IMPORTANT NOTES
l. Before auditing your CD3 calibrator, determine
whether or not your calibrator has a relief valve
to adjust the injector supply pump pressure. CD3
calibrators manufactured after November 1984
incorporate this valve. See photograph at right.
The relief valve fits on the end of a length of
plastic tubing leading from a brass cross fitting at
the injector supply pump. The relief valve is
normally inserted into the calibration fluid
reservoir through 8 hole in the top of the reser-
voir.
If necessary, install the relief valve be£ore
starting the audit. A Relief Valve Kit, consisting
of all the necessary parts and installation instruc-
tions, is available for customer installation. The
kit can be ordered from Bacharach using part
number 77-0452.
2. The list of tools and equipment required to
perform an audit is in Section 1.1. Make certain
you have them before starting the audit.
