Interfaces Chapter 8
• Use a common ground for both the instrument and the computer. Using differ-
ent ground circuits will result in a potential difference between the instrument's
ground and the computer's ground. If the communications cable is connected
while such a potential difference exists, it may result in equipment malfunction
or failure.
• Before connecting or disconnecting any the communications cable, always
turn off the instrument and the computer. Failure to do so could result in equip-
ment malfunction or damage.
• After connecting the communications cable, tighten the screws on the connec-
tor securely. Failure to secure the connector could result in equipment mal-
function or damage.
