Note 1. Use a separate stabilized power supply for the Amplifier Unit,
particularly when high resolution is required.
2. Wire the Unit correctly. Incorrect wiring may result in damage to
the Unit. (Do not allow wiring, particularly the linear output, to
come into contact with other lines.)
3. Use the 0-V line (blue) for the power supply and use the shield
wire (linear output ground) together with the linear output (black
line) for linear output. Each of these grounds must be used for
the designed purpose. When not using the linear output, con-
nect the linear ground (shield) to the 0-V ground.
