FIG. 1-1 TRANSDUCER TEST SET (TTS) - BLOCK DIAGRAM
Baery Operaon
The TTS can be operated using an AC line power source or from its internal
rechargeable baeries. No switching is necessary since AC line power is always connect to
a built-in baery charger thereby providing a charge whenever connected to power. Maxi-
mum charge rate is achieved when the TTS is o.
Baery power for the TTS is supplied by two (2) sealed solid gel rechargeable baeries. The
baeries are designed for connuous charging without damage. Baeries should be kept
fully charged. Under nor- mal operaon, the TTS will operate in excess of 4 hours with fully
charged baeries.
Charge life is directly dependent on the power used which is established by the test require-
ments. When tesng requires high force be supplied to drive the test transducer (due to
heavy xturing or transducer size and/or due to high test levels) the charge life will be
shortened.
CAUTION A COMPLETE DISCHARGE CAN CAUSE BATTERY FAILURE.
A protecon circuit switches the TTS o automacally. When this occurs, the TTS must be
connected to AC power to acvate its charger right away. Under normal condions baeries
will obtain a full charge aer (8) hours charge me. If deep discharge occurs, one or more
days may be required to reach full charge.
Special Handling and Storage
The internal baeries are sealed and should provide long term service under normal operat-
ing condions. They are securely mounted heavy duty brackets so that no damage can occur
from shipping or normal transportaon. No special handling should be required.
