: The device can save a specific output value as a default, which it will automatically output upon being powered on. Programming and Configuration (Key Parameters) The user manual defines specific parameter codes ( F001cap F 001 F002cap F 002 , etc.) to customize the unit's behavior: Description F001 Adjustment Type Sets the knob to "Coarse" (0) or "Fine" (1) adjustment. F002 Output Range Configures ranges such as F003 Display Mode Switches display between actual signal value (0) or scale (1). Operational Instructions
