BEFORE TEST
1. Before you test a battery in a vehicle, turn off the ignition, all
accessories and loads. Close all the vehicle doors and the
trunk lid.
2. Make sure you have put 4pcs 1.5V batteries into the battery
chamber. Oxyride batteries are not recommended because
of the initial 1.7 Volt output. If the 1.5V battery runs out of
power, screen will show "REPLACE INTERNAL BATTERY"
or" POWER LOW". Replace those 4pcs 1.5V batteries
before starting the test.
Note that nothing will be seen on the display until the tester
is connected to a vehicle battery.
3. Make sure the battery terminals are clean. Wire brush them
if necessary. Clamp the black load lead to the vehicle
negative battery terminal. Clamp the red load lead to the
vehicle positive battery terminal. Please clamp on the lead
part of the terminal only. Clamping on the iron part of the
terminal will lead to wrong test results.
