Care and Maintenance
The LT51 is designed to be maintenance free. Treat it with care to ensure the
best performance. The suggestions below will help you to fulfill the obligations of
the warranty and enjoy the tester for many years.
Avoid rough handling
Although the LT51 is designed for use in a rugged environment, avoid
dropping the tester. If you must ship the tester, use the supplied soft bag.
Clean carefully
The plastic casing for the LT51 has a finish that should retain its durability
for many years. To clean the LT51, use a soft, slightly damp cloth. To
remove any stains, use a mild soap. Never use detergents, solvents, or
abrasive cleaners on the tester.
Battery
The LT51 uses three AA size Nickel Metal Hydride (NiMH) or Alkaline cells.
Typical life of the NiMH cells is two years. Use Alkaline cells only when the NiMH
cells are discharged and the AC adaptor is not available. Always replace
Alkaline cells with NiMH when available.
Remove NiMH batteries if the LT51 is going to be stored without use for 6-
months or more. Always remove Alkaline batteries from the LT51 during storage.
To change the cells:
1)
Disconnect all cables from the LT51.
2)
Turn battery tube cap ¼ way anti-clockwise using a screwdriver or coin to
release (cells are under spring tension and may forcibly eject when the cap
is removed).
3)
Remove the old cells.
To install new cells:
1)
Insert cells into battery tube observing the correct polarity (-ve end in first).
The LT51 is protected against incorrect polarity insertion of the batteries.
2)
Push and align the bayonets of the cap with the slots of the tube, then using
a screwdriver or coin, turn ¼ clockwise to fasten.
