LEAK TESTING
To ensure the integrity of the radioactive source encapsulation, the
Model 3450 must be periodically leak tested. For instructions on
performing the leak test, see page A–13.
LEAK TEST DATE
The Leak Test function allows the operator to enter the date of the
last leak test. The gauge alerts the operator if the leak test interval
has been exceeded.
By default, the leak test interval is set to six months, as required by
U.S. regulations. In countries outside of the United States, the time
required between leak tests may vary from six months to three
years. Check local regulations, then refer to page C–26 for
instructions on setting the leak test interval.
Until a current leak test date is entered, the gauge displays an alert
after the self-test at power up. Update the leak test date in the gauge
after each leak test.
NOTE
The Leak Test function does not replace the leak test
analysis records that must be maintained for review by
your licensing agency.
To view or change the leak test date displayed by the gauge, press
the
〈SPECIAL〉 key. At the Special functions menu, press 〈2〉 to
access the Gauge Status/Test menu. At the Gauge Status/Test menu,
press
〈5〉.
