Preparing to Test, Connecting the Tester

2.9WARNING: 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, you read these instructions very carefully.

2.10To 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.

2.11Do not expose the tester to rain or snow.

3.PREPARING TO TEST

1.Be sure the area around the battery is well ventilated while the battery is being tested.

2.Clean the battery terminals. Be careful to keep corrosion from coming in contact with your eyes.

3.Inspect the battery for a cracked or broken case or cover. If the battery is damaged, do not use the tester.

4.If the battery is not a sealed maintenance free battery, check the level of each cell and if necessary, add distilled water until the battery acid reaches the level specified by the manufacturer. This helps purge excessive gas from the cells. Do not overfill.

5.If it is necessary to remove the battery from the vehicle to test it, always remove the ground terminal from the battery first. Make sure all accessories in the vehicle are off to ensure you do not cause any arcing.

4.OPERATING INSTRUCTIONS PAPER LOADING

1.Hook the tester up to a vehicle battery.

2.Open the clear cover on the top of the tester.

3.Place the roll of paper in the cover with the paper lead on the bottom.

4.Insert the paper into the paper slot until it automatically starts feeding.

5.Make sure the paper comes through the slot in the clear cover before closing it.

NOTE: This is a thermal printer. If the printer does not print, remove the paper roll, turn it over and re-insert it.

NOTE: If you have a paper jam, pull the paper out slowly and carefully from the roll side of the tester and re-insert it properly.

CONNECTING THE TESTER

1.Before you test a battery in a vehicle, turn off the ignition, all accessories and loads. Close all of the vehicle’s doors and trunk lid.

2.Make sure you have put the six 1.5V AA batteries into the battery compartment. If the 1.5V AA batteries run out of power, the screen will show POWER LOW. Replace the six 1.5V AA batteries before starting the test.

NOTE: Nothing will be seen on the display screen until the tester is connected to a battery.

3.Make sure the battery terminals are clean. Use a wire brush to clean them if necessary. NOTE: This tester works best if the battery connectors have been removed and the battery posts have been cleaned. Any corrosion between the tester clamps and the battery connectors, or between

the battery connectors and the battery posts, will degrade the tester’s

efficiency.	• 2 •
