the CT100's internal menus. This button also activates on-screen help when held down while
pressing other buttons.

11) BNC connector. This connects to the cable you wish to test. Be sure to properly ground the
cable before connecting it to the BNC connector in order to prevent electrostatic damage to the
CT100's sensitive sampling circuitry.
CAUTION: All static charge must be drained from the cable to be tested prior to
connection to the BNC connector (11). This is done by shorting the center
conductor of the cable to the sheath / ground return. If this procedure is not
followed, the sampling electronics can be damaged and you will void the
Warranty.
12) Host USB port. This USB (V1.1) connection can be used to interface to a client USB device
such as a barcode reader, keyboard, or thumbdrive.
