hazard.
WARNINGS: The system operates on 24VDC from a power supply
(supplied by Uson or customer), which must be connected to an
earthed (grounded) power supply of 100-240VAC 50/60Hz.
The covers on the equipment should be removed only by personnel
trained to avoid the risk of electric shock. The power supply to the
equipment must be switched off and disconnected before removing
any covers.
Do not substitute the fuse rating. Always use the correctly rated fuse,
failure to do so may be hazardous and can cause damage to the
equipment.
Do not make or break external connectors or connections while the
Optima vT is switched on.
The component to be tested, and the air supply line to the Optima vT
must be free from water or liquid residue before testing; otherwise,
damage may be inflicted on the sensitive transducer within the
instrument.
Operation of this product outside of the manufacturer's instructions
may impair the protection provided by the equipment.
This instrument is capable of supplying high-pressure air. Before
commencing any component tests, ensure that the system is guarded
to local health and safety standards.

Section 2: Introduction
Overview
The Qualipak-770 is an easy-to-use leak testing fixture used with Uson’s Optima vT Leak
Tester to perform seal integrity and leak testing on packages/parts for the food, medical,
and pharmaceutical industries. See Figure 1.
The Qualipak-770 Packaging Test System instructions are outlined in two manuals:
• Qualipak-770 owner’s guide
• Optima vT’s owner’s guide (document# 660012)
You will need to reference both manuals for configuring and operating the system.

How it Works
The Qualipak-770 Package Test Fixture is designed to integrate with the Optima vT Leak
Tester to test the integrity of air tight packages/parts by performing a Vacuum Force Decay
test on the various packages/parts. The test part is loaded into the test fixture. The
operator selects the appropriate program for the part to be tested, then selects the start
button on the test fixture; the test automatically starts. During the test, the part under test
is subjected to a vacuum supplied by the Uson Leak Tester. The vacuum level is regulated
by the Optima Leak Tester, and during the test, the Qualipak-770 feeds back a signal
from a load cell to the Uson Leak Tester. The Leak Tester program then differentiates
between a good and bad part.

Getting Started
Note: Conduit can be threaded through either side of the test
chamber.
Perform the following steps to get your system ready to use:
1. Unpack the Optima Package Test Fixture and the Optima vT Leak Tester.
2. Turn the QUALIPAK-770 upside-down and place on a sturdy workbench. Then
remove the fixture’s bracket by unscrewing its 2 screws. See Figures 2 & 3.
3. Connect the vacuum connector to the vacuum connector inlet. See Figures 2 & 3.
4. Load cell plugs left and right. See Figures 2 & 3.
5. Reassemble bracket.

6. Turn the fixture upright, and then remove the two transit screws. See Figure 4.
Figure 4: Transit Screws
7. Connect power supply to the Optima vT’s 24vdc input. See Figure 5.
The systems power supply must be connected to an
earthed (grounded) power supply of 90 - 260V, 50 - 60Hz. Only
personnel trained to avoid the risk of electric shock should remove
the covers on the equipment. The power supply to the equipment
must be switched off and disconnected before removing any covers.
Do not make or break external connectors or connections while the
system is switched on.
8. Connect the positive pressure to the Optima vT’s air inlet port (optional)
See Figure 5.
9. Connect serial communication and power cables to the printer (optional).
See Figure 6.
10. Connect main inlet to power supply unit. See Figure 5.
11. Turn the Optima vT power On. See Figure 5.
12. Connect specified air supply, then turn air On to the system. Unit will go
through a boot-up sequence.
