NDB Technologies CTT Series User Manual page 5

• Do not attempt to disassemble the device or its accessories. Only qualified
personnel can perform maintenance.
• Prior to using the CTT, a careful inspection should be made to ensure the unit is
free from any contaminants and that there are no apparent physical damages.
• Do not use the device while driving.
• Do not place the device or its accessories in containers with a strong
electromagnetic field.
• Do not use the device in an environment with flammable gas, such as a gas
station, or put the device in a high temperature place.
• The CTT's internal circuits are set from the factory for either 115V or 230V
input voltage and cannot be changed. Therefore, it is important to keep the
fuse socket orientation as set by the factory and only use the proper input
voltage. Using improper voltage can permanently damage the instrument.
• Keep the device and its accessories away from children.
• High-voltage discharges and strong electric or magnetic fields may interfere
with heart pacemakers. If you have a pacemaker, obtain medical advice on the
possible risks before getting close to the energized test set.
• The ground connection must be the first made and the last removed.
• Never connect the CTT to energized equipment/transformer.
• Never disconnect the test leads while performing a test.
• Always disconnect test leads from the power equipment before disconnecting
them at the test set.
• To remove the test clamps from the transformer's terminals after a completed
test, it is strongly recommended not pull on the cables themselves. Pulling
the cables can possibly weaken the internal structure of the cable and cause
intermittent readings. Instead, it is recommended to remove the cable by
opening the clamps first.
