2. Power switch: Turns on or off the instrument.
3. Power input*: Connect to a proper AC source. Only use a non-noisy power
source. Lower quality gasoline power generators can induce high levels of
noise which can affect measurement accuracy.
4. Ground post: Before connecting the CTT instrument to any other cable/
equipment, make sure the ground post is earthed properly using the provided
ground cable.
*Note: 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.
