No data is saved to the device, and the EPROM may be damaged.
Yes. You can use sensors for pressures up to 4000 bar. This requires sending in the device to modify the device software. In addition, the hose that will be used for the connection also needs to be identified because our testing hose is not designed for pressures exceeding 10 bar.
The leakage quantity pump may have expired. The leakage quantity pump must have a valid inspection seal in order to ensure precise measurements. The leakage quantity pump is valid for one year.
Remove the scale from the ROKLIMA® casing and place it on a level surface. Now confirm by pressing the “minus” and “R” buttons simultaneously. “Tare” appears on the display. Confirm the taring by pressing the “C” function key. The scale has now been zeroed. The display shows “0.000”.
The coolant circuit is under pressure, i.e. the user is attempting to evacuate a pressurized system. The pressure sensor inside the ROKLIMA® detects this and prevents the vacuum pressure from starting. Follow these steps: Make sure that coolant circuit is not under pressure. This may require restoring the coolant circuit to its delivery state, i.e. draining all coolant back into the external unit. Please follow the operating instructions provided by the device manufacturer when performing this procedure. The pressure in the lines being evacuated can then be released, for example, using the service valve of the air conditioner and you can proceed with the steps for evacuating the system.
