SAFETY SUMMARY
Follow Exact Operating Procedures
Any deviation from the procedures described in this operator’s manual may create one or more
safety hazards, damage the VBT-80P, or cause errors in the test results. Vanguard Instruments
Co., Inc. assumes no liability for unsafe or improper use of the VBT.
The following safety precautions must be observed during all phases of test set up, test hookups,
testing, and test-lead disconnects.
SAFETY WARNINGS AND CAUTIONS
This device shall be used only by trained operators.
All circuit breakers under test shall be off line and fully isolated.
Do Not Modify Test Equipment
Because of the risk of introducing unknown hazards, do not install substitute parts or perform
any unauthorized modification to any Model VBT-80P Test unit. To ensure that all designed
safety features are maintained, it is recommended that repairs be performed only by Vanguard
Instruments Co. factory personnel or by an authorized repair service. Unauthorized
modifications can cause serious safety hazards and will nullify the manufacturer's warranty.

Operating Procedures VBT-80P
1.0 INTRODUCTION
1.2 General Description
The VBT-80P is a lightweight DC vacuum bottle tester made by Vanguard Instruments
Company. The VBT-80P tests a vacuum bottle’s integrity by applying a DC voltage across the
bottle under test. A simple “PASS” or “FAIL” message indicates the condition of the bottle after
each test.
The VBT-80P is rugged and field-portable. It is easy to operate and requires little training for
first-time users. Operating the VBT-80P only requires connecting the test leads to the vacuum
bottle, selecting the desired test voltage, current threshold, and test time duration, then initiating
the test. A keypad with 16 alphanumeric keys allows the user to control and enter circuit breaker
test data. A built-in thermal printer produces test results on 2.5-inch-wide thermal paper. The
VBT-80P test records can be stored in its FLASH EEPROM memory. Up to 84 records (of 16
readings each) can be stored in the VBT-80P’s memory.
1.3 Functional Description
Using a voltage multiplier, the VBT-80P generates a programmable test voltage from 10,000Vdc
to 80,000Vdc in 1,000Vdc steps.
The test voltage can be applied for different time durations: 5 seconds, 10 seconds, 30 seconds, 1
minute, or 2 minutes. The current through the bottle is monitored by the VBT-80P’s circuitry
during a test. If this test current exceeds a preset threshold, the test is terminated and a test
“FAIL” message will be displayed on the LCD. The “TEST FAIL” indicator will also be
illuminated on the front panel.
The over current threshold can be programmed for 100 micro-amps, 200 micro-amps, or 300
micro-amps.
A test is considered successful if the selected test voltage was applied for the entire test time and
the test current did not exceed the preset threshold.
The VBT-80P’s LCD displays a “PASS” message along with the test voltage and test duration if
a test is successful. The “PASS” and “FAIL”” message can be printed on the built-in thermal
printer.
1.4 Furnished Test Accessories
The VBT-80P is supplied with one 10-foot long high-voltage test cable, one 10 foot long
voltage-return lead with alligator clamps. A Ground cable, power cord, and a shipping case are
also included with each VBT-80P.
Note
The VBT-80P high voltage cable can be replaced in the field. Do not remove this HV cable from
the connector except for cable replacement.

3.0 CONTROL AND DISPLAY
3.1 VBT-80P Front Panel
The VBT-80P controls and displays are shown in Figure 3. Pointing leader lines reference each
item with an index number. Each index number is cross-referenced to a functional description in
Table 2, which describes the function and purpose of each item on the control panel. Although
the purpose of these controls and the display may seem obvious and intuitive, users should
become familiar with them before attempting to use the VBT-80P. First-time users should also
review and become familiar with the Safety Summary on the front page.
