MEH-P5100R,P5150 6. ADJUSTMENT 6.1 ADJUSTING THE MD SECTION 1) Precautions Since the single voltage (3.3V) system is being employed for the regulator of this equipment, the reference potential for the servo signals becomes Vc (1.65V, approximately). In this manual, the Vc reference potential will be indicated as **Vc (e.g. 1.5Vc) and the reference GND will be indicat- ed as **V. - Page 66 MEH-P5100R,P5150 - Grating adjustment 1) Regarding the TEST Disc When performing grating adjustment and grating confirmations, use the high reflection Disc (MMD-110). When confirming the operation state and automatic adjustment state, us the high reflection Disc (MMD-110) and low reflection Disc (MMD-212), respectively.
