D–12
Leak Testing
Unless specified otherwise by your license or state
regulations, the gauge must be leak tested at intervals not
exceeding 12 months to ensure the integrity of the radioactive
source encapsulation. Sample analysis must be performed by a
licensed laboratory only.
Using the Troxler Model 3880 Leak Test Kit (PN 102868) and
accompanying instructions, perform the following procedure:
WARNING!
Ensure that the source rod is in the SAFE position
(see Figure 8 on page 3–5).
Write the date, gauge model number, and serial number on
the sample form and label.
Remove the control panel from the gauge topshell. Locate
the yellow radiation label on the top surface of the base.
Holding the wipe disk with the tongs, wipe the radiation
label.
Turn the gauge on its side and locate the opening where the
source rod extends through the gauge base.
Holding the wipe disk with tongs, wipe the area around and
inside the opening where the source rod extends from the
gauge base.
Pack the disk, as instructed, in the envelope and mail to
Troxler Electronic Laboratories, Inc. for analysis.
Secure the gauge properly.
