5-5-1 Internal Camera Temperature Check (3)

(1) Adjustment Conditions
Movie/Still : Movie
Shotting mode : Program AE
AF : Closest focus
ZOOM : Telephoto-end
Electronic zoom : OFF
Image stabilizer : OFF
Preparation)
(1) For adjustment, provide the same tool and connections as in 5-2 "CCD Section (1)". (The LED light source should be removed
until item 5-5-2.)
Procedure)
(1) Press the SLOW KEY, check the internal temperature sensor in the camera.
(Perform this step about 20 to 50 minutes after power-on.)
(2) Using the internal camera temperature data, calculate a value of the current internal temperature, and record the calculated value.
Temperature 20 to 50 minutes after power-on T3 = ____________
(3) Calculate an increase in the internal camera temperature [°C], and check that it is in the range of 15[°C] to 20[°C].
Increase in internal camera temperature [°C] = (T2 - T1) + T3
(4) If an increase in the internal camera temperature exceeds 20°C, turn power off and then wait until a temperature level of less than
20°C is reached. Then, proceed to items 5-5-2 and subsequent.
If an increase in the internal camera temperature is less than 15°C, wait until a temperature level exceeding 15°C is reached.
Then, proceed to items 5-5-2 and subsequent.

Note)
The internal camera temperature check procedures are complete at this step. After checking the internal camera temperature
difference, be sure to reset DATA to 00.
