Electrical Leakage Problems

Electrical leakage problems are difficult to locate and correct. An additional labor charge will be made for such leakage problems. Such charges will be established at the time based on the degree and type of leakage problem. Most such problems are related to past methods of, and cleaning materials used to clean the controls, switches, tube sockets and the chassis. Many methods and cleaners left residue that has caused electrical leakage. The problem can show up at any time due to new cleaning (evern when using zero residue cleaners) or due to moisture/humidity. Chemicals are often obsorbed into the switches and controls and on the wiring and under certain conditions become active causing leakage when testing tubes.

Electrical Leakage Exception Policy

Over the years many testers have had their switches and tube sockets cleaned with may different types of chemical cleaners. Many cleaners left a residue, or created an electrical leakage path. Over the years mixtures of different chemicals have combined to create other compounds with electrical leakage properties, and sometimes they are absorbed into the phenolic switch wafers. In such a case often the removal of the leakage is difficult and vary time consuming, requiring many hours of labor, and the use of large amounts of a high quality non-residue cleaned and special drying out processes after the cleaning. Due to the complexity and difficulty and additional labor to remove the leakage, I have had to establish an additional labor charge to clean and remove leakage from switches and tube sockets. This policy is only implemented when normal cleaning processes do not work or where one of the main problems/complaints/symptoms are leakage between tube elements when no tube is under test or where many tubes tested seem to show leakage or shorts where there is no actual shorts or leakage in the tube.

Tube Socket Replacement Policy

Tube socket replacement is a time consuming process! Therefore to keep service labor rates down I have included the replacement of up to two (2) tube sockets (in the flat fee labor rate) if required in each of my repair/calibration categories. Any additional tube socket replacements will be performed at an additional labor fee of $5.00 per socket plus the price of the socket. Tube sockets are first tested and then tightened and cleaned and only replaced when it is clear that a socket is bad.

Meter Repair Policy

Meter repair can take as much time, or more time than it takes to repair a tube tester in some conditions. The work is also delicate. Not all meters can be repaired. Many meters are now beginning to deteriorate and becoming unglued literally, and it's getting worse over time. Currently about 75% of meters with problems are able to be repaired, or cleaned. Meter repair has a separate repair labor charge. However, meters can not be returned to new condition and most repairs will only prolong the continued deterioration of the meter over time. It is not possible to determine how long the meter will last after repair. It may last several years or only one or two years. There is also some risk that the meter may get worse or become damaged in the process of repair. While this is rare it is a possibility in a small number of meters.
