They are not over but have been paused since Thursday to be from scratch with the tracking function.

There were again only that without this "tracking the parcel" function. greetings

I am also waiting for delivery, I will immediately process my tester instead of 9V battery will be a boost converter for this some charger and batteries from the phone. You will not need to replace the battery every now and then just need to recharge it if necessary. Because, apparently, on this 9V, he can stand it for a short time.

I have probably the same battery from the beginning, i.e. probably already from two years and still the tester shows> 9V. I use it regularly on average every 2-3 days.

I use only this company all the batteries I buy.

This is what is happening to me after a few measurements, but nothing happens.

For me, after a dozen or so (made not one after the other and after probably three tester work sessions), it dropped steadily to the level of 8.75V

I compared the working time on the Energizer digital universal meter (such as in the picture above) with the Carefur's battery (blue) - comparable. On the "red" it works much longer - I write "works" because it has already crossed the record for blue and still does not show me "LOW BAT". Frequency and number of measurements performed was similar to all batteries.

Hello, I was always pissed off with a small capacity of 6F22 and a relatively large price, I ordered Ali 9V Lion batteries, probably with a converter, declared capacity greater than the battery. Soon there will be batteries with a cartridge, then I will share my impressions. I have to make a similar pull with LR2032 batteries, I have a lot of devices with such a power supply and I always lack a free cell when stores do not work . greetings

Price at the level of 25-30% of a cheap universal meter also annoys me. I make measurements on an occasional basis, so a good Alkali 6F22 withstands the meter for over 4 years. I wonder how long it will last in the tester.

You can always buy / do it yourself, in a form loaded by USB There are also 6F22 Li-ion batteries, 8.4V

Please, report after purchase because I am interested in buying.

There is even a 1200 mA version. How do you think, how real?

Rather not enough. Capacities start at 280. These 600-700 will go away, but I have more concerns.

Or maybe I just put and test such power.

You can also do it on a cheaper 1 board: stabilizer 7809, 2 capacitors 100nF and DC Jack connector and connect it to the power supply, eg from the router.

You can also but it is not such a big cost about 3.5 PLN with ali .. plus some battery from an old phone and in such a configuration you do not need a network battery system is portable and the network only charges the battery if necessary.

It is a pity that there is no electrode logo on the tester / housing. I am waiting for the shipment, certainly the tester will be very useful.

Not necessarily, there may be stickers, pens - calipers, or screwdrivers. I got a tester to the tester, a pressure gauge.

Hello. I received information from home that the parcel had arrived (tester, sticker and screwdriver). I'll be back from work after testing and let me know what and how. Greetings. elektrodo, thank you.

The tester reached me yesterday, along with one sticker with the electrode logo, and a screwdriver, although I was counting on a caliper, because the screwdrivers gave me a lot of . Today I made the whole and (which is obvious to me ) slightly improved the "factory", i.e.: first of all, the display was immobilized with double-sided adhesive tape, I shortened the housing screws (ATTENTION! - do not tighten them too much, because the front and rear panels bend!), immobilized aku so that it does not fly inside, to the rear I stuck my feet on the panel. Thank you! Greetings.

The work was prolonged like: oh, even longer, I am testing. Coming from work I bought batteries as they were (produced this year by PANA ... C. 10.6V) four tests and Vbat = 7.8V. I connected the old about three-year old (Kodak), removed from my multimeter (8.8V) after a few ten tests, a 0.2V voltage drop. Ignoring the resistance of "own" power sources, in order to reduce the power consumption, I switched off the backlight display and here the bowel, with 13mA decreased to only 12mA. I promised, I write but the main reason was this statement:

I put on (screwed) rubber feet on these protruding screws. Currently, I have a 9V power supply connected to further tests but then, afterwards. Greetings. PS Grandfather, this is "GADGET" but "trusty" grandson told me so. End of summer. I think I will stop the tester at home to not part with .

Is it possible to get such a display somewhere cheap? My exeplarz did not survive the folding (the black tape securing the connecting tape was peeled off), so that the screen remained dead.

Does this tape protect anything (if so from what and in what way) or is it used to remove the screen protecting foil?

You need to ask yourself whether it is worth buying the display itself, or adding less than 10 PLN and buy the whole tester and have a sample copy, as a dose, etc.

You'd better buy it all.

I did so at first, but I only have legs with a diameter of about 24mm, so they stick out a bit and are otherwise quite high (about 15mm), which seemed to me a little aesthetic. I have a lot of them, so I used them and it looks better to me. Temporarily, I power the device, visible on the photos aku 200mAh and who knows if it will not be this way? I have a little bit of them and despite their age (it's about 7 years old), they stay well. After about 30 minutes of testing, the voltage from 8.9V, dropped to 8.75V, so it's not bad.

So I repeat it after Gulson: just after carefully removing the foil tester, attach / stick the display! It is on the first and second page of the story. Greetings.
