Low Temperature Operation
(Only for PVF2 and
PVM4A---D01)
13
The trimmer potentiometer should be placed in a chamber at a temperature of -25±3°C (-55±3°C for PVM4A---
D01 series) 48±4 hours without loading. The trimmer potentiometer should be removed from the chamber, and main-
tained at a temperature of 25±5°C for 1-2 hours

Rotational Life14
1)PV-- series
Full rated continuous working voltage not exceeding the maximum rated voltage should be applied with the circuit
shown in the figure. The adjustment rotor (screw) should be continuously cycled through not less than 90% of effec-
tive-electrical rotational angle (number of turns), at the rate of 1 cycle for 5 seconds minimum to 2.5 minutes maxi-
mum for total of 200 cycles.
2) PVG3, PVG5 series
The adjustment rotor (screw) should be continuously cycled though not less than 90% of effective-electrical rotation-
al angle (number of turns), at the rate of 1 cycle for 5 seconds minimum to 2.5 minutes maximum for a total of 50
(100 for PVG5) cycles, without loading.
3) PVF2, PVM4A---D01 series
The wiper should be rotated over 90% of the effective rotational angle without loading at a speed of 10 cycles per
minute, for 100 cycles continuously.
