INTRODUCTION
The RPM4 //m connector bloc is an accessory for
RPM4 parallel measurement mode operation. It
supplies single
TEST(+)
and
TEST(-)
ports to assure a
simple, leak free connection to both of the RPM4’s Q-
RPTs in parallel.
The //m connector bloc can only be used with RPM4s
that have two Q-RPTs of A7M or lower. Maximum
working pressure is 7 MPa (1 000 psi).
INSTALLATION INSTRUCTIONS
Install the four 1/8 in. M O-seal x 1/8 in. swage
adapters on the RPM4 TEST(+) and TEST(-) ports
(2). Remove the nuts and ferrules from each one of
the adapters.
Remove the two Philips head screws from the
extreme right and left hand corners of the RPM4 Hi
and Lo
Q-RPT modules (1, 3).
Remove the cover of the //m connector bloc by
removing the two top (5) and two lateral (4) button
head socket screws.
Connect the four 1/8 swage F connections of the
//m connector (6) to the four 1/8 swage M
adapters on the RPM4
TEST(+)
and
TEST(-)
ports.
Attach the //m connector bloc (7) to the RPM4
using the two M3 screws supplied with the kit.
Install the screws in the lower right hand corners
of the Q-RPT modules (1, 3).
