    DTR-7.4 ADJUSTMENT AND CONFIRMATION PROCEDURES 1 Idling current adjustment Before Idling current adjustment, turn the trimming resistors R6040 to R6046 to counter-clockwise. Connect the DC voltmeter at the sockets P6080 to P6086. After turn POWER to ON, adjust the trimming resistors R6040, R6041 and R6042 so that the reading of voltmeter becomes 11 mV.
  • Page 72 DTR-7.4 ADJUSTMENT AND CONFIRMATION PROCEDURES 2 3. Confirmation of Current detection circuit Set the unit to "TEST-1-00". Connect the differentiating circuit and apply the 200Hz square signal to MULTI CHANNEL INPUT terminal of each channel. Adjust the attenuator or Volume so that the output level becomes 35V p-p.
