මෙහෙයුම් උපදෙස්
The Mastercool 52246 calculator simplifies subcool and superheat measurements into three main steps:
- Select Refrigerant:
- බලය ක්රියාත්මක කිරීමෙන් පසු, භාවිතා කරන්න UP සහ පහළට arrow buttons to scroll through the list of 37 pre-programmed refrigerants (e.g., R22, R32, R134a, R410A).
- ඔබන්න ඇතුල් කරන්න button to confirm your selection. The device will remember the last refrigerant used for convenience.
- Enter Pressure:
- Read the pressure from your manifold gauges.
- භාවිතා කරන්න UP සහ පහළට arrow buttons on the calculator to adjust the displayed pressure to match your gauge reading. The calculator supports pressure displays in Kg/cm², MPa, Bar, and PSI (0-600 PSI).
- Clamp තාපජ යුගල:
- ආරක්ෂිතව clamp the K-Type thermocouple onto the appropriate refrigerant line (e.g., suction line for superheat, liquid line for subcool).
- The actual temperature will be displayed in the upper right corner of the LCD.
The calculator will instantly display the calculated subcool or superheat temperature based on your inputs.
අතිරේක කාර්යයන්:
- Toggle Subcool/Superheat: ඔබන්න SH/SC button to switch between displaying subcool and superheat values.
- රඳවා ගැනීමේ කාර්යය: ඔබන්න අල්ලා ගන්න button to freeze the current readings on the display. This allows you to record the values even if the thermocouple is disconnected or the unit is turned off. The held data will remain until the instrument is powered off.
- ඒකක තේරීම: ඔබන්න ඒකක button to cycle through temperature units (°F or °C) and pressure units (Kg/cm², MPa, Bar, PSI).
