User Manual

INTRODUCTION

Your new Model ATD5490 Battery Diagnostic Tester employs
conductance testing to determine the condition of the battery.

The patented circuit eliminates the need for time consuming CCA
input or conversions to other rating systems. When the TEST
button is pressed, the ATD5490 will immediately display BOTH
the percent available capacity of the battery and the condition
of the battery. The ATD5490 also tests 12V alternator and starter
systems.

Checking Battery Condition

Out of Vehicle Testing

1. Connect the red clip to the positive battery post and

the black clip to the negative post. The battery voltage
will be displayed. Note: use post adapters for side

mount batteries or batteries with top mount threaded
studs (group 31). Connecting to threaded studs will
result in inaccurate readings.

2. For Auto/Truck batteries (390 to 1400 CCA) no size
selection is necessary (default size). The Auto/Truck size

indicator LED will be on.
For Small/Non-Auto batteries (6 Ah to 33Ah) press

selector switch once. The LED indicator will switch to the
Small/Non-auto position.

3. Press and hold down the Test Button until the final
reading is displayed.

The digital display shows percent available capacity.

The Display and Bargraph will automatically revert back
to Volts after approx. 6 seconds, if the TEST Button is
not released.

4. The color--coded LED BARGRAPH will show GOOD
(Green) MARGINAL (Yellow) or REPLACE (Red).

Note: Some batteries may display above 100%. This means
that the available capacity is greater than the rated capacity
