[[File:DC_Load_60W_Top_View_Annotated.png]]

* Operating modes: single mode constant current (CC) 
* Discharge current
** 200 mA (min)
** 9.99A (max) in steps of  0.1A or 0.01A 
* Discharge current maximum error : 0.7% -0.01A 
* The maximum capacity test error : 0.5A 2.5%, 2A 1.5%, 5A and above 1.2% 
* Offline ( termination ) Voltage Range : 1.0-25.0V stepping 1V or 0.1V 
* Discharge voltage : 1.00-30.00V 
* The maximum voltage measurement error : 1% + - 0.02V 
* Maximum power : 60W super power automatically limits the maximum current (for example, up to 60W when it can open 9.99A 6V and 20V maximum at the only open 3.00A) 
* Highest battery test statistic : 999.9Ah or 9999Wh, achieve value stop testing ( first value to those who stop condition ) 
* Board size : 60W 100mm * 70mm * 57mm ( fan prominent board about 12mm) 
* Positioning hole locations : 60mm * 88mm diameter 3.2mm 5mm pedestal already installed. 
* Fan control : intelligent fan control ( according to the radiator fan can be infinitely variable automatic temperature ) 
* Protection: Overheat protection "otP"; transient overpower protection "oPP"; overpressure protection "ouP"; reverse polarity protection; power supply voltage abnormal protection.

== Setting Digital Illustration ==
 
=== Electronic Load mode ===

# Turn on the power supply 12V
# Unit will boot into electronic load mode, ensuring in a stopped state
# "RUN" does not light, otherwise the press of the start-stop switch to turn off the load
# Connect the UUT test to the (P + P -) pins - pay attention not to take the wrong polarity
# Adjust the current and lower voltage knob
# Press the knob to change the setting digit, digital middle two digits to the right of the indicator and digital indicator VA simultaneously determine the current set position . 
# Press the start-stop switch , load will be applied, 
# "RUN" lights
# Upper display the actual input load voltage
# If the voltage drops below the set limit voltage " RUN " LED flashes and short beep alarm buzzer beeps
 
=== The battery capacity test mode === 

# The test battery should be fully charged
# Set the tester in the battery capacity test mode
# Connect the battery current line to P + P- positive and negative terminals
# If you use four-wire clamp test, connect the four-wire interface to the positive and negative to the V + V - port. 
# Turn the knob to set the discharge current and discharge voltage
# One press after setting the start and stop switch , a battery tester and a first line detection, automatic identification 2-4 line ( 2-wire line identification presentation JS-2,4 identification JS-4, if an error please stop the test and check the wiring ) , then enter the test , if the fault code appears , refer to later explain . 
# The testing process will round up digital noticeable battery voltage , current , and the current discharge capacity Ah discharge energy Wh, when the discharge end ( battery voltage is below the set voltage ) , the tester displays the data stays in Ah and blink rapidly , with bee shortness buzzer alarm. 
# Press the start and stop at the knob or switch to stop the alarm , you can turn the knob to view the battery discharge data , including discharge capacity Ah, Wh and discharge energy platform voltage V, start-stop button is pressed again, clear the data back to the initial setting interface before testing the next section batteries.

=== Additional information ===

# Battery test process can adjust the discharge current, if you need to re- adjust the termination voltage, you can pause by pressing the switch at the start and stop the discharge modification ( pause discharge will return to the settings page, this time discharge data is not lost, if necessary, you can long press clears the data until the start-stop switch 0.000Ah). 
# Tester automatic storage can record setting parameters , and record all parameters and status at the end of the test process and test power failure alarm status , re- transmission of all automatically restored.

== Fault protection codes and meanings ==

* Err1: ultra-high capacity test the battery voltage. 
* Err2: battery voltage is below the set termination voltage is not connected to the battery or the battery is reversed. 
* Err3: line resistance is too large or the battery can not afford to set the discharge current. 
* Err4: circuit failure. 
* Err6: working power is inappropriate , use a standard 12V power supply , and the supply current is not less than 0.5A. 
* otP: overheating protection. 
* Ert: temperature sensor failure or the temperature is too low. 
* ouP: ultra-high voltage electron -load mode. 
* oPP: under ultra-high power electronic load mode instantly.
