Description
Power supply voltage: DC4.5-6V (micro USB interface)
Working current: less than 70mA
The discharge voltage: 1.00V-15.00V resolution 0.01V
Termination voltage range: 0.5-11.0V
Supported by current: the maximum 3.000A resolution 0.001A
The maximum measurement error voltage: 1%+0.03V
The maximum measurement error of current: 2%+-0.010A

The maximum battery capacity range:
9999Ah (1Ah=1000mAh) value of the larger through the decimal point shift switch,
when lower than 10Ah shows X.XXX, above 10Ah show for XX.XX, and so on.

Board size: 50mmX37mm

Note:
this circuit in order to improve the voltage measurement accuracy,
specially designed DC bias,
when the terminal is what all don't pick will display a small voltage,
does not affect the actual measurement,
if you are short connected with the input terminal (absolute 0V)
will display 0. To understand the principle can consult the superposition theorem in electrical engineering.

Method of use:
1> measured battery should first fully charged.
2> connected with the tested battery anode to cathode to input input positive,
negative, is not reversed (with load reverse may damage the circuit)!
Connects the load to the output positive electrode and the output negative electrode,
through operating power to the tester micro USB
(not available on desktop or laptop USB power supply),
the display of battery voltage.
3> direct start test only need to press the "OK" button,
the tester can automatically set according to the battery full charge voltage suitable termination voltage flicker,
and will display 3 times after the start test.
Need to set up the termination voltage need only when
the battery voltage display state press "+" or "-" key modification,
termination voltage display for P at the beginning, behind represents voltage value,
resolution 0.1V, set up after the press "OK" to start the test.

4> testing began after the tester will electronic switch connected to the control of the load
, the testing process data are displayed in the release capacity (Ah),
the current discharge current (A) and a battery voltage (V) between the round.
When the battery voltage reaches the set after the termination voltage tester,
cut off the load control switch, display the data stays in the capacity (Ah)
and the corresponding indicating lamp above and with rapid blinking,
the actual discharge capacity of the battery capacity is displayed,
press the "OK" can be terminated flashing make stable data display,
again by pressing the "OK" the button back to just power on state can replace the battery test the next day......

The error code and meaning:
Err1: the battery voltage higher than 15V
Err2: the battery voltage is lower than the setting voltage termination
Err3: the battery is unable to withstand the load discharge current resistance is too large or line
Err4: the current is too large (current is more than 3.1A)

Two calibration operation (operation after self calibration, represents give warranty):
At the same time, press three keys to the tester is energized,
enter the calibration mode, the first display calibration record number of times
after entering the formal calibration sampling procedures to display the 0u0A,
then the short connection input positive and negative pole after press the "OK" button to complete the display,
J10u, between the input positive and negative applied 10.00V standard DC voltage after the
"OK" button is pressed after the show, J2.0A, to the output negative electrode (inflow direction)
and the input cathode (outflow direction) under 2.0A constant DC
current to press the "OK" button to complete the calibration.
Tester will pre audit of the calibration data, if the calibration data is reliable,
it will in turn show 4 calibration number after the exit,
if the pre audit that data is not reliable,
discarding data exit.

Perfect
Size: 9.25”, Color: black-4 pack, Size: 9.25”, Color: black-4 pack
very nice brackets..very sturdy. Fits a 1x10 board perfect. Comes with everything you need and a.cool little level also. I loved them.so much I bought another pack and decided to add more shelves for my plants. It was easier to mount the shelf to the bracket then mount the whole shelf. Holds almost all my plants some are pretty heavy.

Well made brackets
Size: 11.25“, Color: black-6 pack, Size: 11.25“, Color: black-6 pack
These are nicely manufactured in that they are all exactly the same (with no variations) and with nice countersunk holes for the provided black flat head wood screws. I used a stained 1x12 #2 whitewood (Eastern Pine) from Lowes for the shelves. With these brackets solidly installed into wall studs at 32" on center (every other stud) the 1x12 shelf will easily support a heavy book load. I like the look better than the brackets that have the vertical leg below the shelf. It looks a lot cleaner. It is probably inevitable that your stud layout will result in a bracket or two needing to be installed between solid wood studs. In this case, do NOT use the sheetrock wall anchors provided with the brackets as they will pull out of the wall under an appreciable load. Instead, get some "Snaptoggle" toggle bolts and replace the provided bolts with #10-24 x 1.25" flat head machine screws in black. These toggle bolts are incredibly strong and easy to install. I am adding a postscript to my review regarding bracket spacing recommendations. With a heavy book load, the 1x12 shelf boards don't sag with the brackets spaced 32" apart, however I have found that the brackets themselves are overstressed by about 30% (they are only rated at 80# each.) Heavy books weigh up to about 36# per lineal foot so the maximum spacing of the brackets should be 24" apart. At 32" apart, they won't pull out of the wall if they are fastened into studs but they will sag a little bit back to front under this load. So I added additional brackets in between the installed brackets and now they are 16" apart at the heavy book shelf. The load on each bracket is now less than 50# but they STILL sag about 3/16" from back to front when loaded with books! No danger of structural failure and the sag is not really noticeable.

nice brackets
Size: 11.25“, Color: black-8 pack
loved the look of these brackets with wooden shelves, brackets seem to of good quality and holding up well. only issue is one bracket was slightly out of spec. but besides that they work awesome and good price.
