3. Inspect the battery for cracked or broken case or cover. If
battery is damaged, do not use tester.
4. If the battery is not sealed maintenance free, add distilled
water in each cell until battery acid reaches level
specified by the manufacturer. This helps purge
excessive gas from cells. Do not overfill.
5. If necessary to remove battery from vehicle to test,
always remove ground terminal from battery first. Make
sure all accessories in the vehicle are off to ensure you
do not cause any arcing.

OPERATION & USE ：
Note: Each time you connect the tester to a battery, the
tester will run a quick cable verification to ensure a proper
connection through the output cables to sensors in the clamp
jaws. If the connection checks out OK, the display will
momentarily flash "CHECK COMPLETE" and proceed to the
Home Screen. If the connection is poor, the display will show
"CABLE ERROR" – "REPLACE CABLE". In this case, check
cable connections for visible signs of damage, as you may
need to replace the cable ends.
BATTERY 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 6 pcs 1.5V batteries into the
battery chamber. Oxyride
recommended because of the initial 1.7 Volt output. If
the 1.5V battery runs out of power, screen will show
"POWER LOW". Replace those 6 pcs 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.
