WARNING:
Pursuant to California Proposition 65, this product contains chemicals
known to the State of California to cause cancer and birth defects or
other reproductive harm. Wash hands after handling.
1. Working in the vicinity of a lead acid battery is dangerous. Batteries
generate explosive gases during normal battery operation. For this
reason, it is of utmost importance, if you have any doubt, that each
time before using your tester, please read these instructions very
carefully.
2. To reduce risk of battery explosion, follow these instructions and
those published by the battery manufacturer and manufacturer of
any equipment you intend to use in the vicinity of the battery.
Observe cautionary markings on these items.
3. Do not expose the tester to rain or snow.
PERSONAL SAFETY PRECAUTIONS:
1. Someone should be within range of your voice or close enough to
come to your aid when you work near a lead acid battery.
2. Have plenty of fresh water and soap nearby in case battery acid
contacts skin, clothing or eyes.
3. Wear safety glasses and protective clothing.
4. If battery acid contacts skin or clothing, wash immediately with soap
and water. If acid enters eye, immediately flood eye with running cold
water for at least ten minutes and get medical attention immediately.
5. NEVER smoke or allow a spark or flame in vicinity of battery or engine.
6. Be extra cautious to reduce risk of dropping a metal tool onto the
battery. It could spark or short-circuit the battery or other electrical
parts and could cause an explosion.
7. Remove personal metal items such as rings, bracelets, necklaces and
watches when working with a lead acid battery. It can produce a short
circuit current high enough to weld a ring or the like to metal causing
a severe burn.

PREPARING TO TEST
1. Be sure area around battery is well ventilated while battery is being
tested.
2. Clean battery terminals. Be careful to keep corrosion from coming in
contact with eyes.
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.
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 6pcs 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.
BEFORE TEST

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.

NOTE: Under certain conditions the follow messages may be displayed.
The alternator is not providing sufficient current to
the battery. Check the belts to ensure the alternator
is rotating with engine running. If the belts are
slipping or broken, replace the belts and retest.
Check the connections from the alternator to the battery. If the
connection is loose or heavily corroded, clean or replace the cable and
retest. If the belts and connections are in good condition, replace the
alternator.
The system is showing normal output from the
alternator, no problem is detected.
The voltage output from the alternator to the battery
exceeds the normal limits of a functioning regulator.
Check to ensure there is no loose connection and the
ground connection is normal. If there is no connection issue, replace the
regulator. Since most alternators have the regulator built-in, this will
require you to replace the alternator. The normal high limit of a typical
