The new digitally controlled dc load ZL1100 is also cool. I always hated the trimmer pot of the ZL1000.
edit: heh, you just added the ZL1100 link, oh well
edit2: Franky also has it listed on his ebay store I’d like YZXStudio to supply it with a serial logger program much like the EB tester software that is able to program their loads.
The ZL1100 looks interesting, but is sold out. I have a couple of the ZL1000 load and all is the version without trimpot, the only one with trimpot I have is the one I reviewed and I usual do not use that one.
Ok, I got few questions now, seems my unit is not able to set some of the parameters I have available in the options, to be more precise I cannot set any of the option from 14 to 19 (14 and 19 included) which are
14.Trickle charge current
15.Trickle charge delay
16.Over current protection
17.Under voltage protection
18.Over voltage protection
19.Over temperature protection
Withouth these the meter is just a normal meter with higher resolution
My fw is 3.30 Y1273 could someone check in his for me? Also if someone has the English manual and could share it somewhere would be great...
Now that i have my zy1273 i can say i like yours much more.
Anyway, if you have a decent multimeter and a USB plugs with terminals you could measure current and say which one is off.
Otherwise you could roughly say it by attaching an Android phone (i don't know anything about ios) with an app called Ampere or another called Accubattery, which measures fairly well (considering that is just an approximation) how much current it is flowing through the phone. This at least, considering the big difference in numbers will tell you which one to trust and which one recalibrate (if possible)
I don't know if yours can recalibrate i'm pretty sure 1273 is not thatconfigurable (pretty disappointed by it)
I own multiple YZXStudio's meters, which were all calibrated when I got them, and they all show the same difference between load and meter. I believe they can be recalibrated. Good thing I bought mine at Franky's eBay store, he's usually really good about these kinds of things.
I meant user recalibrated, let's say you have proper DMM (like a top of the line Brymen, Fluke, Agilent) or a bench type you could use as reference, also a bench type Electronic load, you could recalibrate your own like some other stuff allows you to.
You don’t need a lab power supply for that. I bet one of your many usb chargers has enough juice to put out 2.7 amps. Just put the ZY1271 in between the charger and load like in your video to check the current. There’s a Curr ref menu option in which you enter the current you see on the 1271.
