A poor connection will prevent testing and the battery tester will display the message CHECK CONNECTION. If this message appears after you have correctly reconnected the clamps, clean the terminals and reconnect.
It is recommended that batteries are always tested using both battery posts. However, if used in 'jump start post' mode, the Midtronics EXP-1050 battery tester will compensate for the extra resistance of the additional cable.
1. Select BATTERY TEST or START-STOP BATTERY TEST.
2. Select the BATTERY LOCATION
3. Select the negative POST TYPE (IN-VEHICLE ONLY)
