Temperature Cycle6
The trimmer potentiometer should be subjected to Table 4 temperature for 5 cycles. The trimmer potentiometer
should be removed from the chamber, and maintained at a temperature of 25±5°C for 1~2 hours.
Specifications and Test Methods
Humidity7
1) PVC6, PV12, PV32, PV34 PVM4A---D01 series
The trimmer potentiometer should be placed in a chamber at a temperature of 40±2°C and a humidity of 90~95%
without loading for 250±8 hours (500±12 hours for PVM4A---D01 series). The trimmer potentiometer should be
removed from the chamber, and maintained at a temperature of 25±5°C for 5±1/6 hours.
2) PVF2 series
The trimmer potentiometer should be placed in a chamber at 60±2°C and 90~95% without loading for 1000±12
hours. The trimmer potentiometer should be removed from the chamber, and maintained at a temperature of 25±5°C
for 5±1/6 hours
2) PVG3, PVG5, PV01, PV22, PV23, PV36, PV37 series
The trimmer potentiometer should be subjected Figure-3 the programmed humidity environment for 10 cycle. The trim-
mer potentiometer should be removed from the chamber, and maintained at a temperature of 25±5°C for 1.5±1/2
hours.

Vibration8
1) PV-- series
The trimmer potentiometer should be vibrated throughout the frequency range at the 20G level. A complete frequen-
cy range, 10Hz to 2000Hz and back, should be made within 15 minutes for a total of 4 sweeps in each of the three
axis direction for a total of 12 sweeps.
2) PVF2 series
The trimmer potentiometer should be subjected to vibration at 0.3 inch amplitude. The frequency should be varied
uniformly between the approximate limits of 10Hz and 55Hz. This motion should be applied for period of 2 hours in
each of 3 mutually perpendicular directions (total of 6 hours).

Shock9
1) PV-- series
The trimmer potentiometer should be shocked at the 100G (50G for PV22 and PV23 series) level and should be
subjected to 4 shocks in each of the three axis directions for a total of 12 shocks.
2) PVM4A---D01 series
The trimmer potentiometer should be shocked at the 100G level and should be subjected to 3 shocks in each of the
six axis directions for a total of 18 shocks.
Temperature Road Life10
Full rated continuous working voltage not exceeding the maximum rated voltage should be applied intermittently
between terminal #1 and terminal #3 of the trimmer potentiometer, 1.5 hours on and 0.5 hours off, for a total of
1000±12 hours, at a temperature of 70±2°C (85±2°C for PV01 and PV37 series, 50±2°C for PVF2 series). The trim-
mer potentiometer should be removed from the chamber, and maintained at a temperature of 25±5°C for 1 to 2 hours.
High Temperature Exposure
(Except for PVF2)
11
The trimmer potentiometer should be placed in a chamber at a temperature of 125±3°C (150±3°C for PV22 series)
250±8 hours without loading. The trimmer potentiometer should be removed from the chamber, and maintained at a
temperature of 25±5°C for 1 to 2 hours.
Low Temperature Exposure
(Except for PVF2 and
PVM4A---D01)
12
The trimmer potentiometer should be placed in a chamber at a temperature of -55±3°C for 1 hours without loading.
Full rated continuous working voltage not exceeding the maximum rated voltage should be applied for 45 minutes.
The trimmer potentiometer should be removed from the chamber, and maintained at a temperature of 25±5°C for
approximately 24 hours.
