The DH500 test connection can be converted to 1/8 in. NPT M or 1/4 in. NPT M
using the 2.75 in. (7 mm) tube and DH500 F x 1/8 in. NPT M or DH500 F x 1/4 in.
NPT M adaptor supplied in the OPG1 accessories. Install the tube into the adaptor.
Any device connected to the OPG1 and/or HGC-30000-AF system should be purged
of air to the extent possible prior to being connected to the system (see
Section 3.2.5).
OPG1 covers a very wide range of pressures all the way up to 200 MPa (30 000 psi).
It is the user’s responsibility to assure that fittings and devices connected to OPG1
are rated for the pressures at which they will be used.
If the DUT connection is lower than the OPG1 oil tank, when the OUTLET valve is open
and the DUT connection is open, oil will run out of the tank through the
DUT connection.
