The multimeter may be affected by the surrounding magnetic field before the test, so the numbers will jump on the screen when the test leads are not connected. This phenomenon does not affect the use of multimeter.

Please remove the two screws in the black portion behind the kick stand and take it off, and check if the battery and the two fuses are in good condition. Please contact our support team directly for help if them are in good condition: support@astroai.com

Please note that test leads have rubber protective covers, and the covers can be removed. You can pull them off if needed.
