*1 The zero adjustment value and gain adjustment value are recorded in the flash ROM inside the QD73A1 by turning on
Zero/gain adjustment data writing request signal (Y1A), and they are not erased even at a power-off.
*2 If an error occurs in the zero/gain adjustment mode, the ERR. LED turns on. If the ERR. LED is on, turn on Error reset
signal (Y28) then perform zero/gain adjustment again.
