5. Test Method
SPECIFICATION No. JVR03Z-7148B
REFERENCE ONLY
The tests and measurements should 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.
If questionable results occur that have been measured in accordance with the above mentioned
conditions, the tests and measurements should 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.
When the trimmer potentiometer is tested after soldering on PCB, it should be tested after being kept
in a room (15 to 35°C, 25 to 75%RH) over 24 hours except ” 5.12 Resistance to soldering heat“.
5.1 Contact resistance variation (CRV)
Contact resistance variation should be measured with the measuring circuit shown below, or its equivalent.
The operating wiper should 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 should be such that the wiper completes
1 count in determining whether or not a contact resistance variation is observed at least twice in the same
location.

5.3 Permitted force of Driver plate
A static load of 4.9N
(Ref; 500gf)
should be applied on the driver plate of the trimmer potentiometer for 5+1/-0
second. The load should be applied on driver plate uniformly by the 3mm-size plate of push-pull gage.
5.4 Soldering strength
The trimmer potentiometer should be soldered under the soldering condition described in paragraph 7.2(1) on
standard land pattern described in 9. Outline dimensions. A static load of 9.8N
(Ref; 1kgf)
should be applied
from rear side through the hole opened in the center of PCB by the 1.0±0.1mm dia. stick for 5 second.

5.5 High temperature exposure
SPECIFICATION No. JVR03Z-7148B
The wiper contact point should be preset at about 50% position of effective rotational angle. After that, the
trimmer potentiometer should be kept in a chamber at 70±2°C without loading for 500±12 hours. The
resistance value should be measured after keeping the trimmer potentiometer in a room for 1.5±1/6 hours.
5.6 Humidity exposure
The wiper contact point should be preset at about 50% position of effective rotational angle. After that,
the trimmer potentiometer should be kept in a chamber at 40±2°C and 90 to 95% without loading for 500±12
hours. The resistance value should be measured after keeping the trimmer potentiometer in a room for 5±1/6
hours.
5.7 Load life
The wiper contact point should be preset at about 50% position of effective rotational angle. After that, the
trimmer potentiometer should be kept in a chamber at 50±2°C 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
should be measured after keeping the trimmer potentiometer in a room for 1.5±1/6 hours.
5.8 Humidity load life
The wiper contact point should be preset at about 50% position of effective rotational angle. After that, the
trimmer potentiometer should be kept in a chamber at 40±2°C and 90 to 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 should be measured after keeping the trimmer potentiometer in a room for 5±1/6 hours.
5.9 Temperature cycle
The wiper contact point should be preset at about
50% position of effective rotational angle. After that,
the trimmer potentiometer should be subjected to
Table 2 temperatures for 5 cycles. The resistance
value should be measured after keeping the trimmer
potentiometer in a room for 1.5±1/6 hours.
