Energy: display the current battery dump energy
Battery level is shown through the five battery level grids on the LCD screen, is distinguished by the current voltage and cut-off voltage and full-scale voltage. So before test, you should set the cut-off and full-scale voltage.
Every grid stand for 20% energy, At full-scale voltage, it displays 5 grids, when comes the battery cut-off voltage it will display format 0 and so on.

Button
3.1
Backlight control
The backlight turn off acquiescently when power on, you can turn it on or off by short press the “set” button.
3.2 Cut-off voltage of the battery and full-scale voltage settings
Step 1:Long press the“SET” button for 3 seconds to enter the battery cut-off voltage and full-scale voltage setting state, then release the button;
Step 2: After entering the state, voltage area flash to display the current battery cut-off voltage
,
and use the zero battery level symbol to indicate it is the cut-off voltage setting state; then you can shot press the button to add one, long press the button can add one quickly; the range of cut-off voltage setting is 2.8 ~ 29.9V, but not more than the full-scale voltage.
Step 3: When there is no key operation more than 3 seconds, it automatically enter into the full-scale voltage setting state;
Step 4: After entering this state, voltage area flash to display the current full battery level voltage, and use the full battery level symbol to indicate it is the full-scale voltage settings state; setting method is as same as the cut-off voltage; the range is 2.8V ~ 29.9V, but not less than the cut-off voltage.
Step 5: When there is no key operation more than 3 seconds, it will automatically save, if there is no error after saving it will quit
automatically, if the value is incorrect or save incorrectly, it will display “Err SAu” for 1 second, and exit.
C.
Discharge resistance
Many user like to use resistance as a load to do the battery discharge test, there is no stipulation of the resistance value and power, you can calculate through the formula:
The value of discharge resistance=Voltage/current
The power of discharge resistance=Voltage* current
D.
Calibration
The product may be has the measure data inaccuracy or in a mess because of the interference, faulty operation or wrong wiring and so on, then you should calibrate it. The method is as following:( if you don’t have the calibration equipment or your calibration is failing, please contact your supplier)
Step 1: Cut off the power, open the back cover, short circuit the calibration point( there are two holes marked “W” on the margin of the circuit board)
Step 2: Then give it the standard voltage and current for10v/1A( for example: use the DC electrical source to output 10V voltage to the product, and the load wire a standard resistor of 10
Ω
/10W, then you can get the calibration condition.)
Step 3: Then the screen will display
“10V,1A”
flickeringly, which indicate it is the calibration state and the calibration condition is “10V,1A”
Step 4: If the calibration is successful, the screen will display “PASS” for 1 second, then exit the calibration state and return to normal, if display other information, it means the calibration is failing.
Step 5: After calibration, cut off the power and calibration point, then you can use it normally.
