CPX-900 EU
1: Introduction
Personal Precautions
Risk of explosive gases.
Never smoke or allow a spark
or ame in the vicinity of a
battery.
Batteries can produce a highly
explosive mix of hydrogen gas
and oxygen, even when the bat-
tery is not in operation. Always
work in a well-ventilated area.
Wash hands after handling.
REQUIRED BY CALIFORNIA PROP. 65:
Battery posts, terminals, and related acces-
sories contain lead and lead compounds,
chemicals known to the state of California
to cause cancer and birth defects or other
reproductive harm.
Inspect the battery for damage and check the electrolyte level. If the electrolyte level is too
low, replenish it and fully charge the battery. Always use the necessary safety precautions when
working with batteries to prevent severe injury or death. Follow all manufacturers’ instructions
and BCI (Battery Council International) safety recommendations, which include the following
precautions:
9Battery acid is highly corrosive. If acid enters your eyes, immediately ush them thoroughly
with cold running water for at least 15 minutes and seek medical attention. If battery acid
gets on your skin or clothing, wash immediately with a mixture of water and baking soda.
9Always wear proper safety glasses or face shield when working with or around batteries.
9Keep hair, hands, and clothing as well as the analyzer cords and cables away from moving
engine parts.
9Remove any jewelry or watches before you start servicing the battery.
9Use caution when working with metallic tools to prevent sparks or short circuits.
9Never lean over a battery when testing, charging, or jump starting.
Symbols Conventions Description
Symbol Description
!
The safety symbol indicates instructions for
avoiding hazardous conditions and personal injury.
The safety symbol with the words CAUTION,
WARNING, or DANGER indicates instructions for
avoiding hazardous conditions and personal injury.
The wrench symbol indicates procedural notes and

The analyzer uses function-specic
applications accessed through a
series of menus and icons to guide
users through the battery testing
process for consistent testing
implementation and accuracy.
These are accessed using the
tester’s touch screen display. Test
results can be displayed on the full-

Inspecting the Battery
Before starting the test visually inspect the battery for:
•Cracked, buckled, or leaking case. If you see any of these defects, replace the battery.
•Corroded, loose, or damaged cables and connections. Repair or replace them as needed.
•Corrosion on the battery terminals, and dirt or acid on the case top. Clean the case and termi-
nals using a wire brush and a mixture of water and baking soda.
•Low electrolyte level. If the electrolyte level is too low, add distilled water to ll up to ½ above
the top of the plates and fully charge the battery. Do not overll.
•Corroded or loose battery tray and hold-down xture. Tighten or replace as needed.
Testing Out-of-Vehicle (Battery Test)
The preferred battery test location is in the vehicle. However, if you plan to test out of the vehicle:
•Always disconnect the negative cable from the battery rst and reconnect it last.
•Always use a carry tool or strap to lift and transport the battery.
Failure to properly install lead terminal
adapters, or using adapters that are dirty or
worn, may cause false test results.
When testing side-post or Group 31 batteries, always use lead terminal adapters
provided with the tester—do not test at the battery’s steel bolts. To avoid damage,
never use a wrench to tighten the adapters more than ¼turn.
Testing In-Vehicle (System Test)
Before starting the test, inspect the alternator drive belt. A belt that is glazed or worn, or lacks the
proper tension, will prevent the engine from achieVIDg the rpm levels needed for the test.
The preferred test position is at the battery posts. If you must test at a remote-post location, it
should have both a positive and negative post. Otherwise, you must remove the battery and
perform a System Test.
At the start of the test, place the vehicle transmission in PARK, make sure all vehicle accessory loads
are o, the key is not in the ignition, and the doors are closed.
Connecting To The Battery
Connect the red clamp to the positive (+) terminal and the black clamp to the negative (–) terminal.
If you connect the clamps in the wrong polarity (red to negative or black to positive), the analyzer
displays "CLAMPS REVERSED!" Reconnect the clamps.
To make sure both sides of the clamps are gripping the terminals, rock the each clamp back and
forth. A poor connection will prevent testing, and the analyzer displays the message CHECK
CONNECTION. If the message reappears after you have correctly reconnected the clamps, clean the
terminals and reconnect.
