Checking/Adjustments
1. Connect the digital voltmeter between the check
terminals of the extension board EX-632 and power
supply unit, and check that the voltage of each check
terminals satisfies the specifications.
2. If not satisfied, adjust using the respective controls.
3. Check that the voltage of check terminal satisfies the
specification.
If the specification of +3.3 V _2 voltage is not
satisfied, adjust using the RV1/DD-33 (C-3).
(See Sec. 6-2-2. DD-33 Board Voltage Adjustment.)

4. Turn OFF the breaker, insert the extension board EX-
632 into DCP2 slot (twoth from the left) along the
guide rail.
5. Turn ON the breaker.
6. Check that the voltage of check terminal satisfies the
specification.
If the specification of +3.3 V _2 voltage is not
satisfied, adjust using the RV2/DD-33 (C-1).
(See Sec. 6-2-2. DD-33 Board Voltage Adjustment.)
