Latest up date firmware for Tenma 72-8725, Farnell o/c 183-6063 ( 4/3/11)
Trivial bug: Help divides the text into lines, but it breaks words anywhere instead of at a space. e.g. MEASURE is used to measure parameter of waveform, this DSO can measure27 parameters of the waveform. The choice menu of measure kind include voltage kind and time kind.

Issues with user manual, please see below questions and answers and please find attached new user manual.
- 1) The manual on p. 72 in paragraph 1 under ‘Instructions:’ reads: “A stored reference waveform can be recalled with … (reference waveform, P 32). For specific steps see the REF instructions.”
Could you please point the location of the mentioned instructions? I cannot find anything on ‘reference waveform’ on p 32, albeit the statement cited above.
It should be P44 instead of P32. Sorry for this type mistake. Please refer to updated manual per attached.
- 2) On the same page, under ‘Note:’ it is stated there are two formats for exporting a waveform to USB. I have not found any reference to setting the format of data for saving in the scope’s internal memory. Could you please explain how to retrieve data from the internal memory without merely displaying it as a reference?
For the waveform saved in internal memory can’t be exported as data. If you want to export data please choose export to USB CSV format.
