Feature:1. MULTIPLE FUNCTIONS AND PROTECTION: The coulommeter can measure voltage, current, power, charge and discharge capacity, watt hour, time and other physical parameters. You can also set parameters to implement multiple protection functions, such as overvoltage protection, undervoltage protection, overcurrent protection, overpower protection, and overtemperature protection2. EXCELLENT ACCESSORIES AND EXQUISITE APPEARANCE: Battery monitor shortcut keys made of silicone material, which not only greatly simplifies operation steps, but also feels comfortable. Acrylic panel design can effectively protect the screen, easy to clean, dustproof and better light; The shunt and screws are made of brass material with good conductivity, low calorific value and low power consumption, does not consume too much battery power in standby mode; After the new interface is optimized and upgraded, the font is larger and the layout is more reasonable, which is clear at a glance3. BUILT IN BUZZER: When a certain value of battery monitor exceeds the preset protection limit value, will start the protection function of the instrument, and the alarm sound will sound and popup window will remind or disconnect the circuit through the relay to protect the instrument from damage (relay needs to be equipped separately)4. REAL TIME MONITORING: Automatically recognize and monitor current in charge or discharge directions, Voltmeter can automatically recognize current direction and monitor battery capacity in real time5. VARIOUS CONTROL MODES: Voltage tester supports display control, can provide protocol, using 485, the secondary development can be carried out on the development tools such as serial assistant. Can switch addresses. Can switch addresses, respectively control 99; Supports mobile APP control. After downloading and installing the APP, you can view all relevant data and curves on the APP through the built in Bluetooth connection, and set all functions through the mobile APP6. APPLICABLE SCENARIO: Voltage Tester has 2.4in color display, display current function menu, parameter setting and measurement data, display information is comprehensive and user friendly, charging and discharging at a glance, make your journey without worry. Whether acid batteries, ternary lithium batteries or lithium iron phosphate, or other types of batteries, as long as the battery voltage is within the measured range, all will workSpecification:Item Type: Smart Battery MonitorModel: KH140FMaterial: Acrylic, brass, siliconeScreen: 2.4in color LED screenSampling Mode: ShuntVoltage Measurement Range (external power supply): 0-120VVoltage Measurement Range (self powered): 10-120VVoltage Resolution: 0.01VCurrent Measurement Range: 0~400ACurrent Resolution: 0.01ARelay: No relay provided, needs to be configured by yourselfTemperature Measurement Range: -20-120Capacity Display Range: 0% to 100 percentPower Measurement Range: 0~72KWPower Resolution: 0.01WAmpere Measuring Range: 0~9999.99AhCapacity Resolution: 0.001AhWatt hour Measurement Range: 0~9999.99kWhWatt hour Resolution: 0.001WhTime Measurement Range: 0~999: 59: 59STime Resolution: 1 SecondBluetooth Distance: Barrier Free Distance: Up to approx. 10meter / 32.8ftVoltage Accuracy: 1%+2 wordsCurrent Accuracy: 1%+5 wordsSampling Rate: 1 time per secondMeasuring Board Power Consumption: About 0.4WDisplay Head Power Consumption: About 0.5WOver Power Protection: 0-99999.99WDischarge Overcurrent Protection: 100ACharge Overcurrent Protection: 100AUndervoltage Protection: 0 to 120VExternal Overtemperature Protection: -20-120Protection And Recovery Time: 0-99sStandby Time: 0-60sDelay Time Setting: 0-99sMailing Address: P01-P99 99 in total.Package List:1 x Display Module1 x Measurement Module1 x Sampler1 x Temperature Sensor1 x 5meter Line1 x 3P Row Line1 x 4P Row Line1 x 3P Wiring Terminal1 x User Manual
