Adjustment And Confirmation - Pentax 77420 Service Manual

IV. Adjustment and Confirmation
*Following contents are adjustment and confirmation after complete [III. Assemble procedure of main body]
*[Preparation for adjustment] should be completed.
*[Caution] When execute adjustment with program software, each setting will be initialized.
1. [Confirmation] Confirmation for Battery consumption current
[Required equipment] □DC coupler □DC cable □Power supply (DC8.3V/3A or above)
[Caution] There are two kind of method for confirming Battery consumption current.
Depending on type of battery, select either method as followings.
*Select DC coupler with affix insulation tape or DC coupler without affix insulation tape.
① Use DC coupler without affix insulation tape: condition  Using external power supply (AC
② Use DC coupler with affix insulation tape: conditionUsing AA batteries
Method for checking
[Caution] Be sure to set the correct voltage. Do not mistake to set type of power source.
① Connect DC cable to the power supply and set DC6.0 or 8.3V (3A).
② Install DC coupler into battery chamber.
③ Connect DC cable to DC coupler. Confirm that there must be neither short nor leakage.
[Caution]If there is short circuit, disconnect the power immediately.
④ Turn on the power and release 3 times.
⑤ [Confirmation] Turn off the power and confirm the battery consumption current. (Refer to below table)
⑥ Confirm other current if necessary. (Refer to technical information)
