1.Description:
   VAH9810S is a multi-function meter, which can display various physical parameters such as voltage, real-time current, peak current, real-time power, peak power, capacity, usage time, etc. in real time, and the way of collecting current is to collect current through non-contact Hall sensor , safe, stable and convenient for wiring, and can realize over-power, over-voltage, under-voltage and over-current protection through the reserved relay interface.

  Moreover, the instrument uses a 2.4-inch color LCD as a display, which displays more comprehensive, clear and easy-to-observe data. This meter is ideal for applications that require monitoring of output voltage and current, as well as charging and discharging batteries.

2.Feature:
  1>.Bidirectional current detection, users who detect charging and discharging can easily detect bidirectional current without changing the wiring direction;
  2>.High-performance DC Hall sensor is used to collect current, which is safe, convenient and accurate;

  3>.Power-off memory function, after power-off, the ampere-hour (AH) before power-off can be memorized, which is convenient for observation and measurement;
  4>.The ampere-hour (AH) number can be filled or cleared with one key, which does not affect the direct charge and discharge measurement;

  5>.The voltage, current, ampere hour, time and power are displayed at the same time, and the displayed information is comprehensive and clear;
  6>.With an output shutdown function key, the output can be turned on or off flexibly;

  7>.With overvoltage, overcurrent, overpower, undervoltage protection;
  8>.It can be calibrated online, which is convenient for customers to correct errors in time;

  9>.The LCD screen can be automatically turned off and on to reduce the power consumption of the product;
  10>.The relay port can be switched to the buzzer port to realize the sound alarm function;
  11>.The undervoltage capacity can be automatically cleared, and the overvoltage capacity can be automatically filled up to facilitate long-term use by customers, and automatically correct errors.

4.Instructions for use:

  1>.Key operation instructions:
     1.1>.Long press "UP" for more than 5 seconds,the capacity will be automatically filled up;
     1.2>.Long press "DOWN" for more than 5 seconds, the capacity will automatically return to zero;
     1.3>.Short press "UP" screen brightness increases;
     1.4>.Short press "DOWN" screen brightness decreases;
     1.5>.Long press "OK" key for more than 5 seconds to enter the parameter setting function, short press "DOWN" or "UP" to switch the setting parameters, short press the "OK" to select the adjustment parameter, short press "DOWN" to switch the step value of the adjustment parameter, and short press the "UP" to change the parameter value, long press the "OK" for more than 5 seconds to exit the parameter setting function and save the data;

  2>.Function Introduction:
     2.1>."CLR" current clearing function, when the no-load current is not zero, enter this option, click the up button to clear the no-load current;
     2.2>. "BAT" sets the total capacity of the battery, which corresponds to the nominal AH number of the battery;

     2.3>."BPC" sets the percentage of remaining capacity;
     2.4>."LED" sets the backlight brightness of the LCD display, 0-10 is set according to your needs. The higher the level, the higher the brightness;

     2.5>."STE" sets the time value of the LCD screen, and the LCD screen turns off when the running time is greater than the set value;
     2.6>."STI" sets the current value of the LCD screen. When the measured current is less than the set value and the time is greater than STE, the LCD screen will automatically turn off, and it will automatically light up when it is greater than STI;

     2.7>."BKC" sets the color of the LCD interface to choose from black and white and color;
     2.8>."LAG" sets the display language type (Chinese or English);

     2.9>."LBR" "LBR" backlight breathing light alarm effect switch, after turning on the screen, the remaining power is less than 20% or the voltage is lower than LVP, the alarm will flash, and the breathing display will also be displayed when the charging current is greater than STI;
     2.10>."ADS" communication address code;

     2.11>.The "PAI" current is reset to 0; after the no-load current is cleared, the temperature drift of the transformer makes the current value not 0. Use this item to set to prevent temperature drift. After the no-load current is cleared, the actual current value is not 0 due to other reasons. By setting this parameter, the current value is cleared to zero;
     2.12>."OVP" charging overvoltage protection value, the voltage is greater than the set value during the charging process, the charging relay can be automatically disconnected, and the capacity is automatically filled;

     2.13>."LVP" discharge undervoltage protection value; during the discharge process, the voltage is lower than the set value, the discharge relay can be automatically disconnected, and the capacity is automatically cleared;
     2.14>."NCP" charging overcurrent protection value;

     2.15>."OCP" discharge overcurrent protection value;
     2.16>."OPP" over-power protection value;

     2.17>."RTO" default protection on-off function when booting;
     2.18>."DEL" relay delay action time;
     2.19>."MOD" relay working mode; three relay working modes, choose according to your needs.
