Display Function: Speed Display, Battery Indicator, Fault Indicator, Total Mileage, Single Mileage2. Control Setting Functions: Power Switch Control, Wheel Diameter Setting, Idle Speed Automatic Sleep Time Setting, Backlight Brightness Setting, Startup Mode Setting, Drive Mode Setting, Voltage Level Setting, Controller Limit Value Setting.3. Communication Protocol: Uart Displays All the Contents of the Screen (full Display After Power on for 1s)3.1 Display of Battery Power and Remaining Power of Bms.3.2 Multifunction Display Area: Total Mileage Odo, Single Mileage Trip (unit: Mile, Km), Single Boot Time Time, Battery Voltage Vol, Dst: Battery Life3.3 Speed display AreaAvg: Average Speed, Max: Maximum Speed, Speed: Current Speed: Unit Mp/h Km/hThe Speed Signal is Taken from the Hall Signal in the Motor and Sent to the Meter by the Controller. (the Time of a Single Hall Cycle, Unit: 1ms) the Instrument Will Calculate the Real Speed According to the Wheel Diameter and Signal Data (the Number of Magnets Required by the Motor Hall)3.4 Vehicle Power Gear Adjustment, 0-9 Digital Display and Gear Bar Display;Instrument Environment Setting Instructions:P01: Backlight Brightness Level 1 is the Darkest and Level 3 is the Brightest;P02: Mileage Unit, 0: Km: 1: Mile;P03: Voltage Level: 24v 36v 48v 60v 64v (default 36v)P04: Sleep Time: 0, No Sleep. Other Numbers Are Sleep Time, Range: 1-60 (in Minutes).P05: Help Gear: 0, 3 Gear Mode, 1, 5 Gear Mode.P06: Wheel Diameter: Unit. Inches; Accuracy: 0.1; This Parameter is Related to the Display Speed of the Instrument, and Needs to Be Entered Correctly.P07: Speedometer Magnet No.: Range: 1-100.This Parameter is Related to the Speed Displayed by the Instrument and Needs to Be Input Correctly; if It is an Ordinary Hub Motor, Directly Input the Magnetic Steel; if It is a High-speed Motor, It is Also Necessary to Calculate the Reduction Ratio, Input Data = Number of Magnetic Steel x Reduction Ratio.For Example: the Number of Motor Magnets is 20, the Reduction Ratio is 4.3: the Input Data Is: 86 = 20 x 4.3P08: Speed limit: Range 0-100km/h, 100 Means Unlimited Speed.The Data Entered Here Represents the Maximum Running Speed of the Vehicle: for Example, Input 25, Which Means That the Maximum Running Speed of the Vehicle Will Not Exceed 25km/h; the Running Speed Remains the Set Value, the Error: 1km/h; (power and Steering Speed Limit).Note: the Values there Are in Kilometers. when the Unit Setting is Converted from Kilometers to Miles, the Speed Value on the Display Interface is Automatically Converted to the Correct Mile Value, but the Speed Limit Value Set in This Menu Under the Mile Interface is Not Converted. the Mile Speed Does Not Match the Actual Speed Limit.Note: P09-P15 Menu is Only Valid in Communication State.P09: Zero Start Non-zero Start Setting, 0: Zero Start. 1. a Non-zero Start.P10: The Drive Mode is Set to 0: Power Drive (how Much Power is Output is Determined by the Power Gear, the Switch is Invalid).1: Electric Drive (driven by Turning the Handle, when the Power Gear is Invalid).2.
