INSTRUCTIONS
Current Measurement: 
  1. Turn off the vehicle power and connect the tester.
  2. Press the "POWER" button to switch on the power.
  3. Press "MODE" button to change the function to current measurement mode. The letter "A" shall display on the LCD.
  4. Remove the fuse from the fuse box in the vehicle. Put the fuse into the fuse probe.
  5. Plug the fuse probe into the fuse socket. User can start the measurement. User can turn on the vehicle if it is necessary.
  6. Current can only be measured through the fuse probe.
Voltage Measurement:
  1. Turn off the vehicle power and connect the tester.
  2. Press the "POWER" button to switch on the power.
  3. Press "MODE" button to change the function to voltage measurement mode. The letter "V" shall display on the LCD. User can start the measurement.
  4. During the measurement, if the voltage is less than 1 volt, no voltage will be displayed.
  5. During the measurement, if the measured polarity is reversed, "ERR" will be displayed, and buzzer will buzz. Please reverse the test probe and do the measurement again.
Continuity Measurement:
  1. Same step as voltage measurement 1 – 3.
  2. If the resistance is less than 1k ohm, "ERR" will be displayed, and buzzer will buzz. This indicates that it's a continue circuit.
