A COMPASS for molbox software installation CD is secured inside the COMPASS
for molbox User’s Manual Version 4.00. The CD may have
DHI
product literature
and other support software stored on it in addition to the COMPASS for molbox
installation program. The COMPASS manual is typically placed with other system
manuals inside the box with molbox1.
AFMETCAL systems include COMPASS for molbox software version 4.0 (AF CPIN 88M-MOLBOX1AF-T001-
00A)

For the “calibration exchange system” configuration, CalTool for molbox is included
in place of COMPASS. It is on 3.5 in. floppy disks or a CD secured inside the back
cover of its manual.

molblocs are shipped and stored in hard cases with sliding covers. The cases are
shipped inside cardboard boxes holding two molblocs each. There is a recessed
square on the front of the hard cases on which to apply the molbloc’s calibration
sticker if you desire. Calibration stickers are delivered with each calibration
certificate.
molbloc end fittings, pneumatic pressure quick connectors and communication ports
are capped for protection and cleanliness. Each molbloc has a black label on one side
listing the molbloc’s part number, serial number and ordering description. There is a
silver label on the other side listing the molbloc’s usable pressure and flow ranges and
indicating correct flow direction.
Four Viton O-rings and general molbloc mounting instructions are sealed in a bag
with each molbloc case. The Viton O-rings should be used in the VCR fittings when
mounting molblocs in molstics (see molstic Installation Instructions).
AFMETCAL configuration molblocs’ usable flow ranges differ from their nominal ranges due to the high
pressure calibrations performed on them. Both the operating pressure and flow range listed on each
molbloc’s silver label must be observed to ensure accurate flow measurements. See Section 3.1 for
explanation of molbloc operating pressure and usable flow range.
