Set scan intervals according to the application and with consideration for signal instability or
interference effects on the signal by external sources. Long scan times will result in slower
response time.
AVI. Analog Voltage input scaling examples by adjusting Gain, Bias & Slope parameters (04-02~04-05).
(1) Positive Bias type (04-04= 0) and effects of modifying Bias amount by parameter 04-03 and
Slope type with parameter 04-05 are shown in Fig 1&2.
