content: For sale is my TekScope THS720A. I have owned this for several years and have done the following to it:Updated to a 720PNew CCFL lamp.Added the option to use regular C cells.It does have a little DC offset when first turned on, but settles back to it's SPC calibration as it warms up. It has always done this.I replaced the opto couplers, which improved it, but still some drift from cold to warm. Optos bought from Mouser, so I assume they were NOT fakes. I'm not sure now how much is normal, but it was never an issue to use it. Passes ALL self tests, version 1.16 firmware.Original battery is dead, but included as a template to make another OR just use 4 C Cells like I did. Includes power supply AND serial cable.It never came with probes and none are included. I just used my probes from my bench scope when I needed it.Why am I selling it? I got a Fluke 199C! Wouldn't you?Asking $125 SHIPPED. If you want a fully ISOLATED scope meter, this could be a good buy.

Also it never hurts to say what form of payment you accept. You could even fix that sideways photo.What does the THS720P upgrade add?

content: QuoteThe 720 "P" option is Power analysis. A feature often discussed here, but I personally don't need. Gives you harmonics and such. Apparently an actual 720P goes for substantially more, but it's just a small hardware mod in the 720A to change it.And I have no idea why the first pic is on it's side, it is correct in my image viewer....... And so is this one.... what the hell?Sorry about that! I took ALL the pictures in the same orientation, why are some rotated after uploading?

content: Quote from: Runco990 on February 24, 2025, 07:55:50 pmThe forum doesn't support JPEG orientation flags. My guess is that you edited and resaved the images that have the correct orientation, since they are also smaller.

content: Thanks for the reply. I am on Linux mint, since I will be listing more test gear, any suggestions as to what image format I should be using?I have also had troubles finding a moron-proof easy to use image resizer, since my phone does not give me that option. I wish it did, like my old one.Appreciate the help.

I don't know the best Linux image resizer, sorry (I use Photoshop). There is probably some phone app you could use also, wish I knew which one
