Parameter:
Working voltage: DC 5V/12V/24V optional
Size: length 5.6 x 4.3 x 1.7mm(length*width*height)
Weight: 24 grams
Detection range: DC0-99.9V minimum 0.1V start-up
NOTE: (some customers report that the detection is not stable) as a result, it is found that the customer has detected the AC voltage, not used to detect the AC voltage, which may cause instability or even burn the board, and the pulsating DC is also prone to fluctuate (DC electrical signal directly rectified without filtering). It is necessary to detect the pure DC signal, remember! Otherwise, the consequences shall be borne by yourself.
Function introduce:
Power on indicates that the measured voltage is in standby mode
First, set two basic parameters, the lower limit voltage V1 and the upper limit voltage V2
1: Press the setting key once to display "F-1" flashing
2: Press the setting key for the second time to display the default V1 value "XX. X" flashing press the "plus" key or "minus" key to adjust the lower limit parameter v1
3: Press the setting key for the third time to display the default V2 value "XX. X" flashing press the "plus" key or "minus" key to adjust the upper limit parameter V2 (at this time, if the V1 parameter is greater than V2, the "err" error prompt will be displayed, and the parameter needs to be changed, and it is normal to keep V1 less than V2)
4: Press the setting key for the fourth time, and the parameter will be saved permanently to exit
5: In standby mode, press the "minus" button for 3 seconds to turn off the display, and then press the button for 3 seconds to turn on the display. Designed to reduce power consumption.
Function description:
1: F-1 charging monitoring: when the measured voltage is lower than the voltage V1, the pull-in voltage of the relay is higher than V2, and the relay is disconnected.
2: F-2: discharge monitoring: when the measured voltage is higher than the voltage V2, the relay is closed and the voltage is lower than 1, the relay is disconnected.
3: F-3: Section external pull in: when the measured voltage is between V1 and V2, the relay is disconnected. Relay engagement in other states.
4: F-4: in section pull in: when the measured voltage is introduced between V1 and V2, the relay pulls in then other state relays are disconnected.
5: F-5: fixed point monitoring: when the measured voltage is higher than V1, the relay is closed, and lower than V1, the relay is disconnected.
6: F-6: fixed point self-locking monitoring: when the measured voltage is higher than V1, the relay is always closed until the power is cut off manually.
7: F-7: fixed point pulse monitoring: when the measured voltage is equal to V1 (floating up and down 0.1V) each time, the relay outputs the inching signal.
