First, use the following method will be described in a summary manner 2Wire, the method is applicable to a variety of more than 5V battery discharge.1, will be transferred to the upper left jumper product 2Wire position.2, the wiring should be connected to the random sequence matching 1 / 200W aluminum resistors, screws must be tightened at, otherwise there will spark discharge process, burned terminals, then the battery test clip according to positive and negative electrodes in the battery clip on the product to work.3, after the company started work on the product, LED digital tube display the measured battery voltage by default, the product at the factory default setting of the battery discharge termination voltage of 10.5V, the default battery discharge current of 10A.4. If you want to change the current setting, you can press the button DOMN current LED indicator "A" at the flashing, then press the button UP and DOWN buttons can 1A, 2A ... 10A discharge current rapid cycling of several common design set, press "OK" button to confirm the exit, this is a fast current setting, if you want to 0.1A stepper set, you need to enter the setup mode.5. If you want to change the battery discharge voltage, but also need to enter the setup mode, the following will be introduced exclusively.6, set the mode introduced: Press "OK" button, the LED voltage in "V" at the flashing, it indicates that enter the setup mode, and then, and then press "OK" button, the settings can be transferred to different functions, depending in the following table:1. Features a battery discharge voltage is set, then press UP and DOWN buttons to increase and decrease buttons to set the battery discharge voltage value, then press the button to quickly change the setting when the voltage is less than 10V precision accurate to 0.01V, typically greater than 10V setting does not require high accuracy, for faster setting, the discharge termination voltage set stepper system becomes 0.1V, to speed up the set time.2. Function 2 is accurately set the battery discharge current, then press the button UP and DOWN buttons to increase and decrease the value, press and then quickly change, so that the results can be set in steps 3 to 0.1A function 3 is to save and exit, when you are sure that all projects set up, you can at this function, press uP and dOWN buttons to adjust the button to display the "ES-y", then press the "OK" button, you can save the current parameters and exit the setting mode, this saving is power is not lost, and if you do not save, just a temporary change in the parameters, then press the "OK" button on it.4. Function 4 is the automatic identification mode, the default is off, when you are mainly discharge 12V and 16V battery, you can turn this feature, press the button UP or DOWN buttons to adjust to after "AU-y", then press the top function Description save it 3 in automatic identification mode, when the access 12V battery, power on the product and instantly send a long a short beeps sound when access 16V battery power on the product and instantly send a long beep 2 short beeps, note that the product automatically recognizes only electric instantaneous detection, buzzer, power must be off when you replace the battery, so this mode is more appropriate to use 2Wire.5. Functional 5 whether to enable rapid detection, the default display is the F-00, said they did not enable the rapid detection, this time will be a regular full discharge detection, set to a non-zero value to enable fast detection, F-01 to F- 10, corresponding to the discharge time of 1 minute to 10 minutes, press UP or DOWN buttons to adjust the button for rapid detection time, right after setting the fast detection time, and then follow function after three operations to save and exit, product began rapid detection, detection of the elapsed time is a set time, after the end of the rapid test, the battery capacity will be displayed on the LED digital tube, fast time setting, see this manual supplement.6. The function 6 is constant resistance mode, the default is off, turn off the case, the system can automatically adjust based on the current setting PWM, making the discharge current is equal to the set value, and thus is constant, according to the UP or DOWN buttons buttons to adjust to "Cr-y" after the 3rd and then press the function described above, save and exit, this feature is enabled, the above constant feature automatically lapse, the current set value is invalid, the discharge current will depend on the battery voltage and external discharge resistor, the specific calculation method is also detailed supplement.7. After the setup is complete, press the "OK" button, the indicator "RUN" will be lit, indicating that the battery begins to discharge, this time, the current after a few seconds, you can reach the set value (except for constant resistance mode), At this point, press UP button to switch display various parameters, if you want time to 3 seconds of each round of the significant parameters, you need to press the up button, wait for the buzzer sounding cry, I entered a round display mode, press and hold again UP button to cancel the round display function. Here also need to note that when the number of security and capacity is the cumulative amount of time, so we put the display capacity, LED digital tube is flashing decimal point indicates the number of security already is being metered discharge, LED digital tube blinking colon is accumulated discharge time.8, as the discharge proceeds, the battery voltage continues to drop, when a conventional full discharge detector, when lowered smaller than the set below the discharge termination voltage, the product can automatically stop the discharge, and if the rapid detection mode is enabled, will after a set time to stop discharging the battery and automatically calculate the estimated capacity, while digital LED flashes and the buzzer two kinds of reminders to remind you to view the test results, press any key to stop the alarm buzzer, then press the UP button you can click to view individual measurements.9, when viewing the measurement results, transferred capacity "AH" display mode, press DOWN button capacity can be cleared, transferred to time "HH: MM" display mode, press DOWN buttons can be cleared by the time operation, this will be cleared automatically cleared when the machine is powered down.10. Remove the battery clip, this time the meter automatically power off, you can make the next battery test.11, if you need to measure more accurate determination of lithium batteries or smaller battery voltage can be used to measure 3Wire way, you need to provide products supporting the use of DC5V power 3Wire, or self-5V ~ 30V power adapter for separate power supply products, methods of operation as described below.12, will be transferred to the upper left jumper product 3Wire position, 5V power supply is turned on, then the instrument display. Product reference method of operation from 4.2 to 4.9. Special attention is required to use 3Wire way to connect aluminum resistance and power adapter, then you can set the parameter value, and then connect the battery test measurements, replacing the battery, when you need to manually clear the security number and time.
