<p>That has the same meaning with 甜甜. But it is not a formal style. For example,  When you write  a draft, you can use it but you can not use it in some official documents. </p>

As the image above, it true that the mark means duplication of the single character ahead. It is widely used by senior Chinese born in 1950s-1970s, but not very popular now.

<p>甜Z is likely the result of imperfect OCR (optical character recognition) for "5Hz". The machine probably sees "<strong>5H</strong>" as "<strong>甜</strong>".</p>

<p>It's usually seen in Google's OCR for Chinese patents. If you need to search for original patent text for clarification, you can go to  <a href="http://epub.sipo.gov.cn/gjcx.jsp" rel="nofollow">http://epub.sipo.gov.cn/gjcx.jsp</a> and search the title.</p>

<p>This is apparently a jargon engineering term for something to do with frequency (Hz). </p>

<p>I'm guessing it might be something to do with resonance ("sweet spot"?) but I've not run into it, and neither have the two native Mandarin-speaking engineers I've asked. </p>

What's the context? It might be just a typo.

It is likely that it is the result of wrong OCR. I have seen 甜z as OCR of 5Hz before (http://www.google.com/patents/CN103848774B?cl=zh).

It could also be a partial entry from a Pinyin-based input method: tianzhen 天真 truncated might produce 甜z. Context would help…

@zhantongz is correct- I found the actual original Chinese in CN104237564A and it was 5Hz, just as you said! The so-called original was OCR'd and had the 'sweet' character, which is what fooled me. If you put this as an answer I will accept it.

This is a abbreviation.

That has the same meaning with 甜甜. But it is not a formal style. For example, When you write a draft, you can use it but you can not use it in some official documents.
