Description The KL-F series volt-ampere meter is a new type of coulomb meter that can measure various physical parameters such as voltage, current, power, charge and discharge capacity, watt-hours, and time. At the same time, it can also set parameters to achieve over-voltage protection, under-voltage protection, Multiple protection functions such as over current protection, over power protection, and over temperature protection. The meter can automatically identify the direction of the current, and can monitor the battery capacity in real time, can view the measured data through Bluetooth, and can control the meter and firmware upgrade through the mobile phone APP. The product automatically recognizes and detects the current in both charging and discharging directions. When charging, the color of the current is green when discharging, the color of the current is blue. Suitable for a variety of batteries:ternary lithium batteries, lead-acid batteries, lithium phosphate batteries, etc., as long as the battery is within the voltage measuring range. The shunt and screws are made of pure copper material, which has good electrical conductivity, low heat generation, and low power consumption. In the standby state, it will not consume too much battery power. Support Bluetooth connection mobile phone APP control, after downloading and installing the APP, through the built-in Bluetooth connection, and all functions can be set through the mobile phone APP. The product can be set with over-voltage, under-voltage, over-current, over-power, and external over-temperature protection. When the value is out of the protection value range, the output state of the instrument is turned off (need to be used with a relay) to prevent damage to the electrical equipment. The protection recovery time and delay time can be set, which is suitable for various occasions. The product has added a self-calibration function, and the current and capacity values can still remain accurate after long-time work. Amp-hour, watt-hour, and time data can be cleared during the measurement proce without affecting the next measurement. The voltage and current values can also be fine-tuned to ensure accurate capacity. The product can be upgraded through the online firmware of the mobile phone, which increases the guarantee for the operation of the product. The product can accurately measure parameters such as voltage, current, battery capacity, power, power consumption, ambient temperature, battery life, charging time, and battery cumulative capacity.
