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 6pcs 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

only. Clamping on the iron part of the terminal will lead to wrong
test results.
