*1: Conversion impedance can be changed with the switch on the circuit board.
*2: The variable resistor VR on the circuit board must be used for making offset adjustments.
*3: Adjustable in 8 steps by using the BCD rotary switch on the circuit board.
*4: CLK, START, Trig and EOS pulse output format.
