Description VAC8610F 500V 300A Wireless DC Voltmeter Ammeter Temperature Capacity Coulometer 2.4" Color Screen Electronic Documentation: https://pan.baidu.com/s/1C4S8di3BOjNl-9tAvVeN5g Password: 7fp8 Operation Video: https://v.youku.com/v_show/id_XNTExMDM3MTI0NA==.html Product Description: VAC8610F is a multifunctional instrument based on 2.4G wireless data transmission technology, which can display voltage, current, power, capacity, energy, temperature, running time and other physical parameters in real time. Battery charging and discharge management, overvoltage, under-voltage, overcurrent protections and buzzer alarm can be realized by two relay interfaces reserved. And the instrument uses 2.4-inch color liquid crystal as the display, the display data is more comprehensive, clear, easy to observe, reserved communication interface, easy to secondary development. Features: 1. Wirelessly transmit data to avoid the interference caused by complicated wiring between the display and the detection module, and the wiring is easier; 2. The Hall sensor is used to realize non-contact detection of current without disconnecting the wire, which is safe, reliable and convenient; 3. Voltage, current, power, temperature (optional), capacity, percentage of remaining capacity, and running time are displayed at the same time; 4. Dual-relay interface for charging and discharging, 5 relay working modes can realize automatic disconnection and automatic closing of charging and discharging; 5. With charge overvoltage, discharge under-voltage, charge overcurrent, discharge overcurrent protections, and with buzzer alarm prompt function; 6. With power-off memory function, it can record the number of AH and WH before power-off; 7. When charging, the percentage progress bar is switched to the color running light display to enhance the display effect; 8. With voltage, current and temperature waveform curve display function; 9. With TTL serial port communication function by default, it is convenient for secondary development; 10.Chinese and English language selection, two display colors can be switched, three display interfaces can be adjusted, suitable for different customer needs. Communications Description: 1. The USB of display board and the USB of the measurement board of this instrument are equipped with TTL serial communications by default, and our USB communications board can be used for data reading. When the communications board is used to communicate with the measurement board, the communications board dial switch 1 and 3 are in the ON state, and 2 and 4 are in the OFF state. When using the communications board to communicate with the display board, set the DIP switch 2 and 4 of the communications board to the ON state, and 1 and 3 to the OFF state; 2. It comes without 485 communications by default. If the 485 communications to the measurement board is needed, please contact us to pay extra money.

Thank you for your understanding! Function Introduction: The instrument has a total of 27 parameter settings, which greatly enhances the general applicability of this product and meets the needs of customers in various scenarios for battery testing. Refer to the manual for specific parameter descriptions and setting methods. LCK: Key lock control item BAT: set the total capacity of battery CON: charging relay control option OUT: Discharge relay control option BPC: Set the percentage of remaining battery capacity CER: No-load current clear option STR: Timing function control option TTL: Power-on default discharge output relay status setting option NCP: Set charging overcurrent protection option OCP: Set discharge overcurrent protection option SFH: Communication channel search function FCH: Communication channel setting function OVP: set charging overvoltage protection option LVP: Set discharge undervoltage protection option STV: Set the discharge start voltage value option BWH: set the total energy value of the battery DEL: Set the delay action time value of the relay STI: Set the current value option of the screen TME: Set the time value option for rest screen HUM: LCD display color matching switch option LAG: Set the LCD display language options OTP: Set the discharge time value option RUN: Start and stop control options for waveform refresh in curve mode UYD: curve display voltage magnification options IYD: Curve display current magnification options RSH: Curve refresh time adjustment option MOD: Relay working mode switching option Description of Battery Progress Bar Change: When the meter detects that a battery is charging, the percentage progress bar will display the status of the colorful water lamp, and there is a "+" sign before the current value; the progress bar will automatically switch to a green bar when discharging, and a "-" sign will be displayed before the current value. Analysis of Relay On/Off Mode: There are 5 kinds of relay working modes of the instrument. Users can set the working mode of the relay according to actual needs when using the relay. 1: Actual measured voltage value 2: Actual measured current value 3: Actual measured power value 4: Actual accumulated AH number 5: Actual accumulated WH number 6: Key lock indicator 7: Wireless signal indication 8: Actual measured temperature value 9: charging relay on/off status display A: On/off status display of electric discharge fan B: OTP=0 ordinary timer; OTP>O timing timer from left to right: hours: minutes: seconds C: When the current is greater than 0, the time required to fully charge is displayed; when the current is less than 0, the remaining battery time is displayed D: Function option display area E: Battery capacity progress bar, it displays the state of colorful running light when charging, and the state of green progress bar when discharging F: percentage of remaining capacity Payment Terms 1.We accept PayPal only. 2.All major credit cards are accepted through secure payment processor PayPal. 3.Payment must be received within 7 business days of auction closing. 4.We ship to your eBay or Paypal address.
