5. Operating Instructions

Operating the CC220 scale is straightforward:

1. Power On: Press the POWER button on the remote display unit to turn on the scale. The LCD will illuminate and display '0.00' or '0.0'.
2. Select Units: Use the UNIT button to cycle through available measurement units (e.g., lbs, kg, oz). Select the desired unit for your measurement.
3. Tare Function: If you are using a container or hose that needs to be excluded from the measurement, place it on the scale platform first. Then, press the TARE button. The display will reset to '0.00', effectively zeroing out the weight of the container.
4. Weighing: Carefully place the item to be weighed (e.g., refrigerant cylinder) onto the center of the scale platform. The weight will be displayed on the LCD.
5. Charging: When charging, monitor the display for the precise amount of refrigerant added or removed.
6. Power Off: Press and hold the POWER button to turn off the scale. The scale also features an automatic OFF option to conserve battery life.
