      Emma SmithJul 27, 2025
      If the screen flickers or shows - - - - on your Schumacher Electric Test Equipment, it indicates that the voltage of the battery being tested is unstable. If the battery was recently charged, wait 15-30 minutes to allow the voltage to stabilize before retesting. If any accessories are on, turn them off, recharge, and then retest the battery. If the reading remains the same, consider replacing the battery.

      If the display screen on your Schumacher Electric Test Equipment is blank, it could be because the voltage of the tested battery is too low for the tester to read, or the clamps are not connected properly. Recharge and retest the battery. If the reading remains the same, replace the battery. Also, check the battery clamps to ensure they are properly connected.
