Thermo Scientific TVA-1000B Instruction Manual - Geotech ...

MI 611-185 – June 1996
Display Menus
Once the countdown is complete, the TVA-1000B display will freeze on the reading to be
logged and indicate if it is a leak (i.e., if the reading of the active detector exceeds the indicated
leak rate). You will be given several options:
If you choose “Sav”, the TVA-1000B will store the reading in memory (replacing any previously
logged readings for that Tag) and proceed to the next component record in the route. If
you choose “Again,” the TVA-1000B will repeat the countdown and obtain a new reading. If
you choose “Exit” the TVA-1000B will return to the previous screen.

If the reading obtained during the logging interval exceeds the leak definition, the
TVA-1000B will indicate that it is a leak by printing “Leaker!” If you wish, you may record
what part of the component is leaking and what action was taken as a first attempt at repair.
Choose “Repair” instead of “Sav” and the TVA-1000B will proceed to the Repair menus:
FID 100.0 ppm

Repair Method: N/A
[Select leak source]
-Select repair mthd
-Exit
The two lines below the reading show the currently selected leak source and repair method.
Choosing “Select leak source” will allow you to record what part of the component is leaking
by choosing from a list of leak sources (Valve Bonnet, Compressor Seal, Downstream Flange,
Valve Packing, Pump Seal, Upstream Flange). Choosing “Select repair method” will allow you
to record what method was used for the first attempt at repair (Place Cap, Gun Pack Valve,
Place Plug, Repack Valve, Replace Gasket, Replace, Seal Job, Steam Seal, Tighten Bonnet,
Tighten Cap, Tighten Flange, Tighten Packing, Tighten Plug, Wash Seal). Choosing “Exit”
will return you to the previous display.
If you choose a leak source and repair menu, be sure to select “Sav” when you return to this
menu so the reading and repair information will be saved in memory before proceeding to the
next component record.
