13

Low Temperature Operation

(Only for PVM4A

---D01)

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 maintained at a temperature of 25±5°C for 1-2 hours.

12

Low Temperature Exposure

(Except for PVM4A

---D01)

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.

11

High Temperature Exposure

The trimmer potentiometer should be placed in a chamber at a temperature of 125±3°C 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.

10

Temperature Load Life

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 PV37 series). The trimmer potentiometer should be

removed from the chamber, and maintained at a temperature of 25±5°C for 1 to 2 hours.

9

Shock

1) PV

-- series

The trimmer potentiometer should be shocked at the 100G 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.

8

Vibration

1) PV

-- series

The trimmer potentiometer should be vibrated throughout the frequency range at the 20G level. A complete

frequency range, 10Hz to 2000Hz and back, should be made within 15 minutes for a total of 4 sweeps in each of the

three axis directions for a total of 12 sweeps.

7

Humidity

1) PV12, PV32, 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) PVG3, PVG5, PV36, PV37 series

The trimmer potentiometer should be subjected to the programmed humidity environment for 10 cycle (see Figure 3).

The trimmer potentiometer should be removed from the chamber, and maintained at a temperature of 25±5°C for

1.5±1/2 hours.

Figure 3

6

Temperature Cycle

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.
