Connecting Two Or More Amplifier Units; Introduction - Omron ZX2-LDA41 User Manual

Connecting Two or More Amplifier Units

Use a Calculating Unit to connect Amplifier Units when performing calculations between
CONTENTS
Amplifier Units and to prevent mutual interference between Sensor Heads.
The number of Amplifier Units that can be connected differs depending on the functions to
be used.
