KH-F series User Manual: http://68.168.132.244/KH/Manual_en_zx.pdf Android phone App link: http://68.168.132.244/KH/KH-F.html                                                                                   (Copy Link to Mobile Browser Download) IOS mobile App link: Search Apple Store for "KH-F" Quick Installation Video： https://www.youtube.com/watch?v=ptU_pHVGS8A Relay wiring method： https://www.youtube.com/watch?v=N5OOXGh4NLQ&t ► Measuring voltage 0-120V, measuring current 0-100A/400A/600A, measuring capacity 0~9999.99AH; ► Applicable to various batteries, such as ternary lithium batteries, lead-acid batteries, lithium iron phosphate batteries, etc.; ► 2.4-inch high-definition color display, silicone buttons； ► The sampler is equipped with a shell, which is easy to install and provides insulation protection; ► The shunt is made of pure copper material, which has good conductivity and will not consume too much battery power in standby mode; ► It can automatically identifycharging and discharging, the charging capacity increases, the discharging capacity decreases, remaining capacity is displayed in real time; ► It supports setting two different screen brightnesses during the day and night, and can freely switch between three off-screen modes. ► Overvoltage, undervoltage, overcurrent, overpower, external overheating, low temperature protection can be set. When the protection condition is reached, there will be an alarm sound and a pop-up window reminder, and the relay will disconnect the circuit (the delivery list does not include the relay); ► Provide mobile APP, support Android and Apple mobile phones to view data through Bluetooth, view charge and discharge curves, and support historical data export; ► Provide communication protocol, use 485 communication to control the instrument; ► Brand new settings interface, designed with reason and intelligence, making it more convenient to operate. ► The display module has a built-in buzzer. When a certain parameter value              exceeds the preset protection limit, the instrument will activate the protection function: 1. An alarm sound will sound and be accompanied by a pop-up reminder; 2. The circuit will be disconnected through a relay to protect the instrument from damage (relay needs to be separately purchased). The newly designed sampler case is not only convenient for fixing the sampler, but also provides good insulation protection. >The instrument can be set to over-voltage, under-voltage, over-current, over-power, and over-temperature protection. When the values are not within the protection range, the instrument output state is turned off, and the relay disconnects the circuit (relay is required). This is to prevent damage to the electrical equipment. >The protection recovery time and delay protection time can be set, making it suitable for various occasions. No matter if it is a lead-acid battery, ternary lithium battery, lithium iron phosphate battery, or any other type of battery, as long as the battery voltage is within the measuring range, all are applicable. Automatically recognize and monitor the current in both directions of charging and discharging.
