5. התקנה

5.1 התקנת סוללה

  1. Locate the battery cover on the back of the unit (refer to Figure 2, item 7).
  2. פתח את מכסה הסוללה.
  3. הכנס סוללה אחת של 9V, תוך הקפדה על קוטביות נכונה.
  4. סגור היטב את מכסה הסוללה.

Note: If the battery compartment seems tight, ensure you are using a standard-sized 9V battery and inserting it correctly. Do not force the battery.

5.2 Initial Power-On and Self-Test

Press the power button to turn on the device. The gauge will perform a brief self-test, and the display will illuminate. Ensure the battery icon indicates sufficient power.

5.3 חיבור צינורות

Connect appropriate refrigerant hoses (not included) to the inlet and outlet connections (refer to Figure 2, items 3 and 6) of the manifold gauge. Ensure all connections are tight to prevent leaks.

6. תפעול

6.1 Selecting Refrigerant Type

The L202 has a built-in database of 90 refrigerants. Use the function keys to scroll through and select the appropriate refrigerant for your system (e.g., R134A, R410A, R1234YF). The gauge will display the corresponding saturation temperature data.

Table listing 90 types of refrigerants supported by the MR CARTOOL L202 Digital Manifold Gauge, including R11, R12, R134A, R410A, R1234YF.

Figure 5: Three Common Working Modes

  • Refrigerant Measurement Mode: Displays real-time pressure and corresponding saturation temperature. This mode is essential for subcooling/superheating calculations and general system pressure monitoring.
  • Vacuum Percentagמצב e: Used when pulling a vacuum on a system. It shows the vacuum level as a percentage, indicating the efficiency of the vacuum process.
  • Leak Detection Mode: Assists in identifying potential leaks within the HVAC system by monitoring pressure changes over time.

6.3 המרת יחידה

The gauge supports multiple pressure and temperature units. Use the function keys to switch between:

  • יחידות לחץ: KPa, Bar, PSI, InHg, KgF/cm²
  • יחידות טמפרטורה: צלזיוס (°C), פרנהייט (°F)
