What to do if my Schumacher Electric BT-175 Test Equipment screen flickers or shows - - - -?

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.
