6. آپريٽنگ هدايتون
6.1 پاور کوليو
After completing all wiring, apply power to the meter. The LED displays will illuminate, showing the current Process Value (PV) and potentially a Set Value (SV).
6.2 بٽڻ جا ڪم
- سيٽ بٽڻ: پيرا ميٽر سيٽنگ موڊ ۾ داخل ٿيڻ ۽ چونڊن جي تصديق ڪرڻ لاءِ استعمال ڪيو ويندو آهي.
- <<RST button: Used to shift digits during value setting or to reset certain functions.
- Up (↑) button: Used to increase values or navigate through menu options.
- Down (↓) button: Used to decrease values or navigate through menu options.
6.3 Basic Operation (General)
While specific programming steps are not detailed in the provided information, typical operation involves:
- Viewing PV/SV: The main display shows the current Process Value (PV). The smaller display shows the Set Value (SV), which might be an alarm setpoint or other configured parameter.
- سيٽنگ پيٽرولر: Press the SET button to enter the parameter setting mode. Use the Up/Down arrows to select parameters and adjust their values. Use the <<RST button to shift between digits when setting numerical values. Press SET again to confirm and save changes.
