    The commonly encountered failures and their solutions are listed below. When you encounter those problems, please solve them following the corresponding steps. If the problem remains still, please contact SCIENTIFIC as soon as possible. 1. The screen is still dark (no display) after power on: 1) Check whether the power is correctly connected.
  • Page 204 Scientific 2) Check whether it is a "false wave”: when the signal frequency is very large (more than half of the sample rate), it is easy to appear a "false wave". At this point, a small time base should be set to make the sample rate more than 2 times of the signal frequency.
