Operation
In automatic modes, flow passes through the scale's solenoid valve; in manual modes, it is controlled by the cylinder valve, bypassing the solenoid valve.
Weighing
- 01With the platform empty, zero the reading using ZERO.
- 02Place the cylinder or object to be weighed centrally on the platform. Read the mass when the STABLE indicator appears.
Cylinder mass alarms
If you set the empty cylinder mass (TARE WEIGHT) before charging, the scale will sound an alarm when the cylinder mass falls below this value. The mass of refrigerant added will be displayed and the icon will flash. Press ENTER to end charging and return to weighing.
If you set the full cylinder mass (FULL WEIGHT) before recovery, the solenoid valve will shut off the flow and an alarm will sound when 80% of the setpoint is reached. The mass remaining to be recovered will be displayed and the icon will flash. Press ENTER to end recovery and return to weighing.
Automatic charging
- 01Connect the hoses as shown in figure 5 and check that the connections are correct and leak-tight.
- 02Place the refrigerant cylinder on the platform and wait for the reading to stabilise.
- 03Press CHARGE and enter the mass of refrigerant to be charged - minimum 50 g. Confirm with ENTER. The solenoid valve will open and refrigerant will begin to flow.
- 04Once the set amount of refrigerant has been transferred, the solenoid valve will automatically shut off the flow.
Charging with an inverted cylinder
- 01Fit the cylinder valve into the platform's M10 thread and connect the inverted cylinder and hose to it using the threads shown in figure 1.
- 02Connect the remaining hoses as shown in figure 6 and check that the connections are correct and leak-tight. Wait for the reading to stabilise.
- 03Press CHARGE and enter the mass of refrigerant to be charged - minimum 50 g. Confirm with ENTER. The solenoid valve will open and refrigerant will begin to flow.
- 04Once the set amount of refrigerant has been transferred, the solenoid valve will automatically shut off the flow.
Manual charging
- 01Connect the hoses as shown in figure 7 and check that the connections are correct and leak-tight.
- 02Place the refrigerant cylinder on the platform and wait for the reading to stabilise.
- 03Press CHARGE and enter the mass of refrigerant to be charged. Confirm with ENTER. Slowly open the cylinder valve by hand to start the flow.
- 04Monitor the change in mass throughout charging. Once the set amount of refrigerant has been transferred, the scale will sound a signal; immediately close the cylinder valve by hand.
Automatic recovery
- 01Connect the hoses as shown in figure 8 and check that the connections are correct and leak-tight.
- 02Place the recovery cylinder on the platform and wait for the reading to stabilise.
- 03Press RECOVERY and enter the mass of refrigerant to be recovered - minimum 50 g. Confirm with ENTER. The solenoid valve will open and refrigerant will begin to flow.
- 04Once the set amount of refrigerant has been transferred, the solenoid valve will automatically shut off the flow.
Manual recovery
- 01Connect the hoses as shown in figure 9 and check that the connections are correct and leak-tight.
- 02Place the recovery cylinder on the platform and wait for the reading to stabilise.
- 03Press RECOVERY and enter the mass of refrigerant to be recovered. Confirm with ENTER. Open the cylinder valve by hand to start the flow.
- 04Monitor the change in mass throughout recovery. Once the set amount of refrigerant has been transferred, the scale will sound a signal; immediately close the cylinder valve by hand.
After charging or recovery is complete, the display shows the gross cylinder mass. Example: with an initial gross cylinder mass of 10 kg, charging the system with 1 kg gives a final reading of 9 kg; recovering 1 kg into the cylinder gives 11 kg. To enter a 1 kg setpoint, press in sequence: CHARGE or RECOVERY, 1, ENTER.
Small variations in the mass reading may occur during charging or recovery. They do not indicate a scale fault.
Finishing work
After completing the work, close the system valves and switch off the platform and remote control. Clean the scale and put it in the carry bag.
Calibration
The scale is factory calibrated. If the readings are incorrect, you can perform field calibration. Place the empty platform on a stable, level and hard surface, free from vibrations.
Certified calibration weights are recommended. The calibration weight range is 1–60 kg for MRS60 and 1–120 kg for MRS120. If you do not have a calibration weight, you can use an object of known mass, but this may reduce weighing accuracy. The greater the difference between the mass of the object being weighed and the mass of the object used for calibration, the greater the deviation.
- 01Switch on the platform and remote control, then wait for them to connect. Press and hold button 2 on the remote control to open the password screen.
- 02Enter code 123456 and confirm with ENTER to enter the pairing and calibration menu. Select option 3 - calibration.
- 03Place the calibration weight or object of known mass on the platform, select option 2 and enter its mass in kg, e.g. 5.0 kg. Confirm with ENTER.
- 04Remove the load from the platform. Select option 1 to calibrate the zero point, then press ENTER to exit to weighing.
