Bias Adjustment
1. Rotate fully the bias adjusting semi-fixed resistors (RV500,
RV600) to the MIN position (counterclockwise).
2. Connect a digital voltmeter to the CN500 and CN600.
3. Set the slidack to 0 V, and press the Ubutton (ON) on the
set.
4. Raise gradually the slidack voltage up to the rated voltage
(230 V).
5. At this time, confirm that the SP relay is turned on (it will
click), and at the same time, the LED on the Ubutton changes
from red to green.
6. Adjust the RV500 and RV600 so that a reading of digital volt-
meter is 10 mV ± 2 mV.
7. Return the slidack to 0 V, and press the Ubutton (OFF) on
the set.
