscilloscope as the wiper
traverses one complete cycle over the full
electrical continuity travel and the maxi-
mum values are compared to the speci-
fied limit.
Resolution
DEFINITION
A measure of the sensitivity to which
the output of a potentiometer may be set.
(Applicable to wirewound potentiometers
only.)
Theoretical resolution; the reciprocal of
the number of turns of wire in the resis-
tance winding in the actual electrical trav-
el, expressed as a percentage.
Travel resolution; the maximum value
o f s ha ft tra ve l (in d e g re e s fo r ro ta ry
devices) in one direction per incremental
voltage stop in any specified portion of
the resistance element.
Vo lta g e re s o lutio n; the m a xim um
incremental change in output ratio with
shaft travel in one direction in any speci-
fied portion of the resistance element.
For ganged potentiometers, repeat the
procedure for each cup applying the high
voltage between the terminal of each cup
and the exposed conducting surface of
the potentiometer.
If only ra nd om s p ike s of nois e a re
no te d , the p o te ntio m e te r s ho uld b e
cycled again. If the random spikes are
repetitive, the maximum values should be
noted. Otherwise do not consider the ini-
tial measurements as noise.
Output Smoothness
DEFINITION
The spurious variations in the electri-
cal output not present in the input. They
are measured for specified travel incre-
ments over the theoretical electrical travel
and expressed as a percentage of the
total applied voltage.
TEST PROCEDURE
Consult factory.

Definitions and Test Procedures
Temperature Coefficient of Resistance
DEFINITION
The unit c ha nge in re s is ta nc e p e r
degree Celsius change from a reference
temperature, expressed in parts per mil-
lion per degree Celsius using the following
formula:
TC = [(R1-R2)/R1(T2-T1)] x 106
WHERE: R1 = Resistance at reference
temperature in ohms
R2 = Resistance at test
temperature in ohms
T1 = Reference temperature
in degrees Celsius
T2 = Test temperature in
degrees Celsius
TEST PROCEDURE
Position the wiper of the potentiometer
to be tested off of the actual electrical
travel or at a point to minimize the total
resistance if no over travel exists. Subject
the potentiometer to the specified test
temperature(s ). The total res is tance is
measured after temperature chamber has
been stabilized for the test temperature
for a minimum of 30 minutes (avoid over
aging). The reference temperature of 25
degree Celsius shall be used for all elevat-
ed and reduced temperatures. Calculate
the (TC) by inserting the appropriate data
into the above formula and comparing the
result to the specification.
Total Resistance
DEFINITION
The DC resistance between the end
terminals of a potentiometer with the shaft
p os itione d s o a s to give a ma ximum
resistance value.
TEST PROCEDURE
With the VOM or DVM device (10ma
maximum current) connected between
the wiper and one end terminal, position
the wiper onto the electrical overtravel.
Reconnect the test leads of the measur-
ing device to the end terminals of the
potentiometer under tes t, the reading
obs erved is the total res is tance of the
potentiometer.
