 Specific parameters: Detection voltage range: 0~50V, the minimum 0.01V is adjustable. 1: It can detect DC voltage between 0~50V, and the relay output can control the line on and off within 5A. 2: Add the ms level delay time to prevent the output from oscillating and causing damage to the entire circuit. 3: Measurement accuracy of 0.04V, can display off for a long time, reduce power consumption 4: Input voltage: DC 12 V 5: Synchronous acquisition of data serial output 6: Function description: P--1: Charging monitoring: When the measurement is lower than the voltage V1, the relay is closed, and the voltage is higher than V2. The relay is disconnected; P--2: Discharge monitoring: When the measurement is higher than the voltage V2, the relay is closed, and the voltage is lower than V1. The relay is disconnected; P--3: Out-of-range pull-in: When the measured voltage is between V1 and V2, the relay is disconnected, and the relay is closed in other cases; P--4: Interval in the interval: When the measured voltage is between V1 and V2, the relay is closed, and the relay is disconnected in other cases; P--5: Fixed point monitoring: When the measurement is higher than the voltage V1, the relay is closed, and the voltage is lower than V1. The relay is disconnected; P--6: Fixed-point self-locking monitoring: when the measured voltage is higher than V1, the relay pulls in; always keeps the pull-in; until the manual power-off P--7: Fixed-point pulse monitoring: When the measured voltage is equal to V1 (up and down can be floated 0.02V), the relay outputs a jog signal. 7: Setting instructions: Power on to display the measured voltage into standby mode; Press K1 for the first time (more than 1 second is required to prevent false triggering)             The screen flashes: P -1: K2 plus mode, K3 minus mode Pressing the second K1, the screen flashes: 12.50 means: V1=12.5V: K2 and K3 adjust V1 Pressing the third K1, the screen flashes: 13.50 means: V2=13.5V: K2 and K3 adjust V2 Pressing the fourth K1, the display shows that the measured voltage indicates to enter the standby state; Press K4 in standby mode to permanently turn off/on the display and switch the low power mode.
