4. راه اندازی

1. نصب باتری: Open the battery compartment (typically on the back of the unit) and insert the required batteries, observing correct polarity.
2. اتصال پروب: Connect the humidity/temperature probe to the designated port on the main unit. Ensure a secure connection.
3. روشن شدن اولیه: را فشار دهید ON button to power on the device. The display should illuminate and show initial readings.
4. Unit Selection (if applicable): If your model allows, select your preferred temperature unit (Celsius or Fahrenheit) using the ° C / ° F دکمه
5. قرار دادن: Position the thermohygrometer in the environment where measurements are required. Ensure the probe is exposed to the air and not obstructed.

5. دستورالعمل های عملیاتی

5.1 عملیات اساسی

• روشن/خاموش برق: را فشار دهید ON button to turn the unit on. Press the خاموش دکمه خاموش کردن
• نمایش خواندن: The display will show current relative humidity (RH%) and temperature (°C/°F).
• واحد دما: Toggle between Celsius (°C) and Fahrenheit (°F) by pressing the ° C / ° F دکمه
• نگهداری داده ها: را فشار دهید نگه دارید برای ثابت کردن مقادیر فعلی روی صفحه نمایش، دکمه را فشار دهید. برای رها کردن، دوباره فشار دهید.
• Minimum/Maximum Readings: را فشار دهید حداقل / حداکثر را فشار دهید تا view the minimum and maximum temperature and humidity readings recorded since the last reset. Press repeatedly to cycle through MIN, MAX, and current readings.
• Reset MIN/MAX: در حالی که viewing MIN/MAX readings, press the تنظیم مجدد button to clear the stored minimum and maximum values.

5.2 RS-232 Output

The device is equipped with an RS-232 port for connecting to a computer or data logger. This allows for real-time data acquisition and analysis. Refer to the specific software or interface instructions for your data collection system for details on establishing communication and data transfer protocols.
