7. Иштөө нускамалары
7.1 Кубат күйгүзүлдү
After all connections are made and verified, turn on the main power supply. The 4-digit LED display will illuminate and show the current measurement value (PV).
7.2 Өлчөөлөрдү окуу
The primary display shows the Process Value (PV), which is the measured input signal converted to the configured engineering units. The 'OUT' indicator may light up if an output function is active (though this model specifies 'Output: None', it's a common indicator on similar devices).

7.3 Параметр Орнотуулары
The 'SET' button is used to access and navigate through the meter's configuration menus. The Up (▲) and Down (▼) arrow buttons are used to adjust values, and the '<</RST' button is used to shift the cursor or reset. Specific parameter settings (e.g., input type selection, scaling, decimal point position) are typically detailed in the full manufacturer's manual. For basic operation, the meter should display readings automatically once the correct input type is configured.
