Item
Measure total resistance between the resistance element and terminals (#1 and #3) with the contact arm positioned
against a stop. The positioning of the contact arm and terminal shall be the same for subsequent total resistance
measurements on the same device. Use the test voltage specified in Table-1 for total resistance measurements.
This voltage shall be used for all subsequent total resistance measurements.
Position the contact arm at the extreme counterclockwise limit of mechanical travel and measure the resistance
between the contact arm and the corresponding end terminal. Then, position the contact arm at the extreme clock-
wise limit of mechanical travel and measure the resistance between the contact arm and the corresponding end ter-
minal. During this test, take suitable precautions to ensure that the rated current of the resistance element is not
exceeded.
Contact resistance variation shall be measured with the measuring circuit shown in Figure-1, or its equivalent. The
adjustment rotor (screw) shall be rotated in both directions through 90% of the actual effective-electrical rotational
angle(number of turns) for a total of 6 cycles. Only the last 3 cycles shall count in determining whether or not a con-
tact resistance variation is observed at least twice in the same location, exclusive of the roll-on or roll-off points
where the contact arm moves from the termination, on or off, the resistance element. The rate of rotation of the
adjustment rotor (screw) shall be such that the adjustment rotor (screw) completes 1 cycle for 5 seconds minimum to
2 minutes maximum. The test current used shall follow the value given in Table-2 unless otherwise limited by power
rating.
The trimmer potentiometer shall be subjected to the following each temperature (see Table-3) for 30-45 minutes.
Temperature coefficient of resistance shall be applied to the following formula.
TCR=
Note) * : Reference temperature
The wiper shall be set at approximately 40% of the actual effective-electrical rotational angle (number of turns). An
adequate DC test potential shall be applied between the terminal #1 and the terminal #3. The voltage between the
terminal #1 and the terminal #3, and the voltage between the terminal #1 and the terminal #2, shall be measured
and applied to the following formula.
