5-2-5 Internal Camera Temperature Check (2)
For this adjustment, use the same conditions as those specified in 5-2-2 Iris Adjustment (Coarse Adjustment)
Procedure)
(1) Press the SLOW KEY, check the internal temperature sensor in the camera.
(Within about five minutes, perform this step as soon as power is turned on.)
(2) Record the current internal temperature.
Temperature about five minutes after power-on T2 = _________
(3) Calculate an increase in the internal camera temperature [°C], and check that it is less than 7 [°C].
Increase in internal camera temperature [°C] = T2 - T1
Example: Under the condition that T1 = -9 and T2 = -4, an increase in
temperature is calculated as follows: T2 - T1 = - 4 - (-9) = 5 [°C]
(4) If an increase in the internal camera temperature exceeds 7°C, turn power off and then wait until a temperature level of less than 7°C
is reached. Then, proceed to items 5-2-6 and subsequent.
Note)
Remember that power cannot be disconnected just by turning off the POWER switch. Be sure to release the
service mode, and then turn off the POWER switch or unplug from the CA receptacle.

•
Internal camera temperature difference T [°C] = (Current internal camera temperature) - (Internal camera tempera-
ture at CCD image adjustment (low temperature)
•
A value of internal camera temperature difference is represented in decimal notation. When the value is negative, it
is indicated in blinking form. (When the value is positive, it is indicated in steadily turned-on form.)
