Note: Some customers report that the product has data jumps, which is normal. (When using this product: After being placed in water, the data will always change slowly from the last decimal point, this is because the PH meter needs to adapt to the test environment. The data will be stable for about 1 minute when it is still, and this the final test data. In addition, if the water surface shakes, the data will also jump, so the test must ensure that the water surface is still.)

When the value is large, it is switched by decimal point shift. When it is less than 10Ah, it will be displayed as X.XXX, when it reaches more than 10Ah, it will be displayed as XX.XX, and so on.3. Circuit board size: 50mmX37mm4. Finished product size: 50mmX37mmX17mm (Length X Width X Height, including copper foot height)5. Weight of board and accessories: single board 28g (including copper pillar), two 5W ceramic resistors 9g, 50W resistor about 27g (including wire)6. Note: In order to improve the voltage measurement accuracy, this circuit is specially designed with DC bias. When the terminal is connected nothing, a small voltage will be displayed, which does not affect the actual measurement. 0V) will display 0. If you want to understand the principle, you can check the superposition theorem in electrical engineering.7. How to use:- The battery under test should be fully charged first.- Connect the positive pole of the battery under test to the input positive pole, and the negative pole to the negative pole of the input. Connect the load to the output positive pole and the output negative pole, and connect the tester micro USB with working power (not available for desktop or notebook USB power supply). The battery voltage is displayed at this time.- To start the test directly, just press the “OK” button, the tester can automatically formulate a suitable termination voltage according to the full charge voltage of the battery, and will flash the display 3 times to start the test. Need to manually set the termination voltage, just press the "+" or "-" button to modify in the battery voltage display state, the termination voltage is displayed at the beginning of P, the back represents the voltage value, the resolution is 0.1V, after setting, press "OK" "start testing.- After the test starts, the tester will turn on the electronic switch that controls the load. The test process data display will be displayed between the discharge capacity (Ah), the current discharge current (A) and the battery voltage (V). When the battery voltage reaches the set termination voltage, the tester cuts off the load control switch, the display data stays above the capacity (Ah) and flashes quickly with the corresponding indicator light, the displayed capacity is the actual discharge capacity of the battery, press it "OK" can stop the flashing and let the data display stably. Press the "OK" button again to restore to the state of just powering up and replace the battery to test the next section ...8. Error code and meaning:- Err1: The battery voltage is higher than 15V- Err2: The battery voltage is lower than the set termination voltage- Err3: The battery cannot bear the load discharge current or the line internal resistance is too large- Err4: Current is too large (current exceeds 3.1A)- Err5: Improper use or wiring error has caused the device to burn down and cannot be used (current sampling or control switch MOS burned)9. Note: If the battery is reversed, when the load is turned on and the load current is large (about> 0.8A), the circuit switch tube may be damaged!10. Secondary calibration operation: Press and hold three buttons to power on the tester at the same time, enter the calibration mode, first display the number of calibration records, then enter the formal calibration sampling program to display 0u0A, then short-circuit the input positive and negative poles and press "OK "Button to complete displaying J10u, apply a standard DC voltage of 10.00V between the input positive and negative electrodes, press the" OK "button, and then display J2.0A, apply to the output negative electrode (inflow direction) and input negative electrode (outflow direction) After a constant DC current of 2.0A, press the "OK" button once to complete the calibration. The tester will pre-check the calibration data. If the calibration data is reliable, it will display 4 calibration numbers in turn and then exit. If the pre-audit believes that the data is not reliable, discard the data and exit.

About The Product1. 6 port stereo speaker selector amplifier switch switcher 2. The speaker switcher allows the user to connect multiple pairs of speakers to a single stereo receiver or amplifier or vice versa to multiple amplifiers/receivers of a single speaker pair. 3. The device has a convenient button terminal that can accept up to 12 AWG speaker lines. 4. Note: this speaker switch does not allow multiple speaker pairs to be selected simultaneously. Only one pair of outputs can be selected at a time. 5. This speaker selection can also be used in the opposite way, imagine having multiple amplifiers connected to a speaker pair for setting. Because each stereo amplifier has its own sound characteristics, the user can connect different power amplifiers to the switch and then output to the same speaker pair. 6. Connect multiple speakers to an audio amplifier/receiver as loudspeakers to select a pair of speakers at a time. 7. Connect multiple amplifiers/receivers to a pair of speakers as an amplifier selection to select one amplifier/receiver. 8. The high-current amplifier protection circuit allows up to 6 pairs of speakers to be connected without damaging the amplifier. The protection circuit can safely protect unselected amplifiers or loudspeakers. 9. Select each time with a manual button on the front panel. Independent left/right channel grounding path, are compatible with all stereo amplifiers.Features1. Use convenient button terminal, can accept up to 12 AWG loudspeaker wires. 2. Supports up to 100 watts of amplifier power and 4 to 16 ohms of all types of speakers. 3. Sturdy, luxurious steel metal case and good shielding. 4. Independent left and right channel grounding path-in-type push-in terminal. 5. No external power supply is required. 6. Rated power: 100 watts per channel.
