Tenma 21-10120 problem

[jdangel38]

Hi, hoping for a little help from the AK community. My Tenma 21-10120 soldering station somehow switched to Celsius temperature output. I've long ago discarded the manual and can't figure out how to change it back to Fahrenheit. I'm having trouble downloading one anywhere. I can email Tenma and ask for an emailed copy of the manual, but since that would probably end up taking a few days to get a response, I'm hoping someone might be able to help me out. I looked on quite a few sites, and could not find a copy, except on one site, but it would not let me download the manual. Any help would be greatly appreciated. Thanks!

Thanks for the link, but I've already been doing this.
I want to fix the problem instead of using workarounds.

Thanks for the link. I had seen this, but unfortunately the controls are different and trying similar things didn't work on mine. Thanks though!

Another link.
Tenma is some generic brand, and apparently a lot of the same equipment is sold under different names.
So here is a link to a same-looking device. Note: its is different languages find English language somewhere in between. There is something about the degrees switching in there.

That worked!! Problem solved! I had Emailed Tenma but not received a response, and would never have known to look for another brand!

Guess Tenma is a reseller brand only.
There was another thread about some all-in-one frequency counter/multimeter/power supply the other day, which I recognized as I had such myself.

It also was a Tenma.

Already then I knew the thing I had (a predecessor) was one Voltcraft and a very the same Metex, and apparently the thing existed as Tenma, Unisource and SJ electronics too.
And now "toolcraft"..

What was the final trick that worked?

What was the final trick that worked?

It's on page 29 of the link, essentially a tricky on-off-on while the right button is pushed sequence. Would never have thought to do that!

Yeah, I have a couple of small digital clocks that have that sort of way of setting function. A RPITA if you ask me. Glad that you got what you needed. My Tenma is at least 5 years old and has held up well under moderate use. If I was a daily user, I probably not picked it for my station. I have no complaints up to now.
