  3>.Suitable for lithium ion batteries, polymer batteries;
  4>.Suitable for all electric two-wheel or three-wheel batteries in the voltage range.

5.Instruction for use:
  1>.Hold down the setting key for 3 seconds, P01 flashes;
  2>.Press the Set key once, The V1 voltage flashes, Press the Up or Down key to select required parameters;
  3>.Press the Up or Down key once, The V2 voltage flashes;
  4>.After setting parameters V1 and V2, hold down the Settings key for 3 seconds to save the Settings and exit.

6.Description of Working Mode:
  1>.P01 charging mode: when the detection voltage is lower than V1 voltage, K.K contact is connected; when the detection voltage is higher than V2 voltage, K.K contact is disconnected;

  2>.P02 discharge mode: When the detection voltage is higher than V2 voltage, K.K contact is connected; when the detection voltage is lower than V1 voltage, K.K contact is disconnected;

  3>.P03 Switching mode within interval: when the detection voltage is between V1 and V2, K.K contact is switched on and other contacts are disconnected;

  4>.P04 Switch on mode outside interval: when the detection voltage is between V1 and V2, the K.K contact is disconnected and the others are switched on;

  5>.P05 fixed-point monitoring mode: when the detection voltage is higher than V1, K.K contact is connected, and when it is lower than V1, K.K contact is disconnected;

  6>.P06 fixed-point self-locking monitoring mode: when the detected voltage is higher than V1 voltage, K.K contact will always be switched on until the artificial power failure;

  7>.P07 fixed-point movement monitoring mode: When the detection voltage is equal to V1 voltage (±0.1V) each time, K.K touch is switched on;

  8>.P08 voltage error correction, range of ±5V adjustable;
  9>.P09 delay function: 1-200 minutes adjustable;

7.Note About Setting Method:
  1>.After V1 and V2 parameters are set in P01, the parameters used in other modes are P01 parameters. When setting, PO1 displays flashing, press the up or down key to select P01-P09 mode. Save and exit the setting mode must be operated in the working mode, and other modes do not support exit;
  2>.In the normal display, long press up the key for 2 seconds, can close the digital tube display 2;
  3>.In normal display, press down button to view the current working mode, lower limit voltage, upper limit voltage, error correction voltage.
