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.
Operation & Use
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 a 9V battery into the battery chamber of the 390PT. If the 9V
battery runs out of power, screen will show “INTERNAL BATTERY LOW”. Replace with
proper 9V battery before starting the test.
Note that nothing will be seen on the display until tester is connected to a vehicle battery.
3. Make sure the battery terminals are clean. Wire brush them if necessary. Clamp the
black lead to the vehicle negative battery terminal. Clamp the red lead to the vehicle
positive battery terminal. Clamp onto the lead part of the terminal. Clamping onto the
iron or steel part of the terminal can lead to erroneous results.
