Specification - Tenma 72-2650 User Manual

• If the display speed is slower after average sampling time is enabled - this is normal
if average sampling is carried out more than 32 times. You can reduce the intervals
of average sampling.
• Waveform display in ladder shape - this is normal. The reason may be the
horizontal time base range is too low. If the display type is vector, the connection
between sampling dots may produce a ladder waveform. Set the display type to dot
to solve this issue.
