Clamp meter
a: The pressure gauges and rubber hoses must be dedicated for R410A. The
measuring range of the pressure gauges must be at least 4.0 MPa, and the
rubber hoses must withstand a pressure of at least 4.5 MPa. Ensure that the
rubber hoses match the 1/4 inch needle valves inside the unit. If necessary,
prepare needle valve adapters. When charging refrigerant, you are advised to
use a safety valve to prevent refrigerant leakage during the removal of a rubber
hose, which may cause frostbite.
b. The airflow of the vacuum pump should be within 2–4 L/s and the absolute
vacuum degree should be less than or equal to 60 Pa.
c: Dry nitrogen
d: A reducing valve should be used on the nitrogen cylinder port. The measuring
range of the reducing valve should be at least 4.0 MPa.
