Using Gain and Bias to Adjust Output Signal Level
When viewing a gain setting parameter (H4-02 or H4-05) on the digital operator, the analog output will supply a voltage signal
equal to 100% of the monitor value (including changes made from bias and gain settings). When viewing a bias setting
parameter (H4-03 or H4-06), the analog output voltage will supply a signal equal to 0% monitor value.
Example 1: Set H4-02 to 50% for an output signal of 5 V at terminal FM when the monitored value is at 100%.
Example 2: Set H4-02 to 150% for an output signal of 10 V at terminal FM when the monitored value is at 76.7%.

n H4-07, H4-08: Multi-Function Analog Output Terminal FM, AM Signal Level Selection
Sets the voltage output level of U parameter (monitor parameter) data to terminal FM and terminal AM using parameters
H4-07 and H4-08.
Set jumper S5 on the terminal board accordingly when changing these parameters.
