SMpeDciOfipceantioTnyspeanadndTePsVt MM4eAth_oAd0s1 Series Specifications and Test Methods
The tests and measurements shall be conducted under the condition of 15 to 35°C of temperature, 25 to 75% of relative humidity and 86 to 106 kpa of
atmospheric pressure unless otherwise specified. In case when entertained a doubt in judgment obtained from results measured in accordance with the
above mentioned conditions, the tests and measurements shall be conducted under the condition of 25±2°C of temperature and, 45 to 55% of relative
humidity and 86 to 106 kpa of atmospheric pressure.

Test Methods
Measure total resistance between the resistance element and terminals (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 whenever a
subsequent total resistance measurement is made.

Table-1 Total resistance test voltage
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 below, or its equivalent. The
operating wiper shall be rotated in both directions through 90% of the actual effective-electrical travel for a total of 6
cycles.
The rate of rotation of the operating wiper shall be such that the wiper completes 1 countin determining whether or
not a contact resistance variation is observed at least twice in the same location. The test current shall follow the
value given in Table-2 unless otherwise limited by the power rating.

The wiper contact point shall be pre-setted at about 50% position of effective rotational angle. After that, the poten-
tiometer shall be placed in a chamber at 40±2°C and 90 - 95% without loading for 500±12 hours.
The resistance value shall be measured after keeping the potentiometer in a room for 5±1/6 hours.
The wiper contact point shall be pre-setted at about 50% position of effective rotational angle. After that, the poten-
tiometer shall be placed in a chamber at 70±2°C without loading for 500±12 hours. The resistance value shall be
measured after keeping the potentiometer in a room for 1.5±1/6 hours.
The wiper contact point shall be pre-setted at about 50% position of effective rotational angle. After that, the poten-
tiometer shall be placed in a chamber at 40±2°C and 90 - 95% with loading the 1/2 rated voltage between #1 and #2
terminals, intermittently 1.5 hours ON and 0.5 hours OFF for 1000±12hours.
The resistance value shall be measured after keeping the potentiometer in a room for 5±1/6 hours.
The wiper contact point shall be pre-setted at about 50% position of effective rotational angle. After that, the poten-
tiometer shall be placed in a chamber at 70±2°C (50±2°C for PVZ) with loading the 1/2 rated voltage between #1
and #2 terminals, intermittently 1.5 hours ON and 0.5 hours OFF for 1000±12 hours. The resistance value shall be
measured after keeping the potentiometer in a room for 1.5±1/6 hours.
The wiper contact point shall be pre-setted at about 50% position of effective rotational angle. After that, the poten-
tiometer shall be subjected to Table-3,Table-4 temperature for 5 cycles. The resistance value shall be measured
after keeping the potentiometer in a room for 1.5±10 minutes.
