Feature :

     TEC-12P is the primary high-capacity batteries for testing and development.   The main limit indicators:   It can detect the maximum capacity: 500AH   Maximum power of 200W!   Current range of 0.5 ~ 15A!   Highest detection voltage 50V, the radiator and the battery is connected, operate in a safe voltage.   Current error: full scale <0.5%!   Description: TEC-12P battery capacity meter has the following characteristics:      1. The coding switch (shuttle) operation, convenient and simple, beautiful appearance.      2. Current accurate, current full scale error is less than 0.5%.      3. The integrated temperature sensor, 40 ° C or less without turning on the fan; 50 ° C above the fan turned on; 70 ° C lower than the current automatic.   4. The maximum connection voltage 50V, off voltage can be adjusted between 0.9V ~ 50V, step 0.1V.   5. Press the current setting of the start of discharge, when the measured voltage is higher than the cut-off voltage of 0.1V, start measuring instrument automatically adjust the discharge current; in the measured voltage is higher than the cutoff voltage of 0.05V when inspection, measuring instrument again automatically adjust the discharge current; through 2 times to automatically adjust the current final cut-off time for the current setting is about 1/3 ~ 1/2, and discharge faster, more thoroughly!   6. The battery current is low, the detector can be set to automatically adjust the current until the battery is able to meet the actual current setpoint. When the actual current is less than 40% of the set current detector off discharge.  7. 12VDC power supply interface 5.5 * 2.1 (inside is outside the negative), requires a current of about 300mA.  8. After the test is complete audible alarm.  9. The maximum detection capacity 500AH. 10. The outer barrier access port, when the demand for power exceeds 100W, can access external resistance to increase the discharge power. Tester numerical display is the use of four digital tube. 5 LED lights corresponding to five values ​​displayed are: capacity, measured voltage, turn-off voltage, current and temperature. Various rotary switch to switch the display. Wherein the capacity of the unit is AH, four significant figures; Voltage in volts, three significant figures show ends with a U; Current units A, four significant figures; Temperatures are in degrees Celsius, three significant figures; How to set the discharge current:        Rotary switch to the "current" display mode, this time showing the current set, press the switch in this state, "Current" LED lights flashing, the other LED full light on the current setting mode is entered, then that is the rotary switch resizable current, clockwise increases, counterclockwise to decrease. Then press the switch setting is complete, exit the current setting mode. Simple operation, the hand that will. The minimum step size between 1A ~ 2A is 0.1A; 2A above the minimum step size is 0.5A. After adjusting this parameter will be stored in the detector, power will be maintained. Detection can also be carried out to adjust the current. How to set-off voltage:       The same as the current setting method. Rotary switch to the "off voltage" display mode, this time showing the set cut-off voltage, in this state, press the switch "off voltage" LED lights flashing, the other LED full brightness, representatives to the cut-off voltage setting mode, in this case the rotary switch to adjust the size of the cut-off voltage, clockwise increases, counterclockwise to decrease. Then press the switch setting is complete, exit the setting mode. The minimum step size is 0.1V. Detection can also be carried out to adjust the cut-off voltage. After adjusting this parameter will be stored in the detector, power will be maintained. Instructions:   1. Connect the battery to be tested, in accordance with the directions port access "battery access" side, if you need to access external resistance, the "outside blocking access" port access.   2. Set the turn-off voltage. Turn-off voltage is recommended as follows:   3. Set the discharge current. This current is the maximum discharge current, if the power exceeds the limit parameter detector, the detector will automatically adjust.   4. Start:    1 Start: Under the "capacity" display mode, press the start switch, then switch that is suspended in the stalls start measured voltage shows the open circuit voltage, in the case of access to external resistance situation should start in this manner;    2 Start mode: Under "measured voltage" display mode can also be started by the switch, the measured voltage start this way shows the line voltage.   5. tests are complete: After flashing digital display, LED lights are no longer flashing. The final volume will be displayed on digital tube. In any mode, press the switch for 2 seconds to clear the previous test results.   Round display function: In the "temperature" display mode, press the switch enters Rotator state. Each parameter display stay three seconds, was the order of the capacity of the wheel - the detection voltage - off voltage - Current - Temperature - is now displayed in any capacity ............. press the switch to the state was the end of the round.  Precautions: Please do not touch the bottom of the test circuit board components. First, to avoid burns, and second, it is possible to cause the device reset, thank you! Description of works:         Constant current control technology, the battery discharge current is always set a value, not with the battery voltage varies, if the internal resistance of the battery is too high, the discharge current up to less than the set value, this detector will automatically adjust the current.        Microcontroller circuit discharge time cumulative basis. Final measured capacity. About measurement accuracy:    Voltage measurement error: 1%, this error on the battery capacity measurement error is very small.    Setting the error current: full scale error is less than 0.5%.    Capacity measurement error: <1% package : 1pc module as picture show
